Do you need to figure out your ring size? This handy little finger gauge will help you determine what size will fit you best. It measures U.S. sizes 1–17 in ½ -size increments.
Instructions: The finger sizer works like a belt. Simply push the end through the buckle to form a ring shape. Slip the sizer onto your finger. Adjust to give a comfortable fit, checking that it just slips back over the knuckle.
