Yup all the guys have the right idea. Try them on...some gloves will be your size but the fit might not be comfortable because of the leather or padding. You might also like the features of other brands. I suggest since your in T.O., run over to R. Nicholls...They have a wall of gloves on display and you can open them and try them on. Once you find your fit, then shop around for prices. Like farmboy says, "his Hatch gloves are on sale!".
Good luck!
