Trek alpha sizing for MTB – what is it?

The old-school approach of measuring the frame size of Trek bikes is a thing of the past. With newer inventions and modern bike geometry, alpha sizing is used in place of numeric sizing on Trek mountain bikes.

Why is alpha sizing important?

1. Easier approach

Instead of using size numbers like 19.5, the sizes can be classified into S, M, ML, L, XL, and XXL. So, someone with a 17.5 size can go for the medium and a 19.5 is a large size. You don’t have to keep a tab on numbers; instead, the alphabet makes it easier.

2. Measurement based on reach

In earlier times the frame size measurement of Trek bikes was solely based on seat tube length. Things have changed, and modern mountain bike geometry focuses more on reach as of now. Hence, alpha sizing measures what matters and is a more simplified way of measuring bike size.

Trek sizing – virtual vs actual

This can puzzle you a bit as they both are somewhat similar yet there is a subtle difference. Actual size can be termed as the overall length of the seat tube from the center of the bottom bracket to the center of the top tube intersection with the centerline of the seat tube.

On the other hand, virtual sizing is the overall length of the seat tube ranging from the center of the bottom bracket to the mid-point of the imaginary horizontal top tube in which it connects with the seat tube.

If I had to give you an example, a bike might have a virtual size of 18.5 and an actual size of 17.5. This means that the bike size feels like 18.5, but in actual sense, the frame size is 17.5. It doesn’t make much of a difference as it is there only to let you know what it is (actual size) and what it looks like in size (virtual size).

People also ask

Trek 17.5 frame size – what does it mean.

A 17.5 frame size is considered an M size (Medium) in terms of alpha sizing. Any individual who is 161-172 cm or a height of 5’3.4”-5’7.7” . If you are within this height range, going for a medium size shall be the right choice.

Trek medium frame size is for what height?

A medium size frame size (17.5) is ideal for a person with a height between 5’3.4”-5’7.7 ”. In centimeters, it is ideal for those around 161 to 172 cm in height.

Trek 24-inch bike is for what age?

When it comes to children, their bikes are measured in terms of wheel size instead of the standard frame size. These kid’s bikes have a size range between 12-26 inches, depending upon the height of the kid.

As far as a 24-inch wheel size is concerned, any kid between the ages of 8-11 can go for a fun ride with it. Some of the popular 24-inch bike models are Trek Roscoe 25, Wahoo 24, Trek Precaliber 24 , etc.

Trek 26-inch bike is for what height?

A 26-inch wheel-size bike is for kids with a height of 4’9”-5’3” (146-160 cm) . Wahoo 26 is a prime example of a bike in this category.

Trek 20-inch bike is for what age?

Trek 20-inch bikes are for children between 5 to 8 years of age. Additionally, if they are within the height of 3’9”-4’6” , it should be suitable for them.

Are Trek bikes good?

Trek bikes are considered to be extremely good and solid in build. It is known to be the number 1 performance bike brand all over the globe. Having its humble beginning in the year 1976 in Waterloo, Wisconsin, it has turned into the largest bicycle manufacturer all over the world. With an array of bikes ranging from, mountain, road, electric, and kids bikes, there is a lot to choose from a mammoth list.

How much is a used Trek bike worth?

It depends on a lot of factors in terms of how old the bike is, the year of production, which model, and a lot more. However, it can be within $1000-10,000 (depending on the model and other factors) .

Where are Trek bikes made?

The majority of their bikes are manufactured in Taiwan, China, Netherlands, and Germany too.

Why are Trek bikes so expensive?

Usually, the bike brand prefers top-tier components, suspensions, and frames that are ahead of its competitors. This results in additional costs that can be seen in the price tag and also many top-end Trek bikes are custom-made with less production, leading to being more expensive.

Trek bikes are a class apart in many ways with a range of bikes on offer for its fans across the world. Choosing the right size for you can be tricky, but this is where the Trek frame size chart comes to the rescue.

Trek as a bicycle brand might be on the costly side, but they punch above its weight to provide top-class bikes for the masses. I am always someone who roots for quality, and Trek provides what I need.

One comment

Thanks for your informative post. I really like the Trek alpha sizing for MTB because Trek frame sizes use alpha sizing rather than the usual inches or centimeters (cm), and they usually have a certain range of measurements.

Bike Size Chart: How to Choose the Right Bike Size? (GUIDE + Calculator)

Profile picture of Petr Minarik - the founder of cyclistshub.com

This guide will teach you how to choose the right bike size using bike size charts and other methods. It covers the most popular bike types, including hybrids/city, mountain, and road bikes .

Use this interactive calculator that recommends a bike size based on your inseam length and bike type. Alternatively, choose the bike size based on one of the three methods explained below .

Bike Size Calculator

DISCLAIMER: Please remember that the calculator does not consider your height, which may affect your bike size.

What Bike Size Do I Need?

To determine which bike size you need, use one of the following methods, sorted from the simplest to the most complex. Remember that simpler methods are less precise, while more complex methods offer greater accuracy.

Method #1: Bike Size Based on Your Height (The Easiest Method)

This is the easiest and quickest method to select a bike size. All you have to do is compare your height with the general bike sizing chart below .

However, this method doesn’t consider the type of bike, so it may not be as accurate as the methods below. As a result, the bicycle may not fit you perfectly.

Method #2: Bike Size Based on Your Inseam Length and Bike Size Chart

This is probably the best bike sizing method for most people. It is based on measuring your inseam length at home and comparing it with a bike size chart .

Once you measure the inseam length, use it to select the bike size. Most bicycle manufacturers use seat tube length and other details, including the standover height, in their bike size charts.

The standover height is the distance from the ground to the top of the top tube.

An illustration of a bike size based on the seat tube length and the standover height

If your inseam length is shorter than the standover height, the bike is too big for you.

The clearance, which is the difference between your inseam length and the standover height, should be around 1 to 2 inches.

This clearance is essential to prevent injuries caused by sudden or emergency stops.

IMPORTANT NOTES

  • The inseam length for choosing a bike size is measured differently from that used for buying pants. Learn more
  • To choose the most accurate bike size, always compare your measurements with the manufacturer’s bike size chart for your bike type.

Hybrid Bike Size Chart

Depending on the manufacturer, hybrid bikes usually come in descriptive sizes (XS-XL) and heights. However, you may still encounter all three types of size designations – in, cm, and descriptive sizes.

And here is a helpful infographic:

Hybrid bike size chart: Choose the hybrid bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in descriptive sizes (XS-XL).

Mountain Bike Size Chart

The size of mountain bikes is typically measured in inches (13″, 19″, etc.) or descriptive sizes (XS-XL).

Generally, smaller mountain bikes usually come with 27.5″ wheels, while larger ones have 29″ wheels.

And here are the sizes in the picture:

Mountain bike size chart: Choose the mountain bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in descriptive sizes (XS-XL).

Road Bike Size Chart

Road bike sizes are usually given in centimeters or descriptive sizes.

You should take extra care when choosing the size of your road bike. Road cycling is a discipline in which you spend long hours in the saddle, so selecting the right bike size is crucial.

It’s also essential to choose the right type of geometry. For instance, endurance geometry road bikes (where you sit more upright) are suitable for beginners, while aggressive (sporty/performance) geometry requires a certain amount of flexibility.

The following road bike size chart also applies to cyclocross and gravel bikes .

And again, an infographic:

Road bike size chart: Choose the road bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in centimeters.

Method #3: Calculating the Bike Size

As we know from Method #2 , bike size is determined by the length of the seat tube. To effectively use this method, you must know the length of your inseam ( learn how to measure it correctly ).

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy.

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy. ( Source )

  • Inseam Length (cm) × 0.685 = Hybrid Bike Size (cm)
  • Inseam Length (cm) × 0.225 = MTB Bike Size (inches)
  • Inseam Length (cm) × 0.665 = Road Bike Size (cm)

1 in = 2.54 cm 1 cm = 0.39 in

After you receive the result, round it up to the nearest whole number. This will match the bike size charts above with a slight deviation.

Example of calculating the MTB Bike Size:

Your inseam length is 33 inches, and you want to buy a new mountain bike. Let’s do the math:

Convert cm to inches: 33 inches × 2.54 = 83.8 cm Calculate the bike size: 83.8 cm × 0.225 = 18.8 ≐ 19 inches

The size of your new mountain bike should be 19 inches .

Example of Calculating the Road Bike Size:

Your inseam length is 70 cm, and you want to buy a new road bike:

70 cm × 0.665 = 46.55 cm ≐ 47 cm

As you can see, your new road bike size should be 47 cm .

How to Measure the Inseam Length?

To measure your inseam length, follow these five simple steps or watch the video below:

  • Prepare a 0.75 to 1-inch (1.9-2.5cm) thick book and a tape measure.
  • Take off your shoes and stand with your back to the wall.
  • Put the book in your inseam, firmly pull it up, and hold it with your tights. Make sure the book is pressed against the wall on one side.
  • Measure the length from the top of the book to the floor.
  • Take the measurement.

NOTE : The inseam for choosing the right bike size is different (a few inches longer) from the inseam used to choose the pants’ size. Remember that inaccurate inseam length may affect the recommended bike size.

How to Measure Your Inseam for a Bicycle

Once you measure your inseam length (and eventually also your height), you can compare it with the bike size chart of the specific bike type. Based on it, you can choose the correct size.

Choosing the correct bike size is easy when you know how to do it. You can use the bike size calculator that recommends a size based on your inseam length and bike type, or try one of the three methods I explain:

  • The first method is simple but not very accurate. You only need to know your height and compare it with the universal bike size chart.
  • The second method is the most accurate. First, measure your inseam length and decide what bike type you want. Then, compare your inseam length with the hybrid, MTB, or road bike size chart, and you’ll have the right size to buy.
  • The third method requires some math but is more accurate than the first. You need to know your inseam length and use special formulas to calculate the size of your next hybrid, mountain, or road bike.

If you’re still unsure about what size bike to choose, please ask in the comments below or email me .

Choosing a Bike Size FAQ

I remember trying to choose the size for my first road bike. I asked a cycling forum for advice because I was stuck between two sizes. The forum members gave me some tips, but most were too complicated for a beginner like me. They suggested that I check the bike’s geometry, but I had no idea how to do that or compare it to my body measurements. So I asked my friend, who has been selling bikes for over 10 years at a local bike shop. He gave me the following advice: “It depends on what kind of rider you are. If you’re a recreational rider, go for a bigger frame. It’s more comfortable because you won’t have to raise the saddle as high as you would with a smaller frame. This will give you a more upright position, which is more comfortable. However, if you’re serious about cycling and want to race, a smaller frame will give you a more aerodynamic and aggressive position. Smaller frames are also more agile and lighter.”

There are several ways to choose the right size bike, but in this guide, I’ll explain three methods: 1. The first method is based on your height and a universal bike size chart. It’s the simplest but not the most accurate method. 2. The second method uses your inseam length and specific bike size charts for hybrid, mountain, and road bikes. It’s the most accurate method for most people. 3. The third method involves calculating the bike size using your inseam length and a unique coefficient that varies based on the bike type. It’s more accurate than the first method but not as accurate as the second. You can also use an interactive calculator that recommends bike size based on your inseam length. I recommend reading the entire article to better understand each method and decide which one works best for you.

Choosing the right bike size is crucial, not only for your comfort but also for preventing health problems. If your bike doesn’t fit you properly, you may experience pain in various body parts, such as your lower back, neck, and hands. ( Source ) According to Physio-pedia.com , there are four essential components of a good bike fit: correct foot position, saddle height, stem length, and handlebar position. However, remember that if your bike is two sizes too small or too big, you won’t be able to achieve a proper bike fit. Therefore, learning how to choose the correct bike size is important. You can avoid discomfort and potential health issues by selecting the right bike size. So, take the time to find the perfect fit for you.

If you have ordered a new bike the wrong size, I recommend returning it as soon as possible. Most online retailers allow returns. If you ride the wrong size bike, you risk injuring yourself (e.g., overloading certain muscles) or not being comfortable in the saddle. It also happens that even experienced cyclists ride the wrong size bike, so they often fail to adjust it to their liking.

It’s a bit complicated. The answer is mostly no, but there are some exceptions. Let me explain. Many people ask this question. But it is a wrongly asked question because bike size doesn’t depend on age. Our heights vary greatly, so a 19-inch bike may suit someone even if they’re not the “correct age” for it. The correct question is: “What height and inseam length is a 19-inch bike for?” With this information and the bike chart for the specific bike, you can determine who the bike is suitable for. Read the entire guide on choosing the right bike size for more information.

A 26-inch bike refers to a bicycle that uses 26-inch wheels. These wheels are commonly found on kids’ bikes, but some adult (mountain) bikes also use them. Nowadays, 27.5-inch and 29-inch mountain bikes are becoming more popular because they offer better comfort and speed. If you’re shorter than 5’0″ (150 cm), a 26-inch bike may be a good choice. However, if you’re taller, I recommend choosing a bike with at least 27.5-inch wheels. Check out this guide to learn more about selecting the right bike size.

how to determine trek bike size

Despite the importance of a bike’s fit and all the potential pitfalls, most people don’t need a bike shop specialist to help them when it comes to selecting a bike size. If you have reservations about buying a bike without seeing it first, you’re not alone. Many people hesitate to purchase a new bike online because they can’t test-ride it.

Before you shop for a bike, you’ll need to take a few body measurements. Bike sizes are based on a person’s height and body frame dimensions — not on weight. You’ll want to know an accurate height and inseam measurement.

In this guide, we’ll steer you through the how-to-measure bike size process so you can feel confident about buying a bike online or with a specialist.

Bike Sizing: How It Works

Wout van Aert and Mathieu Van Der Poel on the attack on stage 11 of the 2022 Tour de France

Many bikes offer sizing that you’re familiar with, such as S, M, L, or XL. But some bikes come in inches, and road bikes usually come in every centimeter measurement.

The frame size of a bike refers to the length of its seat tube. This measurement is given in one of two ways. The “C-T” measurement runs from the center of the bottom bracket (where the cranks enter the bike frame) to the top of the top tube (the horizontal tube that runs between the headset/handlebars and the seat post).

The “C-C” measurement runs from the center of the bottom bracket to the center of the top tube (C-C). This measurement has become less useful because of the propensity of sloping top tubes on modern bikes. Just because you ride 56cm in one brand doesn’t mean you ride 56cm in all brands.

How to Measure Bike Size: Reach and Stack

Trek Emonda Geometry - how to measure bike size

To alleviate this issue, brands nowadays offer detailed geometry specifications to help cyclists discern what the labeled frame size really means. The two most important numbers are reach and stack, which are internationally accepted standards.

Reach is the horizontal distance between the center of the bottom bracket and the center of the head tube. Stack is the vertical distance between the center of the bottom bracket to the top of the head tube. These numbers are much more representative of the actual dimensions of the bike frame than the seat tube-based sizing still used to label bikes.

There is no industry standard for gathering bicycle measurements or fitting the bike to the rider, and the antiquated sizing labels further complicate comparisons between models. But some generalities are still useful. If you have longer legs for the length of your torso, then you will generally fit better on a bicycle with a taller stack. If you have shorter legs but a longer torso, then you will generally want to get a bike with a longer reach.

Also, if you have longer arms, then a longer reach will fit better. And conversely, if you have shorter arms, then a shorter reach will most likely improve the fit. There are also women’s-specific frames, which generally abide with shorter reaches than men’s-specific frames with the same stack.

Still, every bike brand should frame geometry specifications based on their measurement standards. To find sizing and frame geometry charts, check the brand’s website for their preferred standards.

The video below does a good job of explaining reach and stack on a road bike.

What Measurements Do I Need?

Understanding the dimensions and geometry of a bike is half the job. You also need at least two different body measurements to find the perfect bike size for your body structure.

Height:  This is the key first step. Most manufacturers have bike size charts that show the appropriate bike sizes for specific heights. Height alone cannot guarantee a perfect fit, so we recommend that you also get the next measurement.

Inseam length: Stand with your feet planted about 6 inches apart as you would do when you straddle a bike. Measure the length from your crotch to the bottom of your feet. When using this method, it is easiest to have someone with you to help you measure.

If you are alone, use a hardcover book to help measure your inseam. Stand against the wall with bike shoes on; straddle the book, spine up; and mark the wall with a pencil where the book’s spine meets the wall. Then, you can step away from the wall and measure the mark to the floor. Be sure to measure several times for accuracy.

Almost every brand has an online sizing guide for each of its models. These guides are sufficient for most riders, but some will be on the cusp between sizes, and some will have specific needs based on dimensions that may not be “average.” If you know the reach and stack of a current or former bike that worked well for you, you can work backward from there by referencing the geometry chart.

Those on the cusp between sizes will have to choose between prioritizing the stack or reach and then choose to go up or down on the size. If you value the standover height more than the horizontal length, then you would size down. This is more common on mountain bikes and commuter bikes since, as standover height is more important.

If you value the reach over the stack, then you would normally size up. This is more common on road and gravel bikes, as the riding position is much more static and usually held over a much longer time period.

How to Measure Bike Fit: Bike Type & Sizing

Road bikes and gravel bikes are much more sensitive to the reach measurement than mountain bikes. This is because, for the majority of riding time, you are seated in a fixed position, and the bike is mostly horizontal. Your body is much more static, so having too long or too short a reach becomes more apparent as the miles pile on.

The fore and aft saddle position should be set based on your hip’s relationship to the pedals for proper biomechanics and efficiency. This adjustment should not be used to correct for the improper reach. Different length stems can be used to dial in the reach, but there is a limit to this before it starts negatively affecting handling.

Canyon Spectral K.I.S. all-mountain bike review, Keep It Stable enduro trail riding, air

Mountain bikes are much less sensitive to reach, as you stand and use various body positions, and the bike’s attitude constantly changes as well. The bike and you are almost never in a static position for very long, so the reach issue isn’t as prominent. Standover height is much more of an issue on mountain bikes, but modern bikes usually have plenty of this for each size.

Once you get the bike, you can — and should — take it to a local bike shop for a once-over. While there, they can help dial in these small adjustments that can drastically improve your fit. And they can suggest parts that may aid in this process.

How to Choose the Right Bike for You

Different types of bikes have their pros and cons, but there’s no best or worst. The right bike is the one that you find comfortable, practical, and enjoyable to ride.

Picking the right bike is a personal decision, so make sure to do your homework and have a realistic budget in mind. Bike prices certainly have risen over the years, and biking popularity has spiked since the beginning of the COVID-19 pandemic, exacerbating these price jumps. But the market has been self-correcting some since then.

The hardest part of the process is deciding what type of bike to purchase. Once you’ve pinpointed the type of bike that fits your needs, then it’s time to focus on specific guidelines for how to measure the bike’s size, functionality, and comfort.

How Do I Know if My Bike Fit Is Right?

The correct bike fit allows for efficient and pain-free pedaling dynamics and a comfortable fit for the rest of the body for even extended rides. When seated in the comfortable position on the saddle, the knee should roughly be over the pedal spindle with the crankarm horizontal to the ground, and with the heel level with the ball of the foot.

The hip angle shouldn’t be too closed off, and the back should be able to be relatively straight with the arms comfortably extended with hands in the normal riding position on the handlebars.

Should I Size Up or Down?

If you are in between frame sizes, you need to decide if you want to prioritize the overall height of the bike (stack) or the overall horizontal dimension (reach). This also depends on what kind of bicycle you want.

If you want to prioritize the height more than the length, then size up. This is more prevalent in mountain bikes and commuters, as the standover height is usually more important.

If you want to prioritize the horizontal length, then size up. This is more common on road bikes and gravel bikes, as the seated position is much more static, and this dimension becomes more important for longer-distance cycling.

What size bike do I need? A comprehensive bike size guide

How to decode a geometry chart to find the right size bike for you

Bikesize

Head tube angle

Seat tube angle.

The most crucial factor when buying a bike is to make sure the frame fits. Just like how you might wear a size 10 shoe in Nike and a 10.5 in Adidas, there is no standardisation when it comes to bike frames, and sizing can vary drastically from brand to brand. Worse, trying to decode a geometry chart for some can be as hard as wrapping their heads around quantum physics.

While minor adjustments can be made with stem length and saddle setback, ultimately if a bike frame is too big or small, the amount of available adjustment won't be great enough, and it will influence the bike's handling characteristics as well as cause issues when it comes to comfort. This is especially true when riding one of the best road bikes because you will essentially maintain that same position for the duration of the ride, and if it’s wrong, you’re in for many hours of pain — the bad kind, that is.

What makes things even more complicated is that people are built differently; some people have short torsos and long legs, while others have a long torso and short legs. This means two people who are the same height might not fit on the same bike.

While we can’t offer a specific chart that will tell you exactly what size frame will be perfect for the dimensions of your body, what we can do is help to demystify the numbers on the geometry chart and show you how to use them to figure out the right size for you.

Luckily, the components on a bike do allow for a little bit of leeway. Saddles usually have around 7cm of fore-aft adjustability, stems can be swapped for shorter or longer versions with shallower or steeper angles that raise or lower the handlebars, and most of the best road handlebars can be bought in a choice of around five different widths. Cranks can be swapped for shorter or longer lengths, many seatposts are available in a couple of shapes that adjust their bend, known as 'layback', and some bikes even come with flip chips that adjust the geometry. 

However, don't think that gives you a free ride when deciding which size bike you need. Just like how a house with poor foundations will fall, if your bike's foundation - the frame - is incorrect, you're setting yourself up for a bad time. 

Bike geometry

A geometry chart comprises measurements of almost everything to do with the frame. Some of these numbers are extremely helpful in gauging whether a frame will fit your body or not, while others can be ignored entirely. Here's a rundown of the important numbers, and what they mean. 

Top tube length and effective top tube length

When we request bikes in for review, the first figure we look at is the top tube length or, more often, the effective top tube length. This is the length from the head tube to the seat tube and is the measurement most brands base their sizing around. 

Bike size guide

The top tube and effective top tube length can differ because of the modern compact or semi-compact geometry bikes. Old school road bikes see a completely horizontal top tube, while the top tube on most modern bikes slopes downward. This can increase the length of the physical section of tubing but does not increase the actual distance between the head- and seat tubes.

The top tube relates directly to your arm and torso length, and it is a figure that doesn’t leave a ton of leeway to be fixed. If you have a bike with a top tube that is too short or too long, small deficits can be remedied with a new stem of different length. Realistically there is about 20mm of leeway shorter or longer than a stock road bike stem, any longer or shorter, and you will drastically change the handling characteristics of your bike.

Reach is a slightly more difficult measurement to get your head around and refers to the horizontal distance from your bottom bracket to the top of the head tube.

If you were to draw a line from the centre of the bottom bracket straight up through the frame and one from the centre of the head tube back; 'reach' is the horizontal distance between the head tube and the vertical line.

Reach is the key measurement for mountain bikes as the majority of your time on the bike will be in a standing position, with your saddle well behind your body, making the length from the head tube to the seat tube somewhat irrelevant — because you’re not actually sitting on the seat.

For road riders, reach tells us exactly how far you have to ‘reach’ to grab the handlebars and is not subject to wonky measuring and sizing practices between brands. Because of this, it is one of the two key figures to determine how one bike compares to another.

For example, a Trek Emonda has a reach of 386mm in a size 54cm frame, a Specialized Tarmac SL7 has a reach of 387mm also in a size 54cm, and a Scott Addict RC has a reach of 389mm in size 54cm. While the difference is only a few millimetres, each one of these race bikes, which are supposed to be the same size, are actually a little bit different. 

Bike size guide

Stack is the other key sizing figure which denotes the vertical distance between the bottom bracket and the centre of the head headtube — measured using the same imaginary line that we drew straight up out of the bottom bracket when we measured reach. 

The frame stack height measurement tells us how upright or aggressive a rider's position will be on the bike. Racers tend to prefer a shorter stack because it allows them to get their handlebars low to remain lower, more aerodynamic, and shift more weight over the front wheel for cornering. Endurance and beginner riders are usually better suited to taller stacks because it allows for a more upright, comfortable position. 

Small adjustments to the overall stack height can, of course, be made by using angled stems and spacers, but again, this is not unlimited.

For example, Cannondale’s endurance bike, the Synapse, has a frame stack of 570mm in size 54, while the SuperSix Evo race bike measures 554mm in the same size.

Other important measurements

When choosing the right size for you, the measurements above will be the go-to numbers, however, if you find yourself between sizes, or you want to choose between two similar-sized bikes from different manufacturers, the following measurements can help when it comes into the nuanced differences that will affect the ride feel, stability, handling and more. 

Seat tube length and standover height

Bike size guide

Seat tube length is one of the more simple measurements on a bike and is the distance between the centre of the bottom bracket to the top of the seat tube (excluding the seatpost, which is adjustable, of course). 

In the olden days, bikes were sized based on their seat tube length because it was usually the same as the top tube length; this was before the introduction of sloping top tubes and compact frame geometries. While a select few brands, like De Rosa, still size their bikes based on seat tube length, most use the top tube length, if they haven’t opted for t-shirt style small/medium/large sizing. 

Seat tube length is still relevant, however, as it provides an insight into a bike's standover height. Too high a standover height, and your bike may leave you with a bruised undercarriage when you stop and climb off. There really isn’t such a thing as too low a standover height; modern mountain bikes are the perfect example of this. That said, as seat tube length and standover height are proportional to the rest of a bike’s geometry, it may signify the need for a bigger frame.

The head tube angle of a bike doesn’t actually tell us anything about the size of a bike, but instead provides an insight into its handling characteristics; although as with everything else, it's not the only determining factor. Fork rake, trail, stem length, handlebar width, chainstay length, and even BB height and drop all affect how a bike handles. 

A steeper head angle will be a higher number, offering sharper, more responsive handling, and delicate inputs can illicit mid-corner line changes. With the handling being so light, bikes with steep head angles can sometimes feel nervous at high speed. A slacker head angle (lower number), on the other hand, will be more stable, especially at speed, but will require a bit more gusto to change your line.

Race bikes generally see head tube angle between 72.5 and 73 degrees, endurance bikes are often between 70 and 72 degrees, and cyclocross bikes usually range from 70 to 71 degrees — of course, there are outliers in every category.

Bike size

The seat tube angle is, you guessed it, the angle of the top of the seat tube, relative to the centre of the bottom bracket.

Usually, on smaller bikes, the seat tube angle will be a bit steeper as riders with shorter legs need to be closer to the BB than riders with longer legs.

On mountain bikes, seat tube angles have increased dramatically as the geometries have become more progressive to help riders maintain traction on steep and technical climbs. On the other hand, road bikes have remained relatively stable, clocking in around 74-degrees, give or take a few degrees depending on the size and style of bike. 

While the seat angle of a frame is set, adjustments can be made via a setback seat post or the fore and aft on the saddle rails. The position you’re shooting for is to have your knee directly above your pedal axle with the crank when your foot is at the three o’clock position.

Bike geometry comparison

One problem we face when buying a bike is that each brand lays out its geometry charts in a different way, and this makes comparing two bikes from two separate brands difficult. Expand that to five bikes from five brands and you can get lost in the numbers in no time. 

Thankfully, we clearly weren't alone in finding it a headache, as a few clever people have built tools that simplify bike geometry comparison. 

Our go-to choice is Geometry Geeks , where you can simply search for the bikes you wish to select, hit compare, and it will bring up a standardised table that allows you to easily see the differences between your chosen frames. Others such as Bike Insights and Velogic Fit provide a similar solution. 

So what does this all mean?

We have thrown quite a lot of general information at you here, and hopefully, you’re better equipped to decode the geometry chart of that new bike you’ve been lusting over.

But how do you take this information and figure out what size bike is right for you? Below is a basic size chart based on rider height to get you within the ballpark.

Bike size guides

Remember, that table is only providing a rough ballpark. To get a better idea of what size bike you need to choose, you should consult the size guides provided by the brand you're looking to buy. Online retailers like Competitive Cyclist, Jenson USA, and Bicycles Online also have pretty good sizing calculators that provide you with a decent starting point. However, even armed with this information, you should still only use it as a guide. The geometry charts are the true determiner of whether or not a bike will fit, and if so, how it will fit.

You will notice that we have only included effective top tube length in the sizing chart above, and have not included the t-shirt style sizing employed by some brands. This is because even among those that use small/medium/large to size their bikes, there is no standardisation. For example, a size M Giant TCR Advanced SL 0 Disc has an effective top tube length of 555mm while size M Ridley Helium SLX disc has a top tube length of 565mm — the size small has an effective top tube of 545mm. If you look at our basic size chart above, these fall into two different height categories. So if you are 5ft 9in tall, like this writer, you would ride a size M Giant and a size S Ridley.

The best way to find out if a bike fits is to go down to your local bike shop to try a few out and see what feels right. If possible, go and get a professional bike fit before you pull the trigger, or at the very least, get your local bike shop to help you choose the right size. 

If you want to maximise your comfort and efficiency, our bike fit guide explains all the areas that can be adjusted to improve your comfort. Alternatively, a professional bike fit on your own bike will help you to dial everything from your saddle height to how many spacers you need down to the millimetre.

How to measure a bike frame: our complete guide to sizing a bike

Fundamental measurements so you can compare frames like-for-like

Simon Bromley / Immediate Media

Paul Norman

If you’re thinking of buying a new bike, or a first bike, understanding the key measurements that define your frame is important to ensure you get a machine that fits you and works for the type of riding you intend to do.

And if you’re planning to rent a bike, it’s useful to know your frame’s key measurements, so you can make sure your rental will be comfortable to ride and can be adjusted to fit.

Not all manufacturers measure frame sizes in the same way, so you need to look at a few fundamental measurements to ensure you’re comparing apples with apples.

Read on to find out how to size up your road bike or mountain bike frame to ensure you get the right bike fit . Also check out our comprehensive guide to mountain bike geometry , which tells you how these measures affect handling; even if you’re a roadie, most of the measurements are still as significant.

We’ve also got advice on how to choose the right size frame for road bikes and mountain bikes and specific advice for choosing a women’s bike .

Bike geometry measurements

We’ll tell you below how to measure the key numbers that define your bike. But first, here’s a quick rundown of those numbers:

  • Top tube length: the horizontal distance between the centreline of the head tube and seatpost
  • Seat tube length: the distance between the centre of the bottom bracket and the top of the seat tube
  • Reach: the distance between the bottom bracket and the top of the head tube
  • Stack: the vertical distance between the bottom bracket and the top of the head tube
  • Wheelbase: the distance between the front and rear axles
  • Chainstay length: the distance between the bottom bracket and rear dropout 
  • Front centre: the distance from the bottom bracket to the front axle 
  • Seat tube angle: the angle of the seat tube in relation to the ground
  • Head tube angle: the angle of the head tube in relation to the ground 
  • Bottom bracket drop: the difference between the height of the wheel axle and crank axle
  • Bottom bracket height: the distance from the ground to the bottom bracket

What you’ll need to measure a bike frame

To measure a bike frame you will need four tools:

  • A tape measure
  • A clinometer to measure angles (there are free smartphone apps you can download)
  • A long spirit level (or you can use the clinometer app and a straight piece of wood)
  • A plumb line (or you can improvise with string and a couple of blobs of Blu Tack)

Most bikes, whether road or mountain, are now measured in metric units, but you may find some manufacturers that still size mountain bikes in inches. Some brands, such as Moots, even mix the two.

We highly recommend you stick to metric units to keep things consistent. If you really must, you can always divide centimetres by 2.54 to switch to inches.

You will usually be able to find a geometry chart for all sizes of a current frameset on a maker’s site. If your bike is still a current model, it’s worth taking a copy of this because it will be more accurate than your measurements and likely a handy reference down the line.

How to measure top tube length

Top tube measurement demonstrated on a bike frame

Once, bikes all had horizontal top tubes. Now many bikes’ top tubes will have a slope.

If you look at a bike geometry table, it will usually include the real top tube length. But for a consistent measure, regardless of the top tube angle, you need to measure the horizontal top tube length, called the effective top tube length or virtual top tube in many geo charts.

That’s the horizontal distance between the centreline of the head tube and the centreline of the seatpost. Measuring it correctly will mean using your spirit level or the clinometer app, to ensure your measure is really horizontal.

Many manufacturers size road bikes by top tube length. That’s not true of mountain bikes, where the frame size is usually marked S, M, L, etc. That’s a system used for some road bikes too: Merida’s road bikes go through S, S/M, M/L and L.

Of course, this measurement is up to each brand's interpretation – Ridley’s size-S frames have a top tube of around 54cm, which is equivalent to many brands’ size-medium frames.

It’s worth noting that not all brands measure virtual top tube length in the same way either.

Colnago, for example, records the horizontal distance from the head tube to a vertical projected up from the top of the seat tube, so it doesn’t take account of the further backward projection of the seatpost and its numbers will come out smaller than other makers’. A 50s Colnago is equivalent to a 54cm top tube.

How to measure seat tube length

Seat tube measurement demonstrated on a bicycle frame

Seat tube length is the straight-line distance between the centre of the bottom bracket and the top of the seat tube.

Again, it’s trickier than it sounds: some bikes such as the Trek Madone have a considerable extension of the seat tube above the top tube junction, while others use a seatmast, so it’s difficult to compare with an alternative’s dimensions.

Plus, mountain bikes in particular often have a kink in the seat tube, so you don’t want to follow the line of the tube itself, which will be longer.

Line up your straight edge with the bottom bracket centre and the top of the seat tube and measure along this, if you’re not sure you’re following the right line.

How to measure reach and stack

Stack and reach measurement demonstrated on a bike frame

So we’ve seen that top tube and seat tube lengths are a bit of a minefield if you want to compare frames. For more consistency, most manufacturers will now show reach and stack values for their bikes.

These have the advantage of being independent of frame design and measure the perpendicular distances between two key contact points: the bottom bracket and the top of the head tube.

We’ve published a more detailed explanation of why reach and stack are important here .

In brief, the reach is the horizontal distance between the two. To measure it, you’ll need your spirit level again.

Attach a plumb line to the end of the level. If you’re using Blu Tack, make sure the blob at the end of the string is fairly symmetric and your string hangs down straight, otherwise your measure may be off.

Align the top edge of the level with the centreline of the top of the head tube. Then move the level back and forward until the plumb line intersects with the centre of the bottom bracket spindle. Now just measure the distance between the top of the plumb line and the head tube and you’ve got your reach.

Another option is to push your bike up against a wall, measure the distance to the top of the head tube and the distance to the bottom bracket, then subtract one from the other. You’ll still need to make sure your measurement is horizontal though.

The stack is the vertical distance between the bottom bracket and the top of the head tube. So once you’re set up to record your reach, you should also be able to measure your stack, following the plumb line.

An alternative method is to measure the vertical distance from the ground to the top of your head tube, then measure the height of your bottom bracket from the ground and subtract this.

Both reach and stack are quite fiddly to capture. You’ll probably need a second pair of hands if you use the plumb line method and it’s worth repeating to ensure you’re consistent.

How to measure wheelbase

Wheelbase measurement demonstrated on a bike frame

Your frame’s wheelbase is the distance between the front and rear axles. It’s a key determinant of a frame’s ride quality and will vary with frame size too.

It’s fairly easy to measure, although you need to set the fork straight ahead or your measurement will be incorrect.

Like reach and stack, it’s worth repeating the measurement several times to make sure you get the same number. Accuracy will also be increased if you measure the wheelbase on both sides of the bike and take the average because this will compensate if the fork is not quite straight.

How to measure chainstay length

Chainstay length measurement demonstrated on a bike frame

Chainstay length is one of the two components that make up your wheelbase and, again, contributes significantly to your frame’s handling characteristics. A frame with shorter chainstays will typically feel more lively than one where the stays are longer.

The chainstay length is the straight-line distance between the centre of the bottom bracket axle and the centre of the rear dropout, so it’s fairly easy to measure with a ruler.

How to measure front centre

Front centre measurement demonstrated on a bike frame

The other component of the wheelbase is the front centre. That’s the equivalent of the chainstay length but measured from the axle to the front dropout.

Again, it affects handling, as well as toe overlap with the front wheel. It’s not often quoted by bike makers, but BMC, for example, shows it on its geometry charts.

Note that the wheelbase is not the sum of the chainstay length and the front centre, because neither of these is measured horizontally.

How to measure seat tube and head tube angles

Seat and head tube measurements demonstrated on a bike frame

The seat tube and head tube angles are two of the most important factors in determining handling, with more upright tube angles typically leading to more nimble handling. Your clinometer app will come in useful here.

If you’ve got a straight seat tube, you can measure the seat tube angle by lining up your smartphone and reading the number from the clinometer app. Make sure your bike is vertical and standing on a horizontal surface for an accurate reading.

If there’s a kink in your seat tube, you’ll need to use a straight edge to follow the line between the bottom bracket shell and the top of the seat tube, then line up the phone with this.

Most newer bikes will have tapered head tubes, so the angle of the front of the head tube will not be the same as the angle of its centreline.

You can get close to the latter by holding your phone at the angle of the centreline, or by using a straight edge to line up with the centres of the top and bottom of the head tube.

If you have straight fork legs, without an angle at their crown, the angle of the legs will be the same as the head tube angle, so you can measure this instead. Again, it’s important to have the bike standing vertically.

You can also measure head tube angle by lining up the clinometer with the steerer extension above the head tube.

How to measure bottom bracket drop

BB drop measurement demonstrated on a bike frame

The bottom bracket drop is the difference between the height of the wheel axles and the centreline of the crank axle.

You can measure it by finding the height of the rear axle and the height of the bottom bracket, then subtracting one from the other. It’s another key measurement quoted by bike brands on their geo charts.

How to measure bottom bracket height

Bottom bracket height measurement demonstrated on bike frame

Finally, the bottom bracket height is the distance from the ground to the centre of the bottom bracket shell. So that’s quite easy to measure, although be careful to keep your bike straight upright for an accurate reading.

Unlike bottom bracket drop, it will be affected (slightly) by your tyres too, so inflate them to your usual running pressure.

Now you’ve got all the measurements you need to size up your frame, and help with any purchasing decisions in the future, whether that's a new or second-hand road bike, commuting bike or gravel bike . Keep your numbers somewhere safe though: you don’t want to have to repeat the process.

If you still have questions or need further guidance after reading the bike frame size charts below, feel free to reach out in the comments and we’ll help you find the perfect bike size for your height.

Choosing the right bike size is essential for comfort, efficiency, and preventing injuries.

While test riding a bike is the ideal way to gauge fit, it’s not always practical, especially with the often better deals found online compared to local bike shops.

The good news is, you DON’T NEED TO test ride a bike to ensure a good fit. 

If you know your height and inseam length, you can get the right size by using a bike size chart.

However, this is where things get slightly more complex.

Bike manufacturers may use different sizing standards, such as centimeters and inches, or sizing labels such as S, M, L, XL. Sizing methods also differ based on bike types—road, mountain, and hybrid bikes are not sized in the same way.

If you’re starting to feel overwhelmed, don’t worry. Keep reading below and we’ll make things a lot clearer.

Should You Trust S, M, L, XL Bike Size Labels?

Many manufacturers also use size labels such as XS, S, M, L, and XL. These labels are becoming more common because they simplify things, but they can sometimes be vague and misleading.

Due to the lack of standardization across brands and bike types, you should avoid relying only on bike size labels when choosing the right size. Their dimensions may vary from one brand to another.

Letter-based size labels offer a good starting point but should be cross-checked with other methods.

For example, an L-sized Trek road bike may have a 56 cm seat tube length, while a Giant’s L-sized road bike may have a 58 cm seat tube length.

Therefore, you can use these labels as a rough guide, but make sure to also refer to a bike type-specific size chart (such as the ones below) or the manufacturer’s sizing chart for the specific model you’re interested in.

What and How to Measure?

To be able to use a bike frame size chart and correctly size a bike, you need to know two measurements: height and inseam (inside leg) length.

Why does inseam length matter?

The inseam length is important to ensure you get a bike with an appropriate standover height. This is the distance from the ground to the top of the bike’s top tube.

Ideally, to prevent injury and improve comfort, there should be a one-to-two-inch clearance between your crotch and the top tube when standing over the bike.

What you’ll need:

  • A tape measure
  • 30 seconds of your time

Measuring your height  is super simple. All you need to do is:

  • Stand straight against a wall with your feet together.
  • Place a book on top of your head, making sure it’s horizontal with the floor.
  • Measure the distance from the ground to the point where the book and the wall meet.

Measuring your inseam is even simpler:

  • Just stand against a wall with your shoes off and feet hip-width apart.
  • Measure the distance from the ground to your crotch.
  • That’s it!

With these two measurements written down, you’re pretty much all set to find the perfect bike size for your height and inseam.

Adult bikes are primarily sized by the frame; or to be more specific, they are sized by the seat tube length .

This is the vertical distance from the center of the pedal axle (the bottom bracket) to the top of the seat tube—it’s often listed in measurements like 52 cm, 54 cm, 56 cm , or 17 inches, 19 inches, 21 inches .

While this measurement is a good starting point, it doesn’t tell us all that we need to know—it determines the height of the bike, but not its length, also known as reach.

Why Does Reach Matter?

To really dial the fit, you should also consider the bike’s reach , which refers to the horizontal distance between the bottom bracket and the head tube.

Reach tells you how far you have to stretch to reach the handlebars and is especially useful if you’re in between two sizes.

A shorter reach means you’ll be sitting more upright when you’re riding—perfect for comfort on longer rides.

A longer reach means you’ll be more stretched out on the bike—ideal if speed and aerodynamics are your priorities.

Men’s vs. Women’s Bike Sizing

In adult bike sizing, the distinction between men’s and women’s bikes often comes down to marketing rather than significant sizing and design differences.

Therefore, the bike frame size charts below are suitable for all riders , regardless of gender.

Women and men bikes

Even though some brands offer models specifically labeled for men or women, and a few brands manufacture women’s bikes only (such as Liv or Juliana), the differences compared to unisex bikes are miniscule.

Men’s and women’s bike sizes are largely similar, with only minor differences driven by marketing. Most bikes are unisex!

These often include slightly different proportions between the bike’s stack (vertical height) and reach (horizontal length), which are negligible unless you’re a professional rider.

For example, women’s models might have a shorter reach compared to the stack to accommodate what some manufacturers perceive as average body proportions.

However, as body types differ among individuals, a women-specific bike might not automatically provide a better fit for every woman. Similarly, some men might find that a women-specific model fits them better than a men’s or unisex model.

Kids’ Bike Sizing: Sized by Wheel Diameter

Unlike adult bikes which are measured by frame size, kids’ bikes are determined by wheel size , simplifying the selection process.

Kids bike size

Wheel diameters on kids’ bikes typically range from 12 inches to 26 inches , increasing in two-inch increments. This means that a 12-inch kids’ bike has 12″ wheels, a 14-inch bike has 14″ wheels, and so on.

Manufacturers then use these wheel size measurements to provide size recommendations based on a child’s age, inseam length, or height.

For example, a 12-inch bike might be suggested for children ages 3 to 5, with specific height or inseam measurements to further dial the best fit.

Many manufacturers provide additional information such as standover height and min/max seat height , which allows parents to get a better fit by relying on the inseam length measurement.

While wheel diameter and age can give a general idea of the right bike size, incorporating inseam length in the equation is advisable for the perfect fit.

While most adult bikes are sized by the frame, specifically by the seat tube length, sizing standards can differ slightly based on bike types.

For example, road bikes are typically measured in centimeters (cm), mountain bikes are measured in inches (in), while hybrid bikes may use either of the two.

Therefore, finding the ideal fit means you should be checking out bike type-specific sizing charts for road, mountain, and hybrid bikes, such as the ones below!

In recent years, mountain bike manufacturers have moved away from the traditional method of sizing bikes by inches and seat tube lengths.

Nowadays, a more intuitive system using size labels such as S, M, L, and XL is in use, prompted by more radical modern frame designs and geometries.

In addition to that, most brands also provide detailed geometry charts where you can find important measurements such as stack, reach, tube angles, wheelbase, and so on.

Our mountain bike size chart below is a great starting point.

26-Inch vs. 27.5-Inch vs. 29-Inch Wheels

Modern mountain bikes typically come with 27.5-inch or 29-inch wheels, whereas 26-inch wheels are mostly reserved for fat-tire bikes.

The choice of wheel size directly influences the bike’s handling and performance—smaller wheels improve handling and maneuverability, whereas larger wheels enhance speed and obstacle rollover ability.

However, when considering the right fit for a mountain bike, the impact of wheel sizes is limited and more nuanced.

In general, wheel sizes should not be used as a way to gauge the right fit of a mountain bike, even though it can affect the riding experience by changing the geometry of the bike.

Wheel size is crucial for riding performance, but not as important for sizing adult bikes.

For shorter riders, smaller wheels can improve the feeling of maneuverability and control, improving the riding experience. Smaller wheels also lower the standover height, which has a positive effect on comfort and safety.

Conversely, taller riders may prefer larger 29-inch wheels for smoother handling and the ability to maintain momentum.

This is why many manufacturers often align wheel sizes with frame sizes—smaller frames come with 27.5-inch wheels, whereas larger frames come with 29-inch wheels.

What If You’re Between Two Sizes?

If you find that you’re between two sizes on our mountain bike frame size chart, there are a few things you should consider to be able to choose correctly.

  • Riding style: Size up if you’re an aggressive rider or size down if you’re more timid in your approach.
  • Stability vs. maneuverability: If you prioritize stability, size up; but if you prioritize maneuverability, size down.
  • Approaching obstacles: If you prefer taking the harder line and going over obstacles rather than around them, size up. Otherwise, size down.
  • Ape index: If your wingspan is longer than your height, size up; otherwise, size down.
  • Experience and flexibility: If you are an experienced rider and have a flexible body, feel free to size up. Otherwise, size down to feel more confident.

Road bikes are typically sized in centimeters by measuring seat tube length. Most manufacturers also use the letter-based size labels.

However, with the introduction of modern frame geometries with sloping top tubes, it’s a good idea to also consider more advanced geometry measurements, such as stack and reach.

This approach offers a more precise fit, ensuring optimal performance and comfort on the road.

Below, our road bike size chart offers the perfect starting place to pinpoint your ideal frame size.

Note: This chart can also be used to find the right gravel and cyclocross bike size due to their similarity to road bikes.

If you’re between two sizes on our road bike size chart above, you’ll want to consider these factors before making the final choice:

  • Riding for speed:  If you prefer faster and shorter rides and races (such as crits), choose a smaller frame.
  • Riding for endurance: If you prefer long-distance riding, such as gran fondos or audaxes, choose a bigger frame.
  • Ape index:  If your wingspan is longer than your height, choose a bigger frame. Otherwise, choose a smaller frame.
  • Riding position:  If you prefer being more upright when riding, choose a smaller frame. Otherwise, choose a bigger frame for more aerodynamics.
  • Weight and stiffness: If you want a bike that feels stiffer and lighter (e.g. for sprinting), choose a smaller frame.

Hybrid bikes blend the characteristics of road and mountain bikes, prioritizing comfort, practicality, and versatility.

Most manufacturers size hybrid bikes (including commuting and fitness bikes) using the letter-based approach (S, M, L, XL).

This makes it easy to find the right size, especially considering the fact these bikes are used for recreation and commuting, rather for performance.

Choose your ideal hybrid bike size from the chart below.

If you’re between two sizes on our chart above, here are a few things to consider:

  • Ape index: If your wingspan is longer than your height, choose the larger frame size.
  • Riding style: If you plan to ride for leisure or commuting, a larger frame might offer a more relaxed posture. For more sporty fitness riding, a smaller frame will provide better control and handling.
  • Standover height: Make sure your inseam length is at least 1-2 inches longer than the standover height on the frame size you’re considering.

As we’ve already mentioned briefly above, kids’ bikes are sized by the wheel diameter. This makes choosing the right size a lot more straightforward.

Check out our kids’ bike size chart below to get a general idea of which sizes to consider for your child.

But remember, for the best fit, it’s a good idea to measure your child’s inseam and compare it to the bike’s standover height and seat height range.

Finding the right bike size using a sizing chart is pretty straightforward and a great start.

But how do you know if your bike actually fits you perfectly?

Here’s a quick checklist to help you easily determine if your bike fits you well.

  • Standover height:  If the bike fits you well, there should be 1-2 inches of space between your crotch and the bike’s top tube. This is especially important on bikes with a horizontal top tube design. To check, stand over the bike with your feet flat on the ground and pull the handlebars up. If the front wheel can come up 1-2 inches, you’re good to go.
  • Saddle height: With your foot on the pedal at its lowest point (6 o’clock), your leg should have only a slight bend in the knee. A good fit shouldn’t require the saddle to be at its maximum or minimum height setting for you to achieve this.
  • Reach:  How does it feel holding the handlebars while sitting on the saddle and riding? If you feel the handlebars are too far away and you need to stretch to reach them, the bike is likely too big. However, if you feel cramped and constrained with a rounded back and shoulders, you should probably size up.
  • Overall comfort:  Do you feel comfortable and confident while riding the bike? If the bike fits well, you should be able to handle and maneuver it with ease, especially when cornering and accelerating on the pedals.
  • Knee position:  Finally, if the bike fits you well, your knee should not be hitting the handlebars when pedaling. Also, the front of your foot should not be hitting the front wheel when turning the handlebars. If this happens, you need to size up.

Why sizing varies among manufacturers?

Sizing varies among manufacturers because they take different approaches to frame design, geometry, and tube measurements and angles. Brands also target different audiences and intended uses, all of which leads to sizing variations. That's why similarly sized bikes might fit riders of different heights.

What size push bike do I need?

Push bikes are typically sold with 10" - 14" wheels. A 10-inch push bike will usually fit kids aged 18 months to 2 years; a 12-inch push bike will fit kids aged 2-4 years; while a 14" push bike will typically fit kids aged 3-5 years old. These are just general recommendations—for the best fit, consider your child's inseam length.

What size bike do I need for my height?

To find out what size bike you need for your height, you should consult a sizing chart for the type of bike you're interested in, such as road, mountain, or hybrid. Depending on the type, bike size charts will match your height to a corresponding frame size denoted in centimeters, inches, or general sizes (XS, S, M, L, XL).

Is a 26-inch bike for adults?

A 26-inch bike can be suitable both for adults and for kids, depending on the context. Kids' 26-inch bikes are suitable for teenagers and shorter adults. However, some adult bikes, such as touring bikes, fat bikes or electric bikes, also come with 26-inch wheels, but these have larger frames and are not suitable for children.

What height is a 26-inch bike good for?

A kids' 26-inch bike (a bike with 26-inch wheels) is typically suitable for teenagers and shorter adults who are around 5'0" to 5'3" tall. However, bikes for adults with 26-inch wheels, such as fat bikes or some electric bikes, are often available in a few frame sizes and might fit adults who are 6 feet in height and taller.

How do I know if a bike is too big or too small?

A bike is considered too big if you cannot stand over the frame with both feet flat on the ground without the top tube touching your crotch, or if you have to stretch too far forward to reach the handlebars. Conversely, it's considered too small if you feel cramped when riding, can't adjust the seat high enough, or your knees hit the handlebars when pedaling.

___ Inch bike for what size person?

To determine which bike size is suitable for a particular height range, consult a specialized bike size chart for the bike type you're interested in, such as our road, mountain, and hybrid size charts above. These charts match rider heights with appropriate bike sizes, allowing you to get a proper fit.

And because this size is so popular, you’ll have no trouble finding accessories and components that are compatible with your bike. If you’re not sure if a 17.5 frame is right for you, always err on the side of caution and go up one size rather than down. It’s much easier to make adjustments to a bike that’s too big than one that’s too small, so better to be safe than sorry!

Trek Medium Frame Size

If you’re looking for a new bike and aren’t sure what size frame to get, never fear! We’re here to help. In this blog post, we’ll be discussing medium frames in more detail, specifically for Trek bikes. Keep reading to learn more about whether a medium frame is the right choice for you. When it comes to choosing a bike frame size, there are a few things you need to take into account. First, consider your height. If you’re on the taller side, a medium frame might be a good option for you. But if you’re shorter, you might want to go with a smaller frame. It’s all about finding what’s comfortable for YOU. Another thing to keep in mind is the type of riding you’ll be doing. If you plan on doing mostly road biking, then a lighter frame is usually best. But if you’re interested in mountain biking or other off-road activities, then a heavier duty frame might be necessary. Again, it all comes down to personal preference and what works best for YOU and your riding style. So there you have it! A few things to think about when deciding if a medium frame size is right for you. As always, we suggest coming into our store and trying out different bikes until you find the perfect fit!

Where Do I Find Frame Size on Trek Bike?

If you’re looking for the frame size on your Trek bike, there are a few places you can look. The first is on the bike itself. There should be a sticker somewhere on the frame that lists the size. If you can’t find it there, you can also look in the owner’s manual. Finally, if you still can’t find it, you can contact Trek customer service and they’ll be able to help you out.

How Do I Know My Bike Frame Size?

When it comes to finding the right size bike frame, there are a few things you need to take into account. First, your height and inseam measurement will be the biggest factor in determining what size bike frame you need. You can find your height and inseam measurements by standing against a wall barefoot with a book held between your legs, flush against your crotch. Measure from the floor to the top of the book, then measure from the top of the book to the ground again. These two numbers added together will give you your inseam measurement. Once you have these numbers, you can consult a bike sizing chart to find out what size frame will work best for you. Another thing to consider when choosing a bike frame size is whether you want a road bike or a mountain bike. Road bikes tend to have smaller frames than mountain bikes because they’re designed for speed and efficiency on paved surfaces. Mountain bikes, on the other hand, are built for rugged off-road riding and typically have larger frames that can accommodate wider tires. If you’re not sure which type of bike is right for you, it’s always best to consult with a knowledgeable salesperson at your local bicycle shop. Keep in mind that even if you choose the perfect sized frame based on your height and inseam measurements, it’s still possible to end up with a bike that’s too big or too small. That’s why it’s important to test ride any bike before you make a purchase. Pay attention to how comfortable you feel on thebike and whether or notyou can easily reach all the controls without havingto strain yourself. If everything feels good, thenyou’ve found yourselfthe perfect sized frame!

What Size Trek Bike for My Height?

When deciding on what size Trek bike to buy, your height is the most important factor to consider. Trek has a wide range of bikes that come in different frame sizes, so you’ll need to know your height in order to find the right bike for you. If you’re on the taller side, you may want to consider a Trek bike with a larger frame. For example, if you’re over 6 feet tall, you might feel more comfortable on a Trek Domane SLR 9 or Madone 9.5. If you’re closer to 5 feet tall, a smaller frame like the Trek Emonda ALR 4 or Procaliber 9.9 might be better suited for you. In general, it’s always best to err on the side of caution and go with a larger frame if you’re unsure. You can always make adjustments with the seat and handlebars to make it more comfortable for your specific height. And remember, if all else fails, there’s always the option of customizing your own Trek bike!

What Size is a 17.5 Bike Frame?

When it comes to bike frame size, the number 17.5 refers to the length of the seat tube. This measurement is taken from the center of the bottom bracket to the top of the seat tube. The average 17.5 inch bike frame will have a top tube that is also 17.5 inches long. However, some manufacturers make bikes with slightly longer or shorter top tubes. For example, a company like Specialized might make a 17.5 inch bike frame with an 18 inch top tube. The rest of the dimensions on a 17.5 inch bike frame will vary depending on the type of bike and manufacturer. For instance, mountain bikes tend to have longer chainstays than road bikes. And within each category, there can be even more variation between brands. So it’s important to look at all of the measurements when you’re trying to determine what size bike frame you need. Here are some general guidelines for sizing a bike frame: – If you’re between 4’11” and 5’3″, you’ll probably need a 13-15 inch frame – If you’re between 5’3″ and 5’7″, you’ll probably need a 15-17 inch frame – If you’re between 5’7″ and 5’11”, you’ll probably need a 17-19 inch frame

But, how to choose one if you last cycled many years ago, or never at all? As a lot of shopping has shifted to the internet, you'll likely have no option of testing the bike before you buy it. This is where we come in handy, this bike size calculator helps you estimate your biking needs. Of course, a professional fit with a bike expert would be much better, but unusual times call for extraordinary solutions .

Of course, cycling doesn't have to be everyone's cup of tea. If you prefer walking, you can use our steps to miles calculator to see how many steps you need to take to cover desired distance. Alternatively, if you happen to own a home gym, check the bench press calculator to see how your rep max improves over time!

OK, you've taken the first step - you're buying a bike. But... what now? How do you know which bike is the right one for you? To facilitate your decision, here is a short description of the three most popular bike types:

1. Road bike / Gravel bikes

Road bikes are designed for smooth surfaces, like paved roads and bike lanes. They're usually lighter than other types of bike. Their tires are narrow, and their handlebars are bent ("dropped"). Gravel bikes, a hot trend, can also handle unpaved tracks and rugged terrain.

2. Mountain bike

You should choose a mountain bike if you are looking to bike through varied or off-road terrain. Mountain bikes have flat handlebars and wide tires, while higher end models may include suspension for added grip and comfort.

3. City / trekking / hybrid bike

This category includes all other bikes. They are a compromise between mountain and racing bicycles, with a focus on comfort and low maintenance. Depending on the model's characteristics, it may be used for recreational purposes, but also commuting or errands.

Of course, there are many different bike types that we don't describe here - BMX, triathlon, folding or recumbent bikes, to name only a few. But we believe that these three types are more than enough for a first-timer (or purchasing online).

To find out your recommended bike size, you first need to measure your inseam - that is your inside leg measurement. Simply speaking, the inseam length is the distance from the floor to your crotch. So, how to measure the inseam properly?

  • Stand close to a wall , your feet should be 6-8" (15-20 cm) apart.
  • Place a large, hardcover book between your legs - it will simulate the saddle.
  • Mark where the book's spine touches the wall.
  • Measure the distance from that point to the floor - that's your inseam.

Some formulas or charts use only the rider's height, but this leads to a less accurate estimation - you can have short, long or "average" length legs. As many different formulas exist, this bike size calculator won't show you only one number, but other frame sizes which may fit.

With this bike size calculator we'd like to give you an idea which sizes of bike frames you should look at. But first we need to start with a general disclaimer - you should treat this tool as a guideline only. There are many different bike brands and models, so frames and general structure may vary a lot between them. Also, every cyclist is built slightly differently, and may have particular needs and preferences.

The frame size is usually measured as the distance between the top of the seat tube (where the seat clamp holds the seat post) and the center of the bottom bracket . Sometimes, the center or top of the top tube is chosen as the first point.

bike size for adults

Our bike size calculator determines bike frame sizes on the basis of your inseam measurement. The formulas vary for different types of bike:

1. City/trekking bike frames

Trekking frame size = inseam [cm] x 0.64

2. Road bike frames

Road frame size = inseam [cm] x 0.67

This is the formula created in the '80s by Cyrille Guimard , famous French coach and former pro cyclist.

3. Mountain bike frames

Mountain bike frames are smaller than road bike frames. Usually, a frame shorter than 4 - 5 in (10 - 12 cm) is a good start

Mountain frame size = Road frame size - 11 [cm]

You probably noticed that the formulas don't directly take your height into account. However, when you choose your height from the drop-down list, a probable range of your inseam will appear (on average, it's around 47% of your height). This bike size calculator is suitable for both men and women.

To find a child's bike size, we also take into account the length of their inseam. However, bike sizes are expressed differently for children - not by frame, but by wheel size.

bike size for kids

Before buying a bike, remember to research, think for a while, and answer these three crucial questions:

What do I need a bike for? Ask yourself what you are going to use your new bike for, and over which terrain that will take you - paved roads, gravel, or off-road? City or nature trails? You can find some hints in the Type of a bike paragraph above.

How much do I want to spend? You can not only buy a bike for $300, but also for $3000, so decide on your budget first. That leads us to the next tip...

Do I want a used or a new bike? If you'd like to buy a better quality bike that is unfortunately too expensive, you can always search for used bikes. Just be careful you are not scammed - maybe your friend wants to sell one, or a local shop has some ex-display models?

After finding the type of bike you'd like to buy (and can also afford):

Find the right size bike - our bike fit calculator will give you a hand with that. Also, checking the manufacturer's site can be helpful, as brands and models may differ, and detailed dimensions are sometimes available. Note, that some manufacturers make a distinction between men's and women's models - the difference can be as trivial as the bike's color, but it may be that the whole frame is constructed to better suit a woman's body.

Think about necessary accessories - don't spend your whole budget on the bike itself; you'll not only need to buy the essentials, like a helmet, lock, and lights, but maybe some other useful things - a water bottle holder or a repair and maintenance kit.

Customize - remember that many bike parts can be swapped. So don't cross out an almost ideal fit - maybe the parts you don't like can be quickly and cheaply removed, e.g., the handlebars or wheels?

And, if it's possible:

  • Test-ride a few different bikes . Purchasing a bike from a stationary shop has many advantages - apart from testing the bikes, you can ask for advice and recommendations. Don't hesitate to ask questions that will clear any doubts. Some shops even offer a bike-fitting service that can help you to adjust your new purchase perfectly to your body.

You can find gazillions of bike frame size charts on the Internet. The problem is that they can vary a lot . Here we propose some conservative estimates of mountain bike frames and road bike frames.

For kids' bikes, the table we've adapted looks as follows:

We hope that after reading that short article and using our bike size calculator you will no longer wonder what size of bike frame/wheel you need. If this sparked your curiosity and you want more thorough information, a great place to find it on the bike size chart by Rinasclta bike. Just remember that all of these kinds of calculation should be taken with a pinch of salt - all in all, the best method is to try on different bikes . With professional bike fitting or even a simple trial and error process, you can find the perfect bike for you.

You might have noticed that the recommended bike frame size will vary depending on the discipline you chose. This is partly because of how frames are designed, but is mostly due to the different requirements and priorities in each discipline. If your position on the bike changes, so will the bike frame size.

Let's start with mountain biking , which can be divided into several categories, but all of them have many similarities: a fairly upright position, wide handlebars and strong emphasis on comfort and bike handling. This means that a mountain bike frame will tend to be smaller than its road equivalent, allowing you to jump over obstacles and easily throw the bike around when riding " the gnarl ".

On the opposite side of the spectrum we find road bikes . These too can be separated into many categories with "endurance" machines in the comfy end and "Time Trial (TT)" bikes on the performance end. In general, though, the smoother surfaces, higher speeds, and narrower handlebars favour for a more stretched position, with a larger distance between the saddle and handlebar.

However, keep in mind that these are only general remarks, with new developments and trends appearing constantly. Cutting-edge bikes might not follow these rules. Right now, road bikes are doubling down on the aerodynamic benefits of going low, narrow and stretched out. Mountain bikes (especially enduro and do-all machines) are getting longer, lower and slacker with every new model despite the humongously wide bars we tend to see fitted.

Don't try to fit your bike, make your bike fit you

As a final note, it is important to remember that it is the bike that needs to fit you , and not the other way around. This is particularly important when one size of frame is designed to suit different people. So, once you get the right frame size, remember to check and tune everything to fit your body.

The first and most natural thing to do here is to adjust the seat post height so that your leg is extended at the bottom of the pedal stroke, while keeping a slight bend to your knee. This ensures optimal power output and prevents knee problems , with the only trade-off being that you probably cannot reach the ground with your feet while seated in the saddle.

The next step is to think about the position of your stem, the size of your stem, handlebars, cranks... and even saddle position within the seat post. The options here are almost limitless if we take into account that swapping parts is generally inexpensive and can totally transform your fit.

As always, the recommended way to go about fitting a bike to your body is to get a professional bike-fit. However, it may be very costly for most people, so the next best option is to go by feel and adjust things if you experience pain or discomfort after riding your bike. This is generally more than enough for everyone but the most committed amateur and professional cyclists, so try it yourself and find the perfect fit for you!

What size bike should I get?

We’ve compiled an extensive guide to bike sizing that makes figuring out the right size a whole lot easier. Below you’ll find great info on how different bikes are sized and how to find the best fit for men, women, and kids.

How do you figure out your bike size?

Bike sizing can be a bit of a pain sometimes because there isn't always one universal system of measurement that’s the same for all types of bikes and all riders.

Depending on whether you’re looking for an adult bike, a kid’s bike, a road bike, or a mountain bike, you’ll need to find out what your frame size or wheel size is. 

We always recommend heading into your local bike shop to get the best possible fit, but you can also you the size charts and information in this guide to find the size that's best for you.

family riding bikes

Adult bike sizing vs kid bike sizing

In a nutshell, adult bikes are sized by the frame, and kids bikes are sized by the wheel.

That means that there are two completely different measurement systems between adult and kids bikes. As children grow they’ll obviously start to fit on small adult bikes, but generally, kids 12 and younger will fit on bikes that are measured by the size of the wheels.

woman riding bike

Women’s bike sizing

While some companies offer women-specific models with designs that aim to incorporate better-fitting components, there is no substantial difference between men’s and women’s bike sizes. Both women and men can use the same adult bike size charts below to find a great fit.

To make matters a little more confusing, sizing can also vary between styles of bike or the company that makes them. For example, road bikes and mountain bikes will often use different numbers to designate sizes.

Without going into too much detail, bike size used to be determined by measuring specific parts of the bike, like the seat tube. However, over time manufacturers have decided to update their measurement system since bike geometries have changed considerably. The goal was actually to make it easier for people, but since some companies still stick with the old systems, it can be a bit puzzling.

In the sections below we have broken down a few size charts for road bikes, mountain bikes, hybrid bikes, and kids bikes. It’s important to note that there is no single bike size chart that is universal to all brands or styles. Many bike manufacturers differ slightly in their sizing, but the charts below will give you a good idea of where to start.

Road Bike Size Chart

Road bikes will often use measurements in centimeters to denote frame sizes. If you’re looking at a road bike and you don’t know what size it is, start by measuring the seat tube, as that will give you a good ballpark idea.

Shop Road Bikes

Are you in between road bike sizes on our chart and unsure which way to go? Here are some points to consider:

Size up on a road bike if:

  • you have long arms (your wingspan is larger than your height)

Size down on a road bike if:

  • if you're mostly concerned with having a bike that's lighter and stiffer (sprinters)
  • if you prefer an upright riding position

Mountain Bike Size Chart

Mountain bikes will either be measured in inches or, more likely, in a consumer-friendly Small/Medium/Large hierarchy. Newer mountain bikes can be tough to size without the help of a sticker or stamp on the frame, as geometries have changed so much in recent years that measuring tubes won’t typically give you very good insights.

Shop Mountain Bikes

When choosing the wheel size for your next mountain bike, you'll want to take your height and your preferred riding style into account. It's true that smaller riders often feel more in control on smaller wheels, but depending on your level of experience and the desired ride characteristics, that may or may not be the best way to go for your specific goals. 

If you're a beginner, go with the first option on the suggested wheel size portion of the above chart. If you're an advanced rider, you might consider the other listed option and decide which wheel size will suit your riding style best.

As a rule of thumb, larger wheels have faster top speeds and roll over obstacles easier, while smaller wheels are more maneuverable and "playful". If your trail priorities are speed and efficiency, go with a larger wheel size. If your priorities are agility and playfulness, you might really enjoy a smaller wheel size.

Trek recommends riders go with the largest wheel size they can comfortable handle. We'd add to that by saying the best way to get a feel for what's comfortable for you is to come test ride a bike!

Are you in between mountain bike sizes on our chart and unsure which way to go? Here are some points to consider:

Size up on a mountain bike if:

  • you're a more aggressive rider who appreciates a longer reach
  • you prefer stability on descents to maneuverability
  • you like to ride over and through obstacles rather than around them
  • your wing span is greater than your height
  • you are flexible and better at maneuvering your body to adjust to terrain

Size down on a mountain bike if:

  • you prefer to ride more upright
  • you riding style is more conservative than aggressive
  • you prefer maneuverability over monster truck-like plowing power
  • you are less flexible and tend to ride in a similar position

It's important to point out again that not all manufacturers use the same frame size naming conventions. Some brands prefer to "simplify" their sizing to numbers from 1 - 6 (instead of XS - XL) for example. The thing to keep in mind is that not all brands are sized the same, and it's important to look at the size charts provided by the brand you're looking at, as well as the bike's geometry chart, in order to get the best fit.

In the early days of mountain biking, we used to size MTBs by the lengths of their seat tubes, as that would give someone a pretty good idea of what the standover height for a bike would be. That worked for a while, when frame design was relatively straightforward with top tubes and geometry that were more similar to road bikes.

As mountain bike design evolved, manufacturers were able to find more capable performance with different tube lengths and angles. With longer, more sloped top tubes and dropper post-ready designs (and more variations across brands), the seat tube is no longer the best way to approximate a bike's size. This paved the way for brands to start their own sizing methods.

Hybrid Bike Size Chart

Hybrid bikes like commuters and fitness bikes are great all-arounders that are extremely versatile and often very affordable. Most hybrid bikes use a Small/Medium/Large measurement system, but you might find a few companies who still use inches as the size denotation.

Shop Hybrid Bikes

Go with the larger size if:

  • you have long arms (an arm span that's longer than your height) or long legs
  • the larger size has larger wheels and you prefer larger wheels

Go with the smaller size if:

  • you have a longer torso but an average or shorter arm span/inseam
  • you have bad hips or a bad back or other mobility issues

Kids Bike Size Chart

As we stated above, kids bikes are measured by the size of their wheels, and it’s much more straightforward than adult sizing. A 12-inch bike has 12-inch wheels, a 16-inch bike has 16-inch wheels, and so on. Here is a great general kids bike size chart to get started, but it’s always best to have your child try a bike before you buy it.

What to do if your child is in between kids bike sizes

Go for the larger size if:

  • they feel confident on the bigger size
  • they're getting into racing or biking as a sport

Go for the smaller size if:

  • they're less confident riders

It's almost always better to size up with kids bikes, but only if they can actually handle the larger size. Kids grow up fast, and as a parent you'll want to try to give them a bike that they can ride for at least a few years, not just one.

There are some exceptions, though. Go too big and they may not be able to control the bike, which is more dangerous and certainly less fun. Kids will become better riders when they're riding a bike they feel confident on.

How to check if a bike is the right size

Let’s say you’re standing in front of a bike that you’re interested in buying and you even know what size bike it is. According to all the size charts, the bike should be about right, but how do you know for sure? And what if you’re right on the line between two sizes? Read on to learn some of the most important things to consider when looking for the perfect fit.

Important:  getting the right fit on a bike is just as important as choosing the right size frame. If you're feeling unsure or experience pain when you ride, you should consider brining your bike to a shop. The Bike Shoppe can help! Explore our bike fitting services .

Standover height is essentially the distance between the top tube and the ground at the point where you stand over the bar. This is an important measurement to get right because you’ll want some space between your groin and the bar when you hop off the seat. For most bikes you’ll want an inch or more of standover room for a super comfortable fit. You can easily test this by pulling the bike up until it touches your body when you’re standing. If you can pull the wheels up an inch or more, you should have plenty of space.

After you’ve made sure you have enough standover room, you’ll want to make sure your legs have the proper amount of extension. You can adjust the seat height to get the right fit, but if you’ve jacked the seatpost up to the max and your legs are still very bent when you pedal, you might need a bigger size.

Here’s how to get proper leg extension:

On the downstroke, or when the pedal is closest to the ground, you should look to have around a 15-20° bend in your knee. Depending on the person you may prefer more or less bend, but you want to avoid having your knees come up too high when you pedal, which is uncomfortable, inefficient, and bad for your joints.

Another way to check your leg extension is to put your foot on the pedal and see if you can lower your heel below the axle of the pedal on the downstroke. If you can push your heel a little further than the axle, that’s often an optimum position in terms of efficiency and comfort.

Reach is pretty much what it sounds like. Specifically, the official reach measurement is usually the horizontal distance between the bottom bracket and the head tube. More generally, it translates to how far you have to reach to grab the handlebars.

Reach is something to consider mostly when you’re an experienced rider and you’re in between two sizes. Selecting a bike with a longer reach will feel “roomier”, more stable at speed, and generally more confident on technical terrain. A shorter reach will help the bike feel more responsive, but depending on what kind of riding you do, that may or may not be what you’re after.

What size bicycle is right for my height?  

Before you think about what size bike you are, you’ll want to decide what kind of bike you want. As we state in the article above, road bikes and mountain bikes often use a different sizing system, so figure out what style you’re looking for first, then consult the charts above.

Should your feet touch the ground on a bike?   

Ideally you should be able to touch your toes to the ground when sitting on the seat, but if you can put your feet flat on the ground it often means that your seat height is too low. If your seat is too low, your knees will be overly bent when pedaling and that can cause discomfort and joint pain, not to mention it’s not a very efficient way to ride.

If you feel more comfortable with your feet flat on the ground, check out Electra bikes. They use something called Flat Foot Technology which is a frame design where the pedals are moved forward on the frame so you can get proper leg extension while pedaling but still put your feet flat on the ground when you want to.

Do I need a 26 or 29 bike?  

26-inch wheels were the mountain bike standard in the past, but most mid and upper tier mountain bikes you’ll see on the market today use either 29-inch wheels or the slightly smaller 27.5-inch wheels. 29ers and 27.5+ bikes have faster top speeds and roll over obstacles easier than 26-inch wheels, so if you want to ride off-road, you’ll appreciate bigger tires. 26-inch wheels are often great for kids who have graduated from their 24-inch kids bike but aren’t quite big enough to use the bigger wheels found on most adult bikes.

What size bike does a ____ year old need?

What size is a 26 inch bike.

The 26 in a 26 inch bike refers to the wheel size, so that measurement isn’t always the best way to judge how big a bike is. Some youth bikes are measured by this wheel size, but more commonly you’ll find 26-inch wheels on a variety of adult frame sizes.

Shop 26-inch bikes

Is a 26 inch bike for adults? 

In short, yes! 26-inch wheels are used on adult bikes and have been for years. That being said, most modern mountain bikes have switched to 27.5” and 29” inch wheels for their superior speed, traction, and rollover power. However, 26 inch wheels are super strong and universally available, so bike tourers often use them for traveling abroad.

Bike Sizing Guide: What Size Trek Bike Do I Need?

Written by  Gary Johnson / Fact checked by  Henry Speciale

what size trek bike do i need

Are you looking for a bike to buy and asking yourself “what size Trek bike do I need?”

Trek bike sizing is very straightforward and varies by type.

For example, mountain bikes follow a unique method called alpha sizing that uses designations such as small, medium, or large. Using this system, a 5’3” to 5’7” tall person can use a 17.5” frame size.

On the other hand, Trek road bike sizing takes into account the inseam length.

If you want to get on the road or hit that trail with your ideal two-wheeler, check out our sizing guides below.

Trek bikes are comfortable and easy to ride, making them excellent for beginners. They also come in different dimensions, so you should find one that fits you perfectly.

Whether in inches or cm, our Trek bike size chart will help you match your height with the appropriate vehicle.

trek-moutain-bike-size-chart

Unlike other brands, Trek bikes have upgraded their MTB sizing with alpha classifications to remove guesswork for customers.

You may find that your chosen model has some and not all of the sizes in this Trek MTB size chart. In that case, branch out and look for XS and XXL options if the Trek M/L frame size doesn’t fit you.

Note that the women’s bike size chart also uses the alpha sizing guide for their line of women’s mountain bikes though the height requirement is slightly different for each size.

Did You Know

The Trek Marlin 5, which is a popular trail mountain bike, uses the alpha sizing chart, but its size is not limited to XS – XXL only! Trek also offers an XXS with 26” wheels for this MTB type.

Trek has given us 4 categories when it comes to road bicycles. These include:

  • Aero – The best aerodynamics for speed and performance
  • Endurance – Provides comfort perfect for long hours of riding
  • Time Trial – Speed-focused bikes with unique designs
  • Climbing – Lightweight bikes excellent for uphill climbing

Designed to be a mixture of road and mountain bikes, Trek hybrid bicycles are best used for casual rides and commutes.

What size bike should I get? What does “size” really mean? And what is the best way to find the correct model for yourself?

There are usually FOUR different aspects that you must consider and have a good idea about.

Riding Style

trek-bike-sizing

Do you want to ride your bike for fun or use it for racing and exhibition? Regardless of your budget, it is important that you consider the type of biking you want to do. Some people prefer to ride in the city, while others prefer to cycle off-road.

Trek bikes come in various sizes depending on the vehicle’s discipline, since some frames have different geometry to provide the support their riders need.

Rider Height

trek-frame-size-chart

Most bicycle models come in different sizes for different body types so that they fit most people well.

The height of a person, when measured from head to toe, can help determine the bike size that would match them. This is because taller people have longer upper and lower extremities compared to shorter people, which means they will need different sizes of bikes in order to ride comfortably.

Inseam Length

trek-marlin-5

After careful deliberation with the above two factors, the frame size is then ultimately determined by your inseams or the distance from your crotch to the bottom of your leg.

You should take this into consideration because it will determine how much room there is between your feet and handlebars when sitting on the saddle comfortably.

Practical Use /Test Ride

trek-mountain-bike

Last but not least, once you have chosen your bicycle size and Trek model, test out the bike with at least a short ride. This will let you assess the balance and comfort of the chosen vehicle.

Whether you ride recreationally or professionally, you cannot choose blindly. First, bikes are expensive, and second, you must buy the correct product to use it for a long time.

trek-road-bike

If you’re done with our Trek frame size chart, Trek’s online website also has a unique feature that helps you select the correct frame size. You can try their bike finder, which asks for your riding style, height, and even inseams before arriving at a recommendation.

In case you haven’t noticed, there is a lot of variation in bicycle sizing, and looking for the size I need for my height was not a walk in the park.

Well, I hope our guide answered your question about what size Trek bike do I need. Should you have any more questions, send us a message.

Overview of Trek Gravel Bike

Trek Gravel Bike is your ideal companion for off-road adventures and may even prove to be a game-changer for your outdoor workouts. But to enjoy the full benefits of this beast, you have to nail down one thing: getting the right size.

Why finding the right size for your trek gravel bike is important

First off, your comfort is at stake! Riding a bike that’s too large or too small can cause awkward body positions, discomfort, and even injury. Sizing matters not just for comfort, but your performance as well. A properly sized bike boosts your efficiency and control, which is especially crucial on rugged terrains that trek gravel bikes are built for.

To assist with accurate sizing, Trek provides a detailed size guide that factors in your height and other considerations. Before buying, compare your personal measurements with their chart, or better yet, go for a test ride! After all, it’s about attaining harmony between you and the bike.

Understanding Trek Gravel Bike Sizing

When it comes to finding the perfect fit, a Trek gravel bike is as comfortable as it gets. Let’s delve deeper into how to choose the right size.

Factors to consider when choosing the correct size for your Trek gravel bike

Bike size is a crucial aspect to think about. It’s not just about your height but also your inner leg length, reach, fitness level and the type of riding you’ll be doing.

For Trek gravel bikes , frame size ranges from 49cm to 62cm, generally speaking. Here’s a helpful guide: if you’re 5’3″-5’6″, go for a 50-52 cm frame; people of 5’6″-5’9″ will likely fit a 54-56cm frame. However, it’s always ideal to test ride before settling.

The bike’s geometry factors greatly in riding comfort and efficiency. Trek’s gravel bikes are designed for comfort during long rides, with features like a more upright riding posture.

Reach and stack measurements

Finally, keep an eye on reach and stack measurements too. ‘Reach’ determines how stretched out on the bike you’ll be while ‘stack’ is the distance from the middle of the bottom bracket to the top of the head tube which affects your riding position. Optimizing these measurements can enhance your riding experience.

Trek Gravel Bike Size Chart

When venturing into gravel bike territory, your adventures must come with the assurance of a perfect fit. Let’s help you choose the right Trek gravel bike size, and kick-start your journey on a good note.

A detailed size chart for Trek gravel bikes

Trek provides a comprehensive size guide for their gravel bikes, which details the rider’s height against the appropriate bike size.

Men’s sizes

For men, bike sizes range from small (suitable for heights from 5’3”-5’6”), medium (5’6”-5’9”), large (5’9”-6’2”), to extra-large (6’2”- and above).

Women’s sizes

On the other hand, women’s sizes typically begin from extra small (suitable for heights below 5’3”), with small (5’3”-5’6”), medium (5’6”-5’9”) following closely, before capping at large size (5’9” and above).

Take note , these numbers are a guide and personal comfort and riding style should prevail when making your final decision.

Armed with this size guide, you’re ready to conquer any trail on your Trek gravel bike. Here’s to thrilling rides!

How to Measure Yourself for a Trek Gravel Bike

If you are passionate about gravel biking and thinking of buying yourself a Trek Gravel Bike, it’s paramount to get the right size. As an off-road enthusiast, comfort and fit are your most important prerequisites.

Step-by-step guide on Measuring your inseam , arm length, and torso length

Measuring your inseam: Stand upright with your back against the wall. Place a book between your legs, with its edge against the wall. Measure the distance from the floor to the book top – that’s your inseam.

Arm and torso length: Extend your arm to your side, level with your shoulder. Measure the distance from your shoulder to wrist – arm length. For torso length, measure from your collarbone to the top of your inseam.

Tools needed for accurate measurements

To get these measurements, you will need a measuring tape and a book. See? It’s easy – no professional skills needed! Now all that’s left is to pick the perfect Trek Gravel Bike that suits your measurements. Enjoy your ride!

Choosing the Right Trek Gravel Bike Size

Embarking on a gravel biking adventure can be thrilling, especially with the dependable Trek bikes. However, it is important to find the right bike size to ensure a comfortable and safe ride.

Using the size chart and your measurements to determine the ideal size for your Trek gravel bike

Choosing the perfect bike is best determined by your physical measurements. To do this, consider the inseam and your height. Trek’s size chart can be quite useful for this. While using the chart, remember that sizes may vary across models, and thus, the chart serves as a general guide.

For your inseam : Stand with your shoes off and feet shoulder-width apart, measure the distance from the ground to your crotch. The result will guide you in identifying a suitable frame size.

For your height : Measure your height and cross-check with Trek’s recommended rider height against each bike size.

Consider trying different sizes if you’re in-between the recommended sizes. Ultimately, comfort is paramount, and ultimately the right Trek gravel bike size should feel ‘right’ to you, both while standing over it and while pedaling.

Adjustments and Customizations

Ever thought of riding your Trek gravel bike with the most comfort and the least strain? Then understanding how to properly adjust and customize your bike will bring about a noticeable improvement to your cycling experience.

Fine-tuning your Trek gravel bike fit with adjustable components such as stem length and saddle position

No doubt, the stem length plays a significant role in your ride comfort. Adjusting it with a shorter or longer stem can either bring the handlebars closer or push them further. You may want it closer for an upright, relaxed position, especially for casual rides. Conversely, if you’re name-dropping on gravel biking adventures, a longer stem puts you in a more forward, aggressive position for better bike control.

The saddle position is another adjustable component that affects your ride. Nudging it forward might allow for stronger pedaling, the better the hill-climbing, while a backwards adjustment usually offers more cruising comfortability.

However, remember, before embarking on a bike fit experiment, it’s crucial you’re educated on the directions to go. If unsure, consulting a professional bike fitter might be best to avoid any potential damage or injury. In the end, the ultimate goal is to enjoy your ride!

Trying Before Buying

Whether you’re a seasoned cyclist or just starting, the fit of your gravel bike plays a crucial role in your riding comfort and performance. At the core of the perfect fit is the ideal bike size.

The importance of test riding different sizes and models before making a purchase decision

Choosing a Trek gravel bike isn’t merely about picking one that looks appealing. It’s about getting the right mix of comfort, ease, and performance. Here is where the magic of test rides comes in. Ready to dive in?

Test riding different sizes: There is no one-size-fits-all when it comes to bikes. Your height, inseam length, and other body measurements blended with the type of riding you plan to do will determine the perfect bike size. You wouldn’t wear shoes that don’t fit, right? The same applies to your bike. Test riding different sizes enables you to feel the difference and find a bike that feels right.

Exploring various models: Even within the same size class, different models can provide varied feel and performance. Test riding various Trek gravel models will help you understand how the bike geometry, component choices, and other design nuances impact your experience.

Remember, it is about the ride, not merely the aesthetic or price tag. Your comfort and enjoyment on a Trek gravel bike will heavily depend on the optimal bike size and model, so take your time to test ride, compare and eventually make a well-informed purchase. It’s an exciting journey to embark on!

Common Mistakes to Avoid

When it comes to choosing the right Trek gravel bike size , it can be an exciting yet daunting process. But fear not! You’re in the right place to avoid common pitfalls and make the selection process smooth.

Mistakes to avoid when selecting the size for your Trek gravel bike

In your quest or the ideal gravel bike, remember each one of them come in different sizes and designs. Falling prey to generalisations or misconceptions about bike sizing can set you up for a disappointing ride.

Overestimating or underestimating your measurements

The accurate way to roll is to know your measurements well. While the inclination towards a larger frame because it’s seemingly ‘better’ or being biased towards a smaller frame for its ‘lightness’ is common, it’s imperative that your bike size matches your body dimension for comfy and efficient rides.

Ignoring the importance of proper bike fit

Lastly, don’t overlook bike fit. A well-fit bike takes into account your height, inseam length, and riding style, which are crucial for your cycling performance, comfort and safety. Neglecting these aspects could lead to a disappointing cycling experience, or worse, lead to injuries. Thus, always seek professional help or utilize online bicycle sizing resources if you’re new to this.

FAQs about Trek Gravel Bike Sizing

You’re probably excited about the prospect of getting your hands on a Trek gravel bike, but you might be wondering about the right size for you. Don’t worry, we got you covered!

Commonly asked questions about finding the right size for a Trek gravel bike

Where do I start with sizing? Start with your height. Trek bikes come in different frame sizes, correlating with your height range.

What if I’m in-between sizes? If you happen to fall between sizes, it’s generally safe to go for the smaller size. Remember, it’s easier to adjust a slightly smaller bike to fit you than a larger one.

How to ensure the perfect fit? Always do a ‘standover’ test. This means you should be able to stand over your bike with a small clearance between you and the top tube.

Why the right size matters? Finding the right size of your Trek gravel bike means increased comfort, better control, less risk of injury, and a more enjoyable ride. Enjoy your biking adventure and remember, choosing the right size is key to your overall biking experience !

Taking the time to find the correct size for your Trek gravel bike ensures comfort, performance, and an enjoyable riding experience

When it comes to choosing the right size for your Trek gravel bike, it’s important to consider your height, inseam measurement, and riding style. By following a few simple guidelines, you can find the perfect fit that offers optimal comfort, performance, and an enjoyable riding experience.

First, determine your height using a measuring tape or by checking an accurate measurement from your healthcare provider. Then, refer to the Trek gravel bike sizing chart to find the size range that corresponds to your height.

Next, measure your inseam, which is the distance from your crotch to the floor. This measurement will help you determine the appropriate standover height for your bike.

Lastly, consider your riding style and preferences. Are you more comfortable with a more upright position or do you prefer a more aggressive, forward-leaning stance? This will help you determine the right frame size and geometry for your needs.

Taking the time to find the correct size for your Trek gravel bike is worth the effort. It will ensure that you can ride comfortably, efficiently, and enjoy every adventure on your new bike. Happy riding!

Genesis unveils stunning first luxury full-size electric SUV with the Neolun Concept

Avatar for Peter Johnson

Genesis made a bold statement unveiling two stunning new luxury EVs. Among them was its first full-size luxury electric SUV concept, the Genesis Neolun Concept. Meanwhile, Genesis is previewing a new high-performance brand set to rival Mercedes-AMG with the GV60 Magma concept.

Hyundai’s luxury brand Genesis is making a name for itself in the EV era. After nearly quadrupling EV sales in the US last year (topping Lexus and Lucid), Genesis looks to continue its expansion.

As one of the first legacy automakers to commit to ending gas-powered vehicle sales by 2026, Genesis is making quick progress. Genesis launched its first EV in the US, the GV60, in May 2022.

Since then, the luxury brand has added the Electrified GV70 and Electrified G80 sedan. The Electrified GV70 marked the first Genesis (and Hyundai) EV built in the US, rolling off the production line over a year ago.

According to data from Cox Automotive , Genesis sold 6,403 EVs in the US in 2023, up 283% from the 1,671 delivered in 2022.

Genesis added a cheaper Electrified G80 “Advanced” trim that’s $5,380 less than the previous year’s model. The Genesis G80 now starts at $75,570.

Genesis Neolun previews first full-size electric SUV

Ahead of the NY Auto Show, Genesis revealed the Neolun concept , previewing its first full-size luxury electric SUV.

The electric SUV will serve as the brand’s tech beacon with “innovation that exceeds conventional standards,” according to Genesis.

Genesis-Neolun-Concept

“It’s the epitome of timeless design and sophisticated craftsmanship,” according to Genesis Chief Creative Officer Luc Donckerwolke. The name “Neolun” comes from the Greek “neo,” or new, and Latin “luna,” meaning moon.

Donckerwolke explained that “The Neolun Concept was inspired by Korea’s iconic moon-shaped porcelain jars.”

Genesis-Neolun-Concept

The electric SUV exterior is based on a “reductive design” with clean lines and no unnecessary details. Genesis included coach doors, removing the B-pillars, and connecting the vehicle’s body and roof.

The design provides a spacious interior. Meanwhile, electric side steps automatically deploy when the doors open.

Genesis-Neolun-Concept

Inspired by Korea’s “ondol,” the Genesis Neolun concept includes a radiant heating system for efficient heating through the vehicle, similar to a Korean home heating method.

The electric SUV features an advanced “sound architecture” for an immersive audio experience. Genesis claims each speaker is strategically placed to provide a “concert hall-like” feel. As the speaker activities, the crystal sphere upfront rotates into a tweeter.

Genesis GV60 Magma previews high-performance brand

Genesis also unveiled the GV60 Magma, officially kicking off the brand’s entry into high performance.

After teaming up with racing legend Jacky Ickx, a sportier GV60 appeared in the background of an intro video. We speculated it could be the new GV60 design .

Genesis-GV60-Magma

It looks like it was more than that. Genesis officially launched Magma, the luxury brand’s new high-performance brand. Genesis Magma is “the brand’s expansion into the realm of high-performance vehicles.”

“Genesis Magma presents an exciting opportunity to push the boundaries of performance and luxury for new interpretations in high-performance vehicles,” Donckerwolke boasted.

Genesis-GV60-Magma

The Genesis GV60 Magma will be among the first models to launch. Taking the brand’s first dedicated EV, the GV60 Magma, is lower and wider for a sportier design and lower center of gravity.

Top comment by Rob Andrews

Hyundai and Kia are putting nails in the coffins of Japanese autos. It is not large numbers yet, but over time and each new generation of vehicles, Japan falls further behind. As the software matures and NACS becomes standard on all Kia/Hyundai EVs. I can see Toyota, Honda and Suburu losing market share as Hyundai and Kia increase their EV sales 10X in the next 2-3 years.

Genesis included a wider and lower air intake in the bumper to cool the batteries and motor. Three stamped holes above the main air intake provide additional cooling with added canards for downforce. Fins have been added to the roof to channel air to the rear wing, generating downforce.

Genesis-GV60-Magma

The luxurious and sporty interior includes bucket seats with double-diamond stitching patterns featuring Magma’s iconic orange and titanium grey colors.

Genesis’ new high-performance brand will rival Mercedes-AMG, which teased its first sporty electric vehicle testing earlier this month.

What do you guys think about Genesis’s new EV concepts? I look forward to seeing more about the luxury brands’ new EV projects. Let us know your thoughts in the comments.
