Size Guide

Two minutes with a strip of paper or a soft tape, and you order the right size the first time.

Chains & necklaces

Chain length is measured end to end, clasp included. The same length sits a little higher on a broad neck or chest.

Measure at home in 2 minutes

You need a strip of paper (or a string or shoelace), a pen and a ruler.

  1. Take a string or a shoelace and mark on it the length you are considering, for example 56 cm.
  2. Hold the two marks together at the back of your neck, wearing the kind of top you usually wear.
  3. Look in a mirror: the lowest point of the string is where the chain will sit.
  4. Too high or too low? Try 5 cm more or less: that is one size up or down.

Already own a chain you like? Lay it flat, clasp closed, and measure it end to end. A broad neck or chest makes every length sit a little higher.

No ruler? A bank card is 8.6 cm long: count how many fit along your strip.

Bracelets

Measure your wrist, then add a little room depending on how you like it to sit.

Measure at home in 2 minutes

You need a strip of paper (or a string or shoelace), a pen and a ruler.

  1. Wrap the strip around your wrist, just above the wrist bone, snug but not tight.
  2. Mark with the pen where the end overlaps.
  3. Lay it flat and measure from the end to the mark: that is your wrist size.
  4. Find your wrist in the table below and read the bracelet length, close fit or looser.

Already have a bracelet that fits well? Lay it flat, clasp closed, measure it end to end and order that length.

Between two lengths? Take the longer one for a chain bracelet, the shorter one for a cuff or a beaded style. Adjustable styles fit most wrists.

Rings

Two ways to find your size. Measure at the end of the day, when fingers are slightly larger.

Measure at home in 2 minutes

You need a strip of paper (or a string or shoelace), a pen and a ruler.

With a ring that fits (most accurate)

  1. Lay a ring you wear on that finger on the ruler and measure the inside diameter, edge to edge, in millimetres.
  2. Find that diameter in the table below.

With a strip of paper

  1. Wrap the strip around the base of your finger: it must still slide over the knuckle.
  2. Mark where it overlaps, lay it flat and measure it in millimetres: that is the circumference. Find it in the table below.

Measure at the end of the day, when fingers are slightly larger.

Half sizes sit halfway between two rows, about 0.4 mm of diameter.

Good to know: wide bands (8 mm and more) feel tighter, so if you are between two sizes, take the larger one. Tungsten carbide cannot be resized: measure twice.
