Well some people would say it doesn't matter, but others say they prefer shorter or taller. Very good question. I would have to say the only real way to answer this question is to go by the culture or preference of the said person. You would practically have to sample the entire population like by a census and see who they prefer for that culture. See how many people are of that general height. Then you will really see the true answer. My guess would be that the female could be anywhere under 5'5". The taller the male the taller the female could be in ratio. I am 6'3" and Amanda is 5'6". She is that same proportion smaller than me. So that's why the girl has to be so short.
