The part (virtually) no bike company takes into account is BB drop. Most bikes, whether it's a 47cm or a 62cm, same BB drop-- but they'll put every crank length on there. Which means right off the bat, my pedal is 10mm closer to the ground than my wife's (hers 165mm, mine 175mm.) We tall(er) folks don't like pedal strike either. It's test-ridden her bike, looking much like a circus bear. I don't think I could do 165s. It's only a 10mm difference, but they felt really short.
