Finding the right frame size

Before you can find the right bike frame (and not the height), you'll need to determine your inseam

To determining the inseam length, follow these easy steps:


Required Materials:

- A yardstick or a measuring tape.

- A book, writing pad, cutting board or something similar.


Step 1

Stand on level ground with no shoes on. You can stand up against a wall for more accurate results.


Step 2

Take the book/block/pad/etc, put between legs and push it upwards as far as comfortably possible.


Step 3

Measure the distance from the top of the boom/block/pad to the floor using the yardstcik or measuring tape. The resulting number is your inseam length.

Size matters.

The tables below show the frame size that best suits your height. The deciding factor for the size of a bicycle is the frame - in particular, the seat post (the distance from the center of the bottom bracket to the top of the seat post). The sizes are measured in inches (MTB) or centimeters. You may find both units in the description of the bike.

Kid's Bikes

For adult bikes, the size of the bike is determined by the size of the frame. For kid's bikes, the sizes - which usually start at 10 inches - refer to the size of kid's bike. You'll find recommended sizing based on age in the descriptions of the bikes. However, it's important to remember height is a factor in sizing, so these ages should be used as rough guidelines.

A kid's bike is also reasonably flexible in size. You can adjust the saddle and the handlebars in height, so the bike can fit and grow as your child grows.

Important To Note

Because everyone is different, the values ​​in our tables should only be used as a general guideline. For example, despite women and men having different body proportions, the frame sizes are the same for men's bikes and women's bikes. What differs is the frame geometry. In most cases, the length of the top tube is shorter for women's bikes (i.e. the distance from the saddle to the handlebar is smaller). This fits the female anatomy better, thus possibly making the women's bike more comfortable for women to ride. But the aspect ratio between arms, legs and torso is different for everyone. This means there are bikes for people with long arms, short arms, long legs but short upper body, etc. Additionally, the size of the wheels is a huge factor in bike sizing, because the bigger the wheels are, the higher the bike. Our tip: if you are reluctant to get on your bike and your old bike seems uncomfortable, measure the frame height and compare it with your body size.

Are You Between Two Bike Sizes?

If you are exactly between two sizes, no worries! Bikes vary in frame geometry - it depends on the type of bike and/or manufacturer. This allows you to find a bike with the best fitting frame size for you. Also, saddles and handlebars are also height adjustable for adult bikes, so you can customize your bike. Many bikes have an adjustable stem, so you can change the angle of the handlebars until the bike fits comfortably. Lastly, the frame size can influence the driving characteristics, so you can choose the smaller or larger frame depending on the driving style. A smaller frame is generally more maneuverable and agile. A larger frame distinguishes the bike through a quiet and stable road handling, perfect for long journeys. General rule of thumb: the more time you want to spend on your bike, the more accurate you'll want the fit. In addition, you have to pay attention to the fit. If you'll be riding off-road, a wrong bike could be a real health risk!
