Proper sizing should be determined in number of inches, not a letter of the alphabet. However, we Americans prefer generalization and simplifications so most sizes are identified as XS, SM, MED, LG and XL.

The method described, below is 90%+ accurate.

Using a tape measure (in inches), press the starting end of the tape between the thumb knuckle and hand (fist) knuckles. Wrap the tape around the hand knuckles until you reach the beginning or where you started this unique adventure. The thumb is not included in the wrap around (sorry, thumb).

Read the number of inches where your tape end meets your "wrap around" and you have the approximate numeric size of your hand. Here are some matchups of the numerics with some of our styles and sizes:
