Option A : Use sizer to measure finger
- Cut out the sizing guide to the right.
- Wrap the sizer around the knuckle (or the widest) of the finger to be sized. Start by placing the fat end of the strap on the finger and wrap it around until the fit is snug.
- Once wrapped , the number closest to the end is the ring size. Hash marks between the numbers represent half sizes. If in doubt move up to the next largest half size.
Option B : Use a current ring :
- If you have a ring that fits the finger to be sized, place it over the circles below, matching the inside edge of the ring to the drawing.
- If the ring falls between two sizes, choose the larger size.
