This problem in online dating doesn't just apply to the single physical characteristic of height. It's a clusterfuck of ticking boxes and underdeveloped expectations. A 5 year old boy might tick "no girls", while a 14 year old boy might tick "big boobs", and a 30 year old man might tick "good education and stable job."

It's as if we all go into it like ordering at a Burger King, except Have it your way (tm) comes out tasting like crap because we realize we aren't chefs. Online dating is how a bureaucrat decides to choose their life partner. The boxes you tick in online dating aren't important and are there just to pander to users.
