How to Find Your Ring Size
Finding the perfect fit is easy. Use one of the methods below:
Method 1 — Measure an existing ring
Place an existing ring that fits well on a ruler and measure the inner diameter in millimetres. Use the table below to find your size.
Method 2 — Measure your finger
Wrap a strip of paper around the base of your finger. Mark where it overlaps, then measure the length with a ruler. Divide this measurement by 3.14 to get your diameter.
| UK Size | US Size | Diameter (mm) | Circumference (mm) |
|---|---|---|---|
| H | 4 | 14.9 | 46.8 |
| J | 5 | 15.7 | 49.3 |
| L | 6 | 16.5 | 51.9 |
| N | 7 | 17.3 | 54.4 |
| P | 8 | 18.2 | 57.2 |
| R | 9 | 19.0 | 59.7 |
| T | 10 | 19.8 | 62.2 |
💡 Tip: Measure your finger at the end of the day when fingers are slightly larger. If between sizes, choose the larger size. Most TEALWYN rings are available in standard UK sizes H to T.
