Sizing
Ring size guide
Three simple ways to find your size at home, and a chart to convert it. For an exact fit, have your finger sized in the showroom.
How to measure
1. Measure a ring that fits
Lay a ring you already wear on a ruler and measure the inside edge to edge, in millimetres. Find that diameter in the chart below.
2. Wrap a strip of paper
Wrap a thin strip of paper or string around the base of your finger, mark where it overlaps, and measure the length. That is the circumference.
3. Try the virtual try-on
Pick a size in our virtual try-on to preview how a ring sits on your finger before you visit.
Tips for a good fit
- Measure at the end of the day, when fingers are at their largest, and not when your hands are cold.
- The ring has to pass over the knuckle. If your knuckle is wider, choose a size between the two measurements.
- Wide bands fit tighter than thin ones. For bands wider than about 6 mm, many people go up a half size.
- Your dominant hand is usually slightly larger.
- Between two sizes? Choose the larger one.
