Our ring sizes are based on the inner circumference of the ring in millimeters, following the European ring size standard. To find your size, you can use one of the following methods:

  • Measure the circumference of your finger in millimeters, which directly corresponds to our size system.
  • Measure the diameter (Ø) of a ring you already own and refer to the chart below to convert it to our size system.
  • If you know your size in other ring size standards, use the chart below to convert it to our size system.
