Find out your true size from the comfort of your home.
Wrap the sizer around the finger you wish to size. Put the end of the sizer through the “buckle,” until you have a very large ring you can easily move from finger to finger. Gently pull it tighter until you have the correct size. The correct size should allow the ring sizer to move over the knuckle without too much effort. If you are in between sizes, it is best to go with the larger size.
