Giving your height and reach is not enough information to even guess what weight class you belong in. please give a weight that you currently are at or at least one you can get to inside a week otherwise no one on earth could even make an accurate guess of the information you have given!
We need to know your weight
we need your weight, cuz some guys can be 5'10" and fight at heavyweight and other guys can be 6'3" and fight at lightweight. It depends on your weight
I am 16 years old and just started boxing. I'm 6"1 inches and have a 70 inch wing span. I know I have a rather small wing span in comparison to my height but what weight category would suit me in boxing?
