The 2 standard sizes for grips are .580 and .600 (also known as 58 and 60) which refer to the core diameter size. These sizes are considered standard because most shafts also have a diameter of .580 or .600 inches. However you can actually mix and match the standard grip and shaft sizes without any issues. The majority of golfers will not be able to tell if the grip and shaft are "mismatched".
