How to measure your ring size

Cut a thin strip of paper or use a piece of string.
Wrap it snugly around the base of your finger — not too tight, not too loose.
Mark where the paper meets, then measure the length in mm.
Match the measurement to the CN Inner Diameter column above.

💡 Tips: Fingers tend to be slightly larger in the afternoon or evening due to body temperature. For the most accurate fit, measure at the end of the day. If you're between sizes, we recommend going up half a size.
