A ring that pinches stays in the drawer. One that is too loose spins or gets lost. The good news: You can determine your ring size yourself at home in just a few minutes.
Method 1: With thread or a strip of paper
- Wrap a thin piece of thread or a narrow strip of paper around the finger you want to wear the ring on.
- Mark the point where the ends meet. The strip should fit snugly but not constrict.
- Measure the length in millimeters with a ruler. This is your finger circumference.
For European ring sizes, the circumference in millimeters corresponds directly to the size: a 54 mm circumference equals ring size 54.
Method 2: With a ring that fits you
Place a well-fitting ring on a ruler and measure the inside diameter from inner edge to inner edge. Multiply the value by 3.14 – this will give you the circumference and thus your EU size. Example: 17.3 mm × 3.14 ≈ 54.
EU and US conversion (guidelines)
| EU (circumference in mm) | US |
|---|---|

| 54 | 7 |
| 57 | 8 |
| 59–60 | 9 |
| 62 | 10 |
Tips for an accurate result
- Measure in the evening: Fingers are slightly thicker in the evening and in warm weather than in the morning or in cold weather.
- Remember the joint: The ring must fit over the knuckle. If your measurement is close, choose the next larger size.
- Wide rings: For band rings and signet rings from about 6 mm wide, it is better to choose half to a full size larger.
- Measure twice: Repeat the measurement to rule out reading errors.
Finding out the ring size for a gift
You want to surprise them and don't know the size? Discreetly borrow a ring that the person wears on the same finger and measure it as described above. Even easier: Choose an adjustable ring that adapts to any size.
Many of our rings are adjustable, for example the promise ring with 0.5 ct moissanite, the pearl ring with 9 mm freshwater pearl or the pearl ring 11 mm with double halo. For men, there are adjustable signet rings.
