Interesting, owned plenty of racquets and never saw handle size presented this way before. For those not familiar with the normal sizing of the handle, an average grip is roughly 4 3/8" (size 3) or 4 1/2" (Size 4) for men, 4 1/4 (Size 2) to 4 3/8" (Size 3) for women. A larger man's hand would take 4 5/8" (Size 5) while a smaller women's hand or older child would be 4 1/8 (Size 1) or less. Too large a grip can give slightly more control but puts more stress on the wrist and elbow leading to injury. Additional wrapping can add up to an 1/8".
