Ordering the correct size
Your ring should fit comfortably, snug enough that it doesn’t fall off, but loose enough to slide over your knuckle. Finger size can change depending on the time of day and the weather. For best results, check your size at the end of the day when your fingers are warm. If you are buying for someone else, try to borrow a ring (from the correct finger).
This chart can be used to convert EU and US sizes into UK/Ireland sizes. It can also be used to find your ring size by measuring the diameter of a ring you already own.
