Size guide

How do I find my ring size?

To make sure you choose the right size, you can use 2 methods:

Measure an existing ring

  1. Select an existing ring that matches the desired finger.
  2. Measure the inner diameter of the ring (in mm).
  3. Use the table below to determine the size of your ring.

Measure the circumference of your finger

Wrap a strip of paper on your finger where you would like to wear the ring.

Make sure the paper fits tightly to your finger.

Mark where the two edges of the paper strip meet and measure the distance with a ruler (mm).

Use the table below to determine the size of your ring.
