This is General Size Chart, which should be helpful to find proper frame size of the bike. The most important factor is Inside Leg size. Wrong measuring may lead to the wrong frame size. So here is few tips: The best way to do it is to undress (baggy or wide cut trousers, shoes cause mistakes!) and find the highest possible crotch position. For this purpose you can use spirit level or even book, but remember it has to be completely horizontal. Measure the distance from the top of the spirit level (or the book) to the ground (not the ankle). If having problems ask somebody for help.
