I'm 5'9" Reach of 74" but my friend is 5'7" and a reach of 78" he has monkey arms though
i'm 5'5 and my reach is 71' so i guess it isn't too bad
I'm 6'(about average) and my reach is 72''so I think somewhere around 72'' is the average.
it wont effect it. but if you have short arms, you probably shorts legs, and probably a short weiner. hahait's probably goind to surround really stupid but if you have short arms at your height does that effect your leg length?
