Ring sizing guide
Finding the perfect fit is easy. The most common sizes for women are L, M, and N. One of these is likely to be your ideal size. If you're not sure, don't worry—we've created this simple guide to ensure you get the right size the first time:
1. Measure a ring you own
If you have a ring that fits comfortably, measure its inside diameter with a ruler or tape measure. Once you have the measurement in millimetres, compare it to the chart below.
2. Measure your finger
- Take a thin piece of string or paper and wrap it around the base of your finger.
- Mark where it overlaps, then measure the length in millimetres.
- Find the corresponding size in the chart below based on your measurement
