Ring size guide
Find your US ring size using inside diameter or finger circumference. Measure an existing ring that fits comfortably on the intended finger, or visit a local jeweler for professional sizing.
How to measure
- Using a ring: Measure the inside diameter of a ring that fits well and match it to the chart below.
- Using your finger: Wrap a strip of paper around the base of your finger, mark where it overlaps, measure the length in millimeters, and match to circumference.
- Wider bands: Consider sizing up by half a size for a comfortable fit.
- Between sizes: We recommend the larger size.
