This simple belt-style ring sizer makes it easy to determine the right size each and every time.
Simply slip one end of the sizer through the other and slide onto your finger. Pull the tab end until the sizer is snug but not tight. Ensure you can then can slide the sizer back off of your finger paying special attention to the knuckle. You should feel friction over your knuckle but if you have to squeeze your knuckle through or use force to get it off loosen the sizer and try again. Use the arrow and corresponding numbers to read off your ring size!
