- Free Ring Sizer
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.
