How to Measure

Option 1 — Measure a ring you already own:
Take a ring that fits the intended finger well. Measure the inside diameter in millimeters and match it to the closest number in the "Diameter" column above.

Option 2 — Paper strip method:
Wrap a thin strip of paper around the base of the finger. Mark where it overlaps, then measure that length in millimeters. Match it to the closest "Circumference" number above.

Tips:

Measure at the end of the day, when fingers tend to be slightly larger
Avoid measuring when hands are cold — fingers shrink in the cold
If you're between two sizes, we recommend sizing up, especially for wider bands like our koa wood styles

⚠️ Note: Due to the wood inlay, koa wood rings cannot be resized after purchase — please measure carefully before ordering.
