When I last used online dating (4+ years ago), I saw a decent number of height requirements stated explicitly from female profiles. I always found this interesting, not because of the idea itself, but because they chose specific heights as cutoffs. It was particularly common to see women pick 6' as their cutoff. Many of these women were significantly shorter than 6', even if they wore heels. If you're 5'4" (say), can you really tell the difference between 5'10" and 6'? Are those two inches actually a dealbreaker? Walking past men on the street, can you actually filter out all men under 6' accurately and precisely? It seems extremely unlikely that anyone could do that unless they were quite close to 6' themselves. And yet it's trivial to filter out every guy under 6' on a site like OkCupid. The site provides built-in functionality to do so. I'm willing to bet a significant percentage of women stating they require a height of 6' or higher would often be willing in real life to date men much shorter than that, because they probably don't even know what 6' precisely looks like. It's also been convincingly demonstrated that men on dating sites inflate their height by 2 full inches on average. Suppose you don't really know what 6' precisely looks like and go on a date with a 5'10" guy claiming to be 6'. You may not realize he's not actually 6' and believe the claim from his profile. From here on out, your idea of dating "6'" men becomes reinforced based on faulty data.
