We sell in AU/UK and US sizing. Not the same — and confusing if you're used to one system.
The quick version: AU/UK sizes use letters (J, L, N, P, Q, R, S, T, U, V…) while US sizes use numbers (5, 6, 7, 8, 9, 10, 11, 12…).
For a full conversion chart and circumference/diameter measurements for every size, head to our Size Guide page.
Most common sizes for reference:
-
Men's most common US size: 10
-
Women's most common US size: 6
Not sure which system you're working in? If someone told you your size at a jeweller in Australia, it's likely AU/UK (a letter). If you've bought a ring in the US or online from a US store, it's likely a US size (a number). Our size chart will cross reference both.
