I've actually found taller women, over 6', seem more likely to date shorter men. It's probably because most men are shorter to them, so they just get used to it instead of holding out for that perfect man taller woman shorter image in their minds.
As a tall man myself, everyone shorter than me is the same height in my mind. If a girl is 5'0" or 5'11", those both feel like the same thing to me.
