Australian Ring Size Chart

Australian and New Zealand ring sizes — the same alphabetical system as the UK — with full US, EU, and mm conversions.

Australia and New Zealand use the same ring sizing system as the United Kingdom and Ireland — alphabetical letters from A through Z and beyond. If you know your UK ring size, it is identical to your Australian ring size. The same applies in South Africa and many other Commonwealth countries.

How to Measure for Australian Ring Sizes

The method is identical to measuring for UK sizes. Wrap a strip of paper around your finger, mark where it overlaps, and measure in mm. Find your circumference in the chart above to get your Australian letter size.

Shopping Between Australia and the US

Many Australians shop from US retailers and vice versa. The key conversions:

  • AUS J = US 5
  • AUS L = US 6
  • AUS N = US 7
  • AUS P = US 8
  • AUS R = US 9
  • AUS T = US 10
International shopping tip: When in doubt, always provide the inside diameter of your finger or an existing ring in mm. This measurement is universally understood by all jewellers worldwide, regardless of which sizing system they use.
