Ring Size Guide
Our sized rings come in three fixed sizes. They are 316L stainless steel and cannot be resized, not even by a jeweller — so it is worth measuring before you order.
| S | M | L | |
|---|---|---|---|
| Inner circumference | 59.5 mm | 62.1 mm | 64.6 mm |
| Inner diameter | 18.9 mm | 19.8 mm | 20.6 mm |
| EU / DE / AT / FR | 60 | 62 | 64 |
| US / CA | 9 | 10 | 11 |
| UK / AU | R½ | T½ | V½ |
| IT / ES / CH | 19.5 | 22.1 | 24.6 |
How to measure
- Cut a thin strip of paper, about 5 mm wide. Thick paper or card reads too large.
- Wrap it around the base of your finger. Snug — do not pull it tight. A firm pull reads 1 to 2 mm too small.
- Now slide it up over your knuckle. The ring has to pass your knuckle, so if it does not, loosen it until it does.
- Mark the overlap and measure the length in mm. Take the larger of the two: base or knuckle.
- Measure in the evening. Fingers are up to a full millimetre smaller in the morning and in the cold.
- Match your measurement to the inner circumference row above.
If you are between two sizes
On PETAR (8–10 mm) and CUBAN (6–8 mm) take the larger size — a wide band sits noticeably tighter than a thin one at the same circumference. On COMO (4–6 mm) take whichever number is closer.
Our range
These rings run from 59.5 mm to 64.6 mm inner circumference. If you measure more than 65 mm, we do not currently have a sized ring that will fit you.
