The right ring size is essential for a perfect fit and lasting comfort. Take a moment to determine your size – and don't worry: if it doesn't fit perfectly, we offer free resizing.
Measure an Existing Ring
Take a ring that already fits well on the intended finger. Measure the inner diameter in millimetres with a ruler, or place the ring on our conversion chart below until the inner circle matches exactly.
String or Paper Strip Method
Wrap a narrow strip of paper or string snugly around the base of your finger. Mark where it overlaps, measure the length in millimetres – that's your circumference, which you can look up in the table below.
Get Measured at a Jeweller
The most accurate option: have your size measured at a jewellery store using a professional ring sizer – free of charge and takes only a few minutes.
Good to Know
- Measure in the evening – fingers are usually slightly larger than in the morning.
- Avoid measuring with very cold hands, as fingers tend to shrink slightly.
- Wide bands (e.g. cathedral settings) fit more snugly – consider sizing up by half a size.
- If in doubt, choose slightly larger – we resize for free.
