Ring Size Guide
Australia and New Zealand use letter sizes. Our rings are made in sizes F to Z, with other sizes available on request.
Use the measurements below to find your size. Diameter is the distance across the inside of a ring; circumference is the distance around the inside.

How to measure
- Wrap a strip of paper around the base of the finger, snug but able to slide over the knuckle.
- Mark where it overlaps and measure the length in millimetres — that's the circumference.
- Match it to the table. If you're between sizes, choose the larger one.
Measure at the end of the day, when fingers are slightly larger.
