Three simple ways to find your perfect fit — at home or with our team.
Take a ring that already fits and measure its inner diameter in millimetres. Match it to the chart below.
Wrap a strip of paper around your finger, mark where it overlaps, and measure the length (circumference) in mm.
| Diameter (mm) | Circumference (mm) | UK / AU | US | EU |
|---|---|---|---|---|
| 15.7 | 49.3 | J | 5 | 49 |
| 16.5 | 51.9 | L | 6 | 52 |
| 17.3 | 54.4 | N | 7 | 54 |
| 18.1 | 57.0 | P | 8 | 57 |
| 18.9 | 59.5 | R | 9 | 59 |
| 19.8 | 62.1 | T | 10 | 62 |
| 20.6 | 64.6 | V | 11 | 65 |
Tip: measure at the end of the day when fingers are largest, and avoid measuring when cold.
