How to Measure Ring Size

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 a ruler (Print A4 Ruler).

5. Refer to ring size chart to determine what ring size is.
