Thomas Sabo Ring star with blue stones TR2550U
How to determine your ring size
Thomas Sabo, Ania Haie, Save Brave Engelsrufer specify the ring sizes by the inner circumference of the ring in millimetre (mm). For example size 44 corresponds to 44 mm.

You can easily determine your own ring size with a measuring tape or a cord. To measure simply place the cord (or the measuring tape) around the finger where you want to put the ring. The ends of the cord should be marked.

Below chart shows how these Eu sizes translates into other sizes:
