Ring size guide
We make full US sizes. The bold letter is the exact UK match; the others fit best in that ring. The mm measurement is the true guide — between two sizes, round up.
| US | UK (best fit) | EU / circ. | Diameter |
|---|---|---|---|
| 3 | E, E½, F, F½ | 44.0 mm | 14.0 mm |
| 4 | G, G½, H, H½ | 47.0 mm | 15.0 mm |
| 5 | I, I½, J, J½ | 49.0 mm | 15.6 mm |
| 6 | K, K½, L, L½ | 51.75 mm | 16.5 mm |
| 7 | M, M½, N, N½ | 54.2 mm | 17.25 mm |
| 8 | O, O½, P, P½ | 57.0 mm | 18.1 mm |
| 9 | Q, Q½, R, R½ | 59.0 mm | 18.8 mm |
| 10 | S, S½, T, T½ | 62.0 mm | 19.7 mm |
Half or quarter US size? A .25 takes the size below (6.25 → 6); a .5 or .75 rounds up (6.5 or 6.75 → 7).
Measure at home
- Wrap paper or string around the base of your finger (not over the knuckle).
- Mark the overlap and measure the length in mm.
- Match it to the EU / circumference column. Or measure the inside of a ring you own and use the Diameter column.
Tip: measure at the end of the day, when fingers are largest. Between sizes? Size up.

Ring size conversion
Every brand sizes a little differently, so we measured our own rings. We make full US sizes, and the chart below maps each one to UK and EU sizes. The bold letter is the exact UK match; the others in that row are the in-between sizes that fit best in that ring.
| US | UK (best fit) | EU / circumference | Inner diameter |
|---|---|---|---|
| 3 | E, E½, F, F½ (or smaller) | 44.0 mm | 14.0 mm |
| 4 | G, G½, H, H½ | 47.0 mm | 15.0 mm |
| 5 | I, I½, J, J½ | 49.0 mm | 15.6 mm |
| 6 | K, K½, L, L½ | 51.75 mm | 16.5 mm |
| 7 | M, M½, N, N½ | 54.2 mm | 17.25 mm |
| 8 | O, O½, P, P½ | 57.0 mm | 18.1 mm |
| 9 | Q, Q½, R, R½ | 59.0 mm | 18.8 mm |
| 10 | S, S½, T, T½ (or larger) | 62.0 mm | 19.7 mm |
The millimetre measurement is the true guide — US, UK and EU are just labels that approximate it. Between two sizes? Round up.
Measure with string or paper
- Wrap a strip of paper or string snugly around the base of your finger — not over the knuckle.
- Mark where it overlaps.
- Lay it flat against a ruler and measure the length in mm.
- Match that number to the EU / circumference column above.
Measure a ring you own
- Take a ring that already fits the right finger well.
- Measure straight across the inside, in mm.
- Match it to the Inner diameter column above.
Necklace lengths
We currently offer our necklaces in 45 cm (18 in) and 50 cm (20 in). Here's where each length sits, so you can picture it before you choose.
| Length | Inches | Where it sits |
|---|---|---|
| 40 cm | 16 in | Choker — sits at the base of the neck |
| 45 cm | 18 in | Our most popular — rests on the collarbone |
| 50 cm | 20 in | Sits just below the collarbone — easy to layer |
| 55 cm | 22 in | Falls on the upper chest |
Bold lengths are the sizes we offer. 16 in and 22 in are shown for reference.
How to measure
- Take a piece of string and drape it around your neck where you'd like the necklace to sit.
- Mark the spot and measure the length against a ruler.
- Compare to the chart above. Layering two pieces? Choose lengths about 5 cm (2 in) apart so they sit nicely.
Bracelet sizes
The right bracelet fit leaves a little room to move comfortably. Measure your wrist first, then check the guide below.
How to measure your wrist
- Wrap a strip of paper or string around your wrist, just below the wrist bone (where a bracelet naturally sits).
- Mark where it overlaps and measure in cm — that's your wrist size.
- For a comfortable fit, add about 1.5–2 cm to your wrist measurement.
| Wrist measurement | Fit |
|---|---|
| 14–15 cm | Petite |
| 15–16.5 cm | Small / Average |
| 16.5–18 cm | Medium |
| 18–19.5 cm | Large |
