The most commonly used method for finding your exact grip size is as follows: On your dominant hand, note that your palm has three main creases. Hold your hand flat, with the fingers alongside one another. Measure from the middle crease of your palm, up the line between your middle and ring fingers, to a point equal to the height of the tip of your ring finger. For most women, this measurement will fall between 4 1/8" and 4 3/8", for most men between 4 3/8" and 4 5/8". Juniors will usually measure less than 4".
