I'm asking because the average height for a caucasian man is 5'10.5, but most caucasian men I know are 6'0+. That could just be where I live though. I know 5'9 is short, but my question is, am I out of range short, or just on the short end of average?
I have a significant number of white adult male friends who are under 5' 9" tall - and I have known several of them since they were children.
To the best of my knowledge and recollection, only two of them ever expressed even the slightest concern about their height while they were growing up. None of them seem to be fixated on their marginally below average stature in the manner that you seem to be.
There are much more important things to worry about in this world rather than a couple of inches lacking, here or there. Forget about the three inch shortfall below the six foot mark, and be grateful for the nine inches you acquired above the five.
Right don't worry about it dude because it is of no concern whatsoever. There is nothing wrong with your height.
I know very few men who are taller than 5'8" so I would say your on the low end of average
No pretty much average where I am.
