I'm curious...what do you consider short? You say you won't have kids with a girl under 6'0 but many people would consider a 5'11 girl to be tall.
I'm 5'7 and I've always been told by people that I'm tall.
I think the average height for women is 5'4 so I've always considered girls under that height to be short.
I guess everyone has different perceptions.
Edited to add:
The majority of my guy friends are over 6 feet tall (I like to be able to wear heels and not tower over my male friends). My closest, of course being my boyfriend (6'2) and his roommate (6'4). They've always said that girls over 6'0 are too tall and that it just looks unattractive. This is the consensus I've gotten from many of the guys I know. They want a girl who's tall but not too tall (between 5'6 and 5'9).
