Ring Size Guide

Find your size on screen with a bank card and a ring you own, or use the chart. If you are between sizes, we generally recommend choosing the larger size for a more comfortable fit.

Find your ring size

1 · Calibrate your screen

Hold a bank card flat against the screen, over the outline. Drag the slider until the outline matches the card's width exactly.

Bank card
No card? Use your finger circumference

Wrap a strip of paper around the base of your finger, mark where it overlaps, and measure the length in millimetres.

How to measure your finger at home

No ring to hand? Measure your finger circumference instead:

  1. Wrap: wrap a strip of paper or a piece of string snugly around the base of the finger you will wear the ring on.
  2. Mark: mark the point where the paper or string overlaps.
  3. Measure: lay it flat against a ruler and read the length in millimetres. This is your finger circumference.
  4. Match: find the closest circumference in the chart to identify your size.

Fingers change slightly with the time of day and temperature. For the most accurate result, measure at the end of the day, when your hands are warm.

Measuring a ring you own

If you own a ring that fits well, measure its inside diameter across the centre, excluding the metal, and compare it to the Inside diameter column in the chart.
