Bike Fit Measurements

The measurements we are asking you to provide for us below are used by our fit experts to help determine the appropriate size for your frame and components.

For best results, print this page out and have someone help you measure. Things you will need: a tape measure, a pen/pencil, and a hardcover book with about a 1 inch binding.

Measurements: All measurements should be taken without shoes, standing straight, and feet about 8 inches apart (about shoulder width).


Height: Stand with your heels and buttocks against the wall. Measure from the ground to the top of your head.

Your Height is ___ inches or ___ centimeters


Sternum Notch: This measurement is used to determine your torso length and the optimal rider “cockpit” size. Stand with your heels and buttocks against the wall. Measure from the ground to the sternum notch (between the two bony protrusions at the base of your throat).

Your Sternum Notch is ___ inches or ___ centimeters


Inseam: The accuracy of this measurement is critical to the sizing of your frame. You can fine tune a fit with different stems, seatposts, or handlebars, but a good fit starts in the correct frame. Please be aware that your inseam or leg length measurement is NOT the same as your pant inseam. Stand with your heels and buttocks against a wall. Place a book between your legs and firmly against the wall. Pull the book up into your crotch very snug, like when sitting on a bike saddle. The book should sit firmly against the wall. Measure from the ground to the top edge of the book.

Your Inseam is ___ inches or ___ centimeters


Arm Length: This measurement helps to determine the rider’s “cockpit” (roughly the distance from your seated saddle position to the handlebars). Getting the right cockpit means that you are neither cramped nor stretched on the bike. Measure in a straight line from the inside of your armpit (just touching your body) to the point where your thumb and index finger form a "V"

Your Arm Length is ___ inches or ___ centimeters


Shoulder: This measurement helps determine your handlebar width. Measure your shoulder width by the outside of the bony points at the top of your shoulders or, if it is easier, measure from the inside of one armpit to the inside of the other.

Your Shoulder is ___ inches or ___ centimeters
