How To Measure Ring Size

If You Have An Existing Ring

1. Measure the diameter (mm) of a ring that fits the desired finger
2. Use the Ring Sizing Chart to locate your size

If Not, Measure Your Finger

1. Cut a piece of paper into a long thin strip
2. Wrap the piece of paper around your knuckle, which is the largest point the ring will have to be able to get over
3. Mark where the two ends of the paper first overlap with a marker
4. Measure the length with an mm ruler
5. Use the Ring Sizing Chart to determine what ring size is.
