How To Measure
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.
5. Refer to the ring size chart to determine what ring size is.
