Ring size guide
A smart ring is wider than most jewelry, so the right size matters. Here’s how to find yours in a couple of minutes.
Measure with a strip of paper
- Wrap a thin strip of paper snugly around the base of the finger you’ll wear the ring on.
- Mark where the paper overlaps, then measure the length in millimeters.
- Find the closest circumference below. Between two sizes? Choose the larger one.
Fingers are slightly larger at the end of the day and in warm weather, so that’s the best time to measure.
| US size | Circumference | Diameter |
|---|---|---|
| 7 | 54.4 mm | 17.3 mm |
| 8 | 57.0 mm | 18.1 mm |
| 9 | 59.5 mm | 18.9 mm |
| 10 | 62.1 mm | 19.8 mm |
| 11 | 64.6 mm | 20.6 mm |
| 12 | 67.2 mm | 21.4 mm |
| 13 | 69.7 mm | 22.2 mm |
