A ring only really feels comfortable when the size is right. So choose your ring not just for how it looks, but also determine your ring size carefully — it makes wearing it far more enjoyable. Below we help you on your way.

European or American size?

Ring sizes differ per part of the world, and sometimes even within one country. In Europe you will mostly come across two systems: the European ring size and the American (USA) size. The table below shows how they relate.

How to find your ring size

You can determine your ring size in a few ways: with a ring stick or ring gauge, using the table above, or by measuring the circumference of your finger. Always measure at room temperature — with heat or cold your fingers become a little thicker or thinner. Also keep in mind that a wide ring fits more snugly: take it half a millimetre larger. For a very narrow ring, the opposite applies.

The easiest method

The simplest way is to measure a ring that already fits you well. Measure the inner diameter in the middle in millimetres — that number is your size. In the example below it is 18 mm (the drawing is not to scale).
