Ring Size Guide

How To Measure Your Ring Size

Finding your perfect ring size at home is simple. Wrap a thin strip of paper or a piece of string around the base of the finger you'd like to wear the ring on. Mark where the paper or string overlaps, then measure the length in millimetres. Use the chart below to find your size.

Tip: Fingers can swell slightly in warm weather or at the end of the day, so measure when your hands are at a normal temperature for the most accurate result.
