You can find out your ring size by measuring the circumference of your finger at the knuckle.
To get that number take a small strip of paper, wrap it around your knuckle and make a mark where it overlaps.

If you are between two sizes, take into consideration the season (cold weather usually means skinnier fingers), your knuckle-to-finger ratio and preferred fit, as well as how often you plan on taking it on and off, etc. If still in doubt we recommend you choose the smaller one, as this U shape leaves a bit of extra room and loose rings tend to get misshapen easier.
Many of our rings are U shaped (with a flat top), which makes them a bit more forgiving in the way they size. They are usually available in 3 sizes S: 4-5, M: 6-7, L: 8-9.
