How to Measure Your Ring Size

Wrap

Wrap a thin strip of paper, string, or ribbon around the base of your finger. It should feel snug, but not tight.

Mark

Mark the point where the strip overlaps, then lay it flat and measure the length in millimetres.

Match

Compare your measurement to the chart below. If you fall between sizes, choose the larger size for a more comfortable fit.

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

Helpful Sizing Tips

If You Are Between Sizes

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

Measure More Than Once

Measure your finger two or three times and use the closest consistent result.

Check an Existing Ring

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

Buying as a Gift

If you are unsure, choosing slightly larger is usually safer than choosing too small.
