1. Measure your finger

All you need for this method is a pen, a stripe of paper and a ruler. Simply cut out a 10cm long, narrow strip of paper and wrap it lengthways around the finger you would like to wear the ring on. Then mark the end of the overlap with a pen and measure the marked distance with the ruler. The result in millimeters then corresponds to your ring size. For example, a distance of 5,4 cm corresponds to a ring size 54.

2. Measure an existing ring

Another easy way to make sure you get what you’re looking for is to find an existing ring and measure the inner diameter or inner circumference. Multiply the value by 3.14, the result corresponds to the ring size. You can also take a look at our handy international converter if you know your size in another region.
Handy tip: If your existing ring is in between two sizes, we suggest sizing up!
