Sizing Guide
Not sure which size to pick? Use the chart below to match your ring size across US and UK sizing, or measure an existing ring to find your circumference and diameter.
How to measure
- Wrap a strip of paper or string around the base of your finger and mark where it overlaps, then measure the length in millimetres, that's your circumference.
- Or measure the inside diameter of a ring that already fits well.
- For the most accurate fit, measure at the end of the day when your fingers are at their largest.
