We use the inner ring diameter as the ring size. We prepared a table to ensure you order the right size and can compare it to other ring sizing scales.

How to measure your size

1. Measure your own ring diameter

If you do it right, you can get a very accurate result by using this method. Measure the inner diameter of an existing ring that fits you. Your desired ring size is the inner diameter in mm.

2. Measure your finger circumference

You will need a thin paper strip or some string for this method. Wrap it around the finger you want to wear your ring. Mark crossing spots on both sides of the strip. Then straighten the strip, add it to the ruler and enter the length of the strip in mm to the field below to get your ring size and compare it to the table below.
