Well, there's nothing wrong with my wingspan on paper - it's merely 2 CM less than my height. However, I've got shoulders of someone 5'10''-5'11'' and that's where I lose my arm length. I've compared my shoulder breadth with quite a few 5'8''+ guys, it's either equal to theirs or bigger. I'm 165-166 CMs with 18.5 Inch shoulders. I've also compared my arms with quite a few 5'3''-5'4'' people, almost all had arms longer than mine.
