Ring Size Guide
Not sure of your size? Measure at home in two minutes, ideally at the end of the day when your fingers are at their largest.
Measure your finger
- Wrap a thin strip of paper or string around the base of your finger.
- Mark where the ends overlap.
- Lay it flat and measure the length in mm. This is your circumference.
Measure a ring you own
- Pick a ring that fits the finger you want to wear the new one on.
- Place it on a ruler and measure the width inside the ring in mm. This is the inner diameter.
- Match your number in the chart below.
| Indian size | Inner diameter (mm) | Circumference (mm) |
|---|---|---|
| 8 | 15.3 | 48.0 |
| 10 | 15.9 | 50.0 |
| 12 Popular | 16.5 | 51.8 |
| 14 Popular | 17.3 | 54.4 |
| 16 | 18.1 | 57.0 |
| 18 | 18.9 | 59.5 |
| 20 | 19.8 | 62.1 |
Between two sizes? Choose the bigger one.
Wide band or a thick ring? Go up half a size.
Cold hands? Fingers shrink in the cold, so measure when they are warm.
