Most softball gloves are referenced for size by inches. They are measured by starting at the top of the index finger of the glove and measuring down the finger, along the inside pocket and then out to the heel of the glove. Typically, they have a range of 11 to 14.75 inches. The sizes of softball catchers mitts, while also expressed in inches, are measured by circumference.

Usually, a softball catchers’ mitt measures 30 inches for youth size up to 34.5 inches for adults with a half inch incremental sizes in this range. Note that youth ball gloves typically have smaller wrist openings and finger stalls than those designed for adults. Softball catcher’s mitts also usually have a thick pad around the circumference of the mitt with thick padding in the finger area and less padding in the palm area.
