toddrdmd, your 1975 a2000 xl would be a 12.5" glove. measured from the top, middle of the web, through the palm to the middle of the heel. a flexible tape like a fabric tape measure helps. the current a2000 xl is the same size, the a2000 elo is slightly larger at 12.75", the a2000 dw5 slightly smaller at 12.0". visit the wilson baseball glove website for other dimensions. see
