Ring Sizing Guide

Getting the size right matters, so here's how to find yours. If you already have a ring that fits the finger you're buying for, measure its inside diameter and match it to the chart below. If you know your size in another country's system, the chart converts it.

I work in Australian ring sizes. If you're outside Australia, go by the inside diameter.

Not sure of your size?

  • Visit a local jeweller and ask them to measure you in Australian or UK sizes.

Good to know

  • Every piece is made in your size, so choose it carefully when you order.
  • Your first resize is free if the fit isn't quite right.
  • For wide bands or chunkier styles, go up half a size from your measured size for a comfortable fit.
