Not sure of your ring size? Here's how to find it, and how our sizes compare across systems.

Measure at home

Wrap a strip of paper or string around the base of your finger, mark where it overlaps, then measure the length in millimetres. That's your finger's circumference — use the table below to find your size. Measure at the end of the day, when fingers are largest, and avoid measuring when cold.

Between sizes?

If you're between two sizes, we generally recommend sizing up — a ring that's slightly loose is easier to resize than one that's too tight. Get in touch if you'd like us to post you a free ring sizer.
