For our rings, we use ring sizes that are common in Germany, Austria, and Switzerland. If only an international size is known, you can quickly determine the correct ring size using our ring size chart: simply look up the American, British, French, or Japanese size and read off the corresponding German ring size. And if the ring size is not known at all, our ring template will help you find the correct size based on the ring size chart.
