Method 1: Measure a ring

The easiest way to find your ring size is by measuring the inside diameter of a ring that already fits you well.

If your measurement falls between two sizes, we recommend choosing the larger size.

Make sure to measure only the inside diameter of the ring. Do not include the ring’s edge, width or thickness in your measurement.

Method 2: Measure your finger

Cut a strip of paper approximately 1.5 to 2 cm wide and wrap it around the base of your finger. Use a pen to mark the point where the paper overlaps.

Then, use a ruler to measure the length up to the mark. This will give you the circumference of your finger, which you can use to find your ideal ring size.

For the most accurate result, we recommend measuring more than once, as finger size can vary depending on the time of day, temperature and weather
