Ring Size Guide
How to Measure
Option 1 — Measure a ring you already own Find a ring that fits the finger you're buying for. Lay it flat and measure the internal diameter in millimetres, from one inner edge straight across to the other. Match that number to the conversion chart below.
Option 2 — Measure your finger Wrap a strip of string or a thin piece of paper around the base of your finger, where the ring will sit. Mark where it overlaps, then measure that length in millimetres with a ruler. This gives you your finger's circumference — match it to the chart below.
A couple of things to keep in mind: measure at the end of the day, when fingers tend to be at their largest, and avoid measuring when your hands are cold, as fingers shrink slightly in lower temperatures. If you're between two sizes, we'd always recommend sizing up rather than down.
