Indian and US ring sizes side by side, bangle sizing, and how to measure accurately at home.
Our rings are listed in US sizes. If you know your Indian size, or you have measured your finger using the instructions below, read across to find the US size to order.
| Indian size | US size | Diameter (mm) | Circumference (mm) |
|---|---|---|---|
| 6 | 3 | 14.0 | 44.0 |
| 8 | 3¾ | 14.9 | 46.8 |
| 10 | 4¾ | 15.7 | 49.3 |
| 12 | 5¾ | 16.5 | 51.8 |
| 14 | 6¾ | 17.3 | 54.4 |
| 16 | 7½ | 18.1 | 56.9 |
| 18 | 8½ | 18.9 | 59.5 |
| 20 | 9¾ | 19.8 | 62.1 |
| 22 | 10¾ | 20.6 | 64.6 |
| 24 | 11¾ | 21.4 | 67.2 |
The two scales don't line up exactly — Indian sizes step about twice as far as US ones, so most Indian sizes fall between two US sizes. Where yours does, take the larger of the two. A ring that sits a little loose can be sized down neatly; one that won't pass the knuckle is unwearable until it's altered.
Not sure? Send us the diameter in millimetres and we'll tell you which size to order — that is more reliable than either scale.
| Size | Diameter (cm) | Circumference (cm) |
|---|---|---|
| 2.2 | 5.4 | 17.0 |
| 2.4 | 5.7 | 17.9 |
| 2.6 | 6.1 | 19.1 |
| 2.8 | 6.5 | 20.4 |
| 2.10 | 6.8 | 21.4 |
| 2.12 | 7.2 | 22.6 |
How to measure
Before you decide
Still unsure? Tell us the piece and we will talk it through before you order. Guessing costs you a return; asking costs a message.
Most plain bands can be resized by up to two sizes free within 90 days of purchase. Eternity bands, pavé-set designs and bangles cannot be resized — the stones run the whole way round, so there is nowhere to cut. On those, sizing matters more, which is why it is worth asking.
