Jewelry size guide

2. Then measure the length of the wire in mm. The length of the thread corresponds to the inner circumference of the ring. See the table below to convert circumference to diameter (ring size).

1. Choose a ring you already have that fits well.

2. Measure the inner diameter with a ruler, where the ring is largest.

3. Match the measurement with the correct size, (20mm diameter is size 20). If you oscillate between two sizes, we recommend choosing the larger one.
