I think the perfect height for a guy should be 5’9", not too tall not too short, and easy to date any girls.
Though any height is OK if you are 3"-4" taller than the girls.
I am Asian guy only 5’6", and most girls here are below 5’2". So there have not been an issue for the local girl in my country, but compare to the european/US girls I realised I am too short ![]()
