Ring Size Guide
We recommend that you double-check your size before placing your order to ensure that you receive the perfect fit.
Two ways to find your size
Measure your finger
- Take a measuring tape, or a strip of paper (no wider than 1 cm), a non-stretchy string or a cord, and a ruler.
- Wrap it snugly around the base of your finger and mark where it meets.
- Measure the length in mm. This is your EU size.
Measure a ring that fits
- Take a ring that fits the same finger of the same hand.
- Place it on a flat surface.
- Measure the inner diameter through the centre, from inner edge to inner edge, in mm.
- Find the closest value in the “Inner diameter” column of the chart below.
Mind your knuckle. Whichever method you use, measure your knuckle too. If it is noticeably wider than the base of your finger, choose the next size up or contact us.

The EU size equals the inner circumference of the ring in millimetres. US sizes and diameters are given for reference.
Choosing a wide ring
A wide band covers more of your finger and can feel tighter than a thin one of the same size. As a general guide:
| Band width | Recommended size |
|---|---|
| Up to 4 mm | Your measured size |
| 5–7 mm | 1 EU size larger |
| 8 mm and wider | 1–2 EU sizes larger |
The fit also depends on the design of the ring. If you are unsure, send us your measurement and the ring you are considering.
Good to know
Pick the right momentMeasure at the end of the day, when your fingers are not hot or cold.
Use the right handYour left and right hands differ slightly, so measure the finger you will wear the ring on.
Measure twiceRepeat the measurement on another day to be sure of the result.
