Standover Height This is the height at which you can stand over the frame without touching it. A lower standover height allows for easier mounting and dismounting. Choosing the Right Size 1. Frame Height A general rule of thumb is to measure your inseam. When standing beside the bike, you should have about 2-4 inches of clearance between the top tube and your crotch. For those with a shorter inseam, look for bikes with a smaller frame.
