Ring Size Guide
Measure a ring you already own
- Choose a ring that fits comfortably on the finger you will wear your new ring on.
- Measure the inside diameter of the ring in millimeters, from edge to edge.
- Find the closest diameter in the table below and choose that size. If you are between two sizes, we recommend the larger one.
| US size | Inside diameter |
|---|---|
| 5 | 15.7 mm |
| 6 | 16.5 mm |
| 7 | 17.3 mm |
| 8 | 18.1 mm |
| 9 | 18.9 mm |
| 10 | 19.8 mm |
| 11 | 20.6 mm |
| 12 | 21.4 mm |
| 13 | 22.2 mm |
| 14 | 23.0 mm |
| 15 | 23.8 mm |
| 16 | 24.6 mm |
Measure your finger
- Take a soft tape measure, a piece of string or a thin strip of paper.
- Wrap it around the base of the finger you will wear the ring on.
- Mark the point where it overlaps, making sure it is snug but can still slide over your knuckle.
- Lay it flat, measure the length and compare it with the finger circumference in the chart above.
Tip: measure at the end of the day when your fingers are warmest. For wide signet and statement rings, choose a half size up.
