step1
Measure
the circumference of the fullest part of the palm, excluding the thumb.

step2 Round up to the next highest inch. Then add 1 to the measurement to determine your glove size: (ex. 8" + 1 = 9) Thus 9 would be the glove size. 
step3 Measure both hands to determine if one hand is bigger than the other. Take the bigger size and open up our size chart and find the corresponding glove size. This size is very generic, you must do one more step. 
step4 Look down the list of the gloves attributes to see the specific sizing of the product. If a glove runs a "half size small" then move up to the next size. Remember: Goalkeeping gloves should be worn big, as much as 1.5" over the length of your fingers.
