How do I determine which ring size is right for me?

Ring dimensions are given in mm and are measured based on the diameter of the inner circle. Like clothes, rings have standard measurements, ie size 16.5 corresponds to the same measurements in every e-shop and jewelry store.

Since you can already find a larger selection of jewelry in e-shops than in retail stores, there are also several ways to find out your ring size.
