HandBand Pro® OFFICIAL size fit most hands. If your hand measures an average of 2 inches or more between the crook of your thumb and the base of your fingers, this size is for you.
The ELITE PETITE size is specially created for very small hands. If your hand measures a lot less than 2 inches in width (1 1/2 inches or so) between the crook of the thumb and the base of the fingers (callus line), our ELITE PETITE size may be a better fit for you.
It's important that the top edge of the grip covers your callus line but that it doesn't cover the first knuckle of the fingers.
