Do you round your height up or down?

You might get better results by telling the unadulterated truth. In my experience, people (in your presumed case, women) are shocked, thrilled and surprised by getting the truth. There are SO MANY lying buttewhips out there. Distinguish yourself by telling the truth. You BOTH will feel better. I know that’s true.

5’11” is TALL.

Richard Kiel used to do this, He says he was 7ft 2 but in fact he was only 7ft 1 ½ inches. He must have felt inadequate.

I don't round at all.

I might if I were 5' .5 or 1", or 4'11", but I'm 5'6", so rounding either way would be silly.

I don't round

Neither, I don't round anything. I'm now 4' 11" on the dot but I used to be 5 ft 1 and 1/2 inch and I never rounded it up to 5' 2" even though you'd think I would love to do so, lol. Short is short.

Nah, I'm 4'12". 😉

I'm 5'7" and I round up to 6'5".
