Bike Sizing Guide: Determine Your Dimensions
We need three personal measurements to help fit a new bike; leg, arm, and the clavicle notch to the floor. You’ll need an assistant to measure—and, for accuracy, perform each one a couple times then average their results.
|First measurement: Leg Length||Second measurement: Clavicle Notch to the floor||Third measurement: Arm Length|
Measure from the floor to the crotch. This is NOT the same inseam as your trusty denim. It’s a good idea to wear riding shorts/chamois for a more accurate result. Grab a hardback book, or that cherished bicycle themed VHS you keep hanging around. Anything that has square edges, with which you can straddle. Stand against a wall—with a hard, flat floor—feet shoulder width apart (no shoes on). Pull the square-edged device up into the crotch, it should be the same pressure as if you’re sitting on a saddle. Use the wall to keep it perpendicular to the floor. You can now measure from the square to the floor. Also mark the wall, and measure that as well. Write these down and average the two.
With the back still against the wall, now find your Clavicle notch. It’s the V-shaped notch between the clavicle bones just above the sternum. Measure from here to the floor, write it down, repeat measurement, and average.
Now measure from the shoulder pivot to the center of a gripped object. Hold your arm at a 45 degree angle from the body, measure from the shoulder pivot to the center of an object gripped, perpendicular to your arm. The object should be about the diameter of a handlebar, like a roll or quarters. Repeat for the other arm, then do it all over again and average the results.
