What Are Ring Sizes?

Ring sizes are the various different widths (or diameters) rings can be made in. Just like shoe sizes, the sizes of rings vary slightly depending on the country's measurement system you're using.

Australian Ring Size Guide

Australian ring sizing follows a scale of letters, typically from ring size F through to Z. Standard women's ring sizes usually fall into three categories:  Small (I-M), Medium (N-Q), Large (R-U) .

Men's rings are usually at the larger end of the scale, although this is not always the case. Each Australian ring size letter corresponds to a particular diameter in millimetres, which matches your finger width.
