Measure Finger Size (mm)

1. Wrap a strip of paper or ribbon snugly around your finger, then use a pen to mark where the strip overlaps.
   
   
2. Measure the marked strip with a ruler - ensure it’s exact and don’t round up! The ribbon or paper strip should be comfortable enough to slip on and off your finger easily.

 

Measure Ring ⌀ (mm)

1. Using an existing ring that fits you well, place a ruler in front of the ring to measure the inside diameter.
   
   
2. Match it to the closest size in the chart below. If you are between sizes, we recommend choosing the larger size.
