Ring Size Guide

Find your fit at home in a couple of minutes: measure your finger, or a ring that already fits, then read your size off the chart.

Last updated 24 September 2026

How to measure

Measure your finger

  1. Wrap a thin strip of paper or a non-stretch string snugly around the base of the finger you are buying for.
  2. Mark the point where the end overlaps.
  3. Lay it flat and measure from the end to the mark in millimetres. That length is your finger’s circumference.
  4. Find the nearest value in the Inside circumference column of the chart below.

Or measure a ring that fits

  1. Pick a ring that fits the same finger comfortably.
  2. Measure the inside diameter in millimetres, edge to edge across the widest point, without including the metal.
  3. Find the nearest value in the Inside diameter column of the chart below.

Tips for an accurate fit

  • Measure at the end of the day, when fingers are at their largest.
  • Measure when your hands are warm. Cold fingers are smaller and will give a size that feels tight later.
  • The ring has to pass over your knuckle. If your knuckle is wider than the base of your finger, measure both and choose a size in between.
  • Measure two or three times. If you land between two sizes, choose the larger one.
  • Wide bands sit tighter than slim ones, so consider half a size up for a broad band.
