I'm 5'10", and I do have a mild preference for petite girls, but I've dated girls of all sizes, including one who was 6', so it really comes down to personality. I think most guys prefer girls shorter than they are, but I know a few who really like and prefer tall girls.
The average woman is 5'3" so I guess 60% of women are short?
Anyways, my height range is 3'4" to 7'6" of who I'd date. But as weird as it sounds, I have a slight preference for girls that are between 6'2" and 6'4" (give or take an inch), and yes, that would make them taller than me since I'm 6'0".
However, it's not much of a factor. I haven't dated any girls in my ideal height range yet so that shows how minimally important it is.
