The Proper Bicycle Frame Size

Want to calculate the correct bicycle frame size for your body size? The frame size is measured from the seat lug at the top to the center of the bottom bracket. If you divide your height by three, or subtract 9 inches from your inseam length, you'll get your proper frame size.

*While you can compensate for a smaller frame with a higher seat and headset, you should never make do with a too large frame that doesn't allow adequate groin clearance when straddling the bike – the consequences are much too painful.
