Looking to find your ring size?
View our international ring size chart below to work out your finger size.
If you are between sizes, order a larger size. Make sure your finger is at normal body temperature (fingers shrink or expand when cold or hot). If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around.
