From Quora Thread entitled "What is tall for you?"

Hi there, you are plenty tall enough to find a great girl assuming you behave well and have a good personality, reasonable looks, decent intelligence and grades, are mature for your age, emotionally stable, and don't have bad breath or something equally smelly. 

Whether a given girl will like you at a height of 6 feet depends on where you live, and it also depends on the personality and attitudes of the tall girl who is slightly taller than you.  I wouldn't count on her dating a guy who is shorter than her, because human mating research shows that it's human nature and instinctive for a female to get the tallest man she can enjoy company with, as her mate. The reason for this female preference for the tallest man she can enjoy company with, is that taller men on average get more promotions and better wages than equally qualified men of shorter height.  But don't rule it out. I know of several situations where a tall girl dated a slightly less tall guy, and it worked out well and became a marriage.

Most girls like a guy to be at least 6 feet tall, here in Texas where I live.  Usually the taller the girl is, the taller she wants her boyfriend to be.  Among women and girls, it's considered socially funny to have a boyfriend who is shorter than you are.  Texan guys and gals on average are slightly taller than the national average.   In a place like Mexico, Hawaii, China or Japan where men are shorter on average, you would be very impressive and girls who didn't mind the cultural and language barrier would be flirting with you like crazy. 

My brother in law is approx. 6 feet tall and he lives in LA, where there are a lot of tall young men and tall young ladies looking for acting work or modeling work. My brother in law was having a hard time finding a girlfriend in LA who found him impressive, because in LA the ladies and the men are both are overall taller, and he seems average. Well eventually he met an ethnically Japanese lady, about 5'10" who is also a ping pong expert, at a ping pong club he plays at.  Since Japanese guys tend to be short, even Japanese-American guys in LA, this Japanese lady was impressed with his 6 feet height and also impressed that he can beat her at ping pong.  They are now a happy couple.

My husband is 6 feet tall, I could have gotten a taller man if I wanted to, but I am only 5'2" so I am a bit uncomfortable with a man who is over 6 feet tall. 

An ex roommate of mine from college who is male and only 5'9" married a lady who is 5'11" - So again, don't give up just yet.  If you like her a lot, I say give it a try. Can't hurt to see if it works out or not.

Oh, and there are also special shoes a guy can buy that will artificially make him 1-2 inches taller without it being obvious.  Short stars like Tom Cruise, Dustin Hoffman, Ben Stiller, and Humphrey Bogart have worn them.  Maybe those would be worth a try?  I mean, it's no different from girls wearing a padded bra, and most females do that, from time to time, especially for a formal occasion. Like I did at prom, and at my wedding.

Or, saying no to the special shoes is totally fine too, because you are plenty tall already. Up to you.
