Size Guide
Jewellery should feel like it belongs to you. Here is how to find your size before you order — it takes two minutes and a strip of paper.
Rings — measure at home
You need a strip of paper about 1 cm wide, a pen and a ruler.
- Wrap the strip around the base of the finger you want to wear the ring on. Snug, not tight — it has to slide over the knuckle.
- Mark where the paper overlaps.
- Unroll it and measure the length in millimetres.
That measurement is your European size. 54 mm of circumference means a European size 54.
Already own a ring that fits?
Even easier. Place it on a ruler and measure the inner diameter in millimetres, then read across:
| Inner diameter | Circumference | Europe | US | UK |
|---|---|---|---|---|
| 15.7 mm | 49 mm | 49 | 5 | J½ |
| 16.5 mm | 52 mm | 52 | 6 | L½ |
| 17.3 mm | 54 mm | 54 | 7 | N½ |
| 18.1 mm | 57 mm | 57 | 8 | P½ |
| 18.9 mm | 59.5 mm | 59.5 | 9 | R½ |
Three things that change everything
- Measure at the end of the day. Fingers are at their largest in the evening and in warm weather. A ring measured first thing in the morning will feel tight by dinner.
- Wide bands run smaller. If you are between two sizes and the band is thick, take the larger one.
- Check the knuckle, not just the base. If your knuckle is noticeably wider, size for the knuckle — a ring you cannot get past it is a ring you will never wear.
Necklaces — where each length sits
Necklace length is measured end to end, clasp included. As a general guide, on an average adult neck:
| Length | Where it falls |
|---|---|
| 35–38 cm | Choker — sits around the base of the neck |
| 40–42 cm | Just on the collarbone. The most versatile length. |
| 45 cm | Slightly below the collarbone — the classic pendant length |
| 50–55 cm | Upper chest. Ideal as the longest layer. |
Layering tip: leave at least 5 cm between two chains. Any closer and they tangle rather than layer.
Bracelets and anklets
Wrap the paper strip around your wrist — or just above the ankle bone — and add 1.5 to 2 cm for comfort. A bracelet should be able to rotate freely without sliding over your hand.
Earrings and piercings
Nothing to measure. Hoops and studs are one size; only the diameter of a hoop changes how bold it looks.
For a helix or a second hole, our flat-back posts sit flush against the back of the ear — nothing catches on a jumper and nothing presses into your ear at night.

Ordering a gift and have no idea of their size? Necklaces, bracelets and earrings are far safer bets than rings.
