How to Find Your Ring Size
Getting a comfortable, accurate fit starts with knowing your ring size. Use either of the methods below, then double-check with the conversion chart. If you're ever unsure, our team is happy to help confirm your size before you order.
Method 1: Measure Your Finger
- Cut a thin strip of paper or a piece of non-stretchy string about 15cm (6in) long.
- Wrap it snugly around the base of the finger you'll wear the ring on, ideally at the end of the day when your finger is at its largest.
- Mark the point where the strip overlaps to complete a full circle.
- Lay the strip flat and measure the length in millimetres with a ruler.
- Match that measurement to the closest size in the chart below.
Method 2: Measure An Existing Ring
- Choose a ring that already fits the intended finger comfortably.
- Lay it on a ruler (or a printable ring sizer) and measure the inside diameter, edge to edge, in millimetres.
- Match the measurement to the closest size in the chart below.

These measurements are provided as a general guide. Finger size can vary slightly with temperature and time of day, so if you are between sizes we generally recommend sizing up. For a guaranteed precise fit, visit a local jeweller for professional sizing or get in touch with our team.
A Few Tips
- Measure at the end of the day, when fingers tend to be at their largest.
- Avoid measuring when your hands are cold, since fingers can shrink slightly.
- Wider band styles fit more snugly, so consider sizing up half a size for wide bands.
- Buying as a surprise? Borrowing a ring your recipient already wears and measuring it is usually the most reliable option.
