Someone who's shorter than 5'7/5'8 can't differentiate between 5'11, 6'0, or even 6'1.
I'm around 5'4 and having met guys at that height they all seemed tall asf to me, so considering most females are shorter than 5'7/5'8 i don't see how they could tell who's 5'11 and who's 6'1, unless they have measuring tapes with them chances are they wouldn't be able to tell at all. furthermore how many Men height fraud? quite a significant number right? those Chads and Chadlites who tell foids they're 6'1 or 6'3 are in actuality 5'11 and 6'1 respectively so in that sense it actually creates the illusion of actual 6'3 being much taller in which most cases it turns out to be.
As a type of anecdotal evidence:my cousin who's around 6'4 lives in New York and from what he told me the vast majority of girls think he is 6'7 or even taller when they first meet him, he even told me he likes to prank guys around them by asking their heights and when they tell him obvious frauded numbers they look like assclowns, one guy who said was he 6'0 barely even reached his shoulder.
