All our rings are sized in US ring sizes. Here are two easy ways to find yours at home.
Option 1: Measure a ring you already own
Choose a ring that fits the finger you're buying for. Measure the inside diameter (edge to edge, across the middle) in millimetres and match it to the chart below.
Option 2: Measure your finger
- Wrap a thin strip of paper or string around the base of your finger.
- Mark where it overlaps, then lay it flat and measure the length in millimetres.
- Match that number to the circumference column below.

Some rings are offered in quarter sizes (for example 7.25) and show the inside circumference next to the size, like 7 (54mm). If you see a measurement in brackets, simply match it to your finger measurement.
Tips for the right fit
- Measure at the end of the day, when fingers are slightly larger, and not when your hands are cold.
- If you're between sizes, choose the larger size.
- Wide bands (over 6mm) fit more snugly, so consider going up half a size.
- Adjustable rings are noted on the product page.
