Sizing
Ring size guide
Measure at home in two minutes, then read your size off the chart. We offer US sizes 3 to 10, including half sizes.
How to measure
Two ways to measure
-
1. Measure a ring that fits
Pick a ring that fits the right finger. Measure straight across the inside, edge to edge, in millimeters. Find that inside diameter in the chart.
-
2. Or measure your finger
Wrap a strip of paper around the base of your finger. Mark where it overlaps, lay it flat and measure the length in millimeters. Find that circumference in the chart.
-
3. Check it twice
Measure at the end of the day, when your fingers are warm, and measure two or three times.

Tips for the right fit
- Between sizes? Choose the larger half size, especially for wider bands.
- Fingers swell in heat and shrink in the cold. Avoid measuring when your hands are very cold.
- The ring has to slide over your knuckle. If your knuckle is wide, size for the knuckle.
- Buying a surprise? Borrow a ring they wear on the same finger and measure its inside diameter.
- Any jeweler can size your finger in a minute. Ask for your US size.
