Found the perfect bike but puzzled by complex sizing? We're here to help with the following guide. All you need is your height in feet & inches (1" = 2.54cm, 12" = 1') & your inside leg measurement in inches & we'll help you pick the right size.
Bike geometry - The essential knowledge
Geometries vary based on intended use & manufacturer preferences, most of the figures define the ride & handling characteristics of the bike. The main figures you need to consider when choosing a size are:
- Seat tube length/frame size
- Top tube length
- Standover height
Specialist use mountain bikes such as downhill, dirt jump, BMX & 4X are sized to be smaller in proportion to the rider & often come in short, medium or long sizes.
How to find the correct frame size
Manufacturer recommendations are based on your height with an assumed "standard" inside leg. If your inside leg is outside of the assumed range, you may be required to adjust the size of frame accordingly. Use the table below to match your measurements with the most common mountain bike sizes.

Checking standover clearance
Standover clearance is essential to prevent injury during a fast dismount. You should allow at least 1"-2" of clearance, for full suspension bikes this figure should be slightly more.
To work out the standover clearance just minus the standover measurement (found on the details tab of product descriptions or on the manufacturers website) from your inside leg measurement. If there is not enough clearance, consider going down a size.
Tips & tricks for getting the perfect fit
If you find yourself sitting between sizes or have recently purchases a slightly wrong sized bike there are a few tricks to help tweak the fit of the bike. You can try some of the following ideas:
- Moving the saddle on it's rails
- Fitting a longer/shorter stem
- Changing handlebar position
