How to Measure Your Ring Size

Wrap

Wrap a thin strip of paper, string, or ribbon around the base of your finger. Make sure it feels snug but still comfortable.

Mark

Mark the point where the strip overlaps. Lay it flat and measure the length in millimetres with a ruler.

Match

Compare your measurement to the chart below. If you are between sizes, we recommend choosing the larger size.

For the most accurate fit, measure your finger at the end of the day when fingers are naturally a little larger. Avoid measuring when your hands are very cold, and measure more than once for the best result.

Helpful Sizing Tips

If You Are Between Sizes

We recommend choosing the larger size, especially for wider bands or if your fingers tend to swell during the day.

Measure More Than Once

For the best accuracy, measure your finger two or three times and use the average result.

Check an Existing Ring

If you already own a ring that fits well, measure the inside diameter and match it to the chart above.

Gifting a Ring

If you are buying as a gift and are unsure, choosing a slightly larger size is usually the safer option.
