Ring size
guide
Every ring is made to order in your size, so it’s worth a minute to get it right. Here are three easy ways to find yours.
sizes F to T
Find your size
- 01
Use a ring you already wear
Measure straight across the inside of the ring, edge to edge, in millimetres. Find that number in the “inside diameter” column below. Use a ring worn on the same finger.
- 02
Measure your finger
Wrap a strip of paper or string snugly around the base of your finger, mark where it meets, then lay it flat and measure the length. That’s your circumference.
- 03
Ask a jeweller
Any jeweller can size your finger in a minute, usually for free. Ask for your Australian (letter) size.

Good to know
Measure at the end of the day when your hands are warm, as fingers are smaller in the morning and in the cold. Make sure the ring will slide over your knuckle. Wider bands, like the Star Limpet ring, sit a little tighter, so go up half a size if you’re unsure.
