Ring sizes here are US sizes. If you are between two, take the larger one — a ring has to pass the knuckle.

1 · Measure with a strip of paper or string

1. Wrap it around the base of the finger, snug but not tight.
2. Mark where it overlaps and lay it flat against a ruler.
3. That length in millimetres is your circumference — find it in the table.

2 · Or measure a ring that already fits

1. Measure straight across the inside of the band, edge to edge.
2. That is the inside diameter — the middle column below.

Greyed sizes are not made in this ring.

3 · Or check it against your screen

A screen has to be told how big it is first, or the circles below mean nothing. Hold any bank card against the outline and drag until they match.

Place a ring you own over a circle. The circle should sit just inside the band.

Bracelets and chains are listed by their inner circumference — the size of the loop itself, not your wrist.

Measure your wrist

1. Wrap a strip of paper or string around your wrist, below the wrist bone.
2. Mark the overlap, lay it flat on a ruler and read the centimetres.
3. Add the allowance below for the fit you want.

A heavy link or a cuff wears shorter than a fine chain — if you are between two, the larger one is the safer pick.
