How to find your ring size

Option 1 — Measure a ring you already own (recommended)

The easiest way to find your size is to measure a ring you already own. Measure the inner diameter and compare it to our size chart above.

If you’re between sizes, we recommend sizing up for comfort.

Option 2 — Measure your finger

- Wrap a thin strip of paper or a string around the base of your finger

- Mark where it overlaps

- Measure the length in millimeters

- Use the chart above to find your size

Many of our rings are adjustable and designed to fit comfortably across multiple sizes. If you’re unsure, adjustable styles offer extra flexibility.
