Australian Ring Size System

The Australian ring size system uses letters (A-Z) similar to the UK system, as Australia follows British standards. Australian sizes are measured in millimeters based on the inside circumference of the ring. The Australian system is identical to the UK system and is used throughout Australia and New Zealand.

For the most accurate results, we recommend measuring your finger at the end of the day when your fingers are at their largest. If you're between sizes, it's usually better to choose the larger size.
