Ring Size Guide
To find your ring size, measure the inside diameter of a ring that already fits, or measure the circumference of your finger, then match the millimetres to the chart below. Our rings are handmade to order in the size you choose, so it is worth measuring carefully before you order.
How to measure your ring size at home
Method 1: measure a ring you already own
Take a ring that fits the intended finger and measure the inside diameter straight across the middle, in millimetres, with a ruler. Match that number to the Inside diameter column in the chart.
Method 2: measure your finger
Wrap a thin strip of paper or a piece of string snugly around the base of the finger. Mark where it overlaps, lay it flat, and measure the length in millimetres. That length is your finger circumference. Match it to the Inside circumference column.
Ring size chart
| US size | Inside diameter (mm) | Inside circumference (mm) |
|---|---|---|
| 5 | 15.7 | 49.3 |
| 6 | 16.5 | 51.9 |
| 7 | 17.3 | 54.4 |
| 8 | 18.2 | 57.0 |
| 9 | 19.0 | 59.5 |
| 10 | 19.8 | 62.1 |
| 11 | 20.6 | 64.6 |
| 12 | 21.4 | 67.2 |
| 13 | 22.2 | 69.7 |
| 14 | 23.0 | 72.3 |
| 15 | 23.8 | 74.8 |
European (EU) ring sizes correspond to the inside circumference in millimetres, so a ring measuring about 54 mm is roughly EU 54.
Tips for an accurate fit
- Measure at the end of the day, when your fingers are at their largest.
- Measure when your hands are warm, since cold fingers shrink slightly.
- Wide or chunky bands sit more snugly, so consider going up a size for a broad band.
- If you fall between two sizes, choose the larger one.
Ring size FAQ
How do I measure my ring size at home?
Measure the inside diameter of a ring that already fits, in millimetres, or wrap paper or string around your finger to get its circumference, then match the millimetres to our chart.
What if I am between two sizes?
Choose the larger size. A ring that sits slightly loose is more comfortable than one that is too tight, especially with a wider band.
Does band width change the fit?
Yes. Wide or chunky bands sit more snugly on the finger, so if your ring has a broad band, consider going up half a size to a full size.
How do US and EU ring sizes compare?
European ring sizes are based on the inside circumference in millimetres, so a US 7 of about 54 mm is roughly EU 54. Use the millimetre columns in the chart to convert between systems.
