Find your ring size

How can you best determine your ring size? We’ll gladly explain.

Most ring sizes are expressed either in circumference in millimetres (European ring size) or in the inner diameter of the ring. Availability of sizes may differ per brand.

Measuring your ring size

1. Measure your finger by wrapping a ribbon or piece of string around it. Make sure it fits comfortably and does not pinch your finger. Mark where the ends meet and measure the length with a ruler or measuring tape. Find your size in the ring size table below. If your exact size is not available, choose the next larger size.

TIP: Your fingers swell when it is warm. Therefore, your size may vary depending on the season, time of day or temperature. Measure at different times of the day and use the average for the most accurate result.

2. If you already have a well-fitting ring for the same finger, measure its inner diameter with a ruler. The number of millimetres measured equals the diameter size.

Please note: Swarovski rings run small. We therefore recommend ordering one size up.
