Take a thin strip of paper and wrap it comfortably around the base of your finger. Mark where the paper overlaps, then measure the marked length in millimetres. Compare your measurement with the finger circumference in our size chart to find your best fit.
Australia, New Zealand, and the UK use the same letter-based sizing system.
AU/NZ/UK O = US 7 = 54.4 mm circumference, Q = US 8 = 57.0 mm, S = US 9 = 59.5 mm, and U = US 10 = 62.1 mm.
Choose your AU/NZ/UK letter size first. Refer to the US number only when comparing with an international ring size. We recommend choosing the larger size for a more comfortable fit, especially if your fingers swell during the day.
