Awesome topic!
Right now, many men incorrectly believe that women want a taller man for evolutionary reasons-to protect us and our offspring. But if you ask women, it's about feeling feminine.
This is something that I've been saying for years. Recent research has shown that, in the past, short men did no worse than tall men in mating. I personally believe that this is a societal creation, as opposed to an evolutionary one.
Anyway, I'm 5'6 and prefer girls shorter than me (generally 5'2 and below), but I have dated girls my height and taller. But I've never dated a girl taller than 5'9/5'10 (although I have hooked up with girls over 6 feet). To be honest, I admit that I'm intimidated by girls taller than me so I don't really go for them all that much, but I've found that I have the same amount of success with them as shorter girls.
The only place where it seems to make a difference is online. BUT I tried the same experiment as the people in the article (I tried increasing my height to 5'10, then to 6'0). I didn't really do all that much better. I had a few ugly girls message me here and there, but I didn't notice any drastic increase in the number of responses I got.
Of course, when using online dating sites, you're generally dealing with the bottom of the barrel in quality (and that's saying A LOT, in terms of American women).
