Two ways to determine your ring size

Do you already have a ring that fits well? You can measure that. If not, measure your finger instead.

Method 1: Measure your finger

Cut a piece of paper or string to about 10 cm (approx. 4 inches).

Wrap it around the finger where you want to wear the ring. Make sure it fits comfortably (not too tight, not too loose).

Mark the point where the paper or string overlaps.

- Lay it flat against a ruler and measure the length in millimeters (mm).

- This is the circumference in millimeter (mm) of your finger. Check our ring size chart above to convert this measurement to your correct size.


Method 2: Measure a ring

- Choose a ring that fits comfortably on the desired finger. (Our rings are mostly worn on the index finger, making it easy to spin with your thumb!)

- Place the ring on a ruler and measure the inside (diameter) of the ring in millimeters (mm) or inches.

- Check our ring size chart above here to convert this measurement to the correct ring size.

- This is the diameter ⌀ in millimeters (mm) of your ring.
