Not sure if the data I just found is reliable, but according to that, only about 13% of males and 0.03% of females in the US are taller than 6 feet.
If you’re seeing a lot of women over six feet, you’re either around a lot of Dutch women or they’re wearing elevating shoes (heels, tall flats/clogs.) Or perhaps you slouch. :)
Also, many women wear heels making them seem taller.
How often do you see women not wearing any shoes? Unless you have a beach lifestyle it can't be that often?
I am 6’7” and I rarely see people my height, but when I do I have aa strange feeling because I am typically the tallest person in a room. When we are the same height, they feel taller to me because I am not familiar with looking up to the top of someone’s head.
