Ring Size Chart
Looking to find your ring size?
If you would like to determine your ring size immediately, we suggest that you print our simple Ring Sizing Guide and read the instructions carefully to ensure accurate sizing.
Before you print, be sure to check that page scaling is set to “none” on your print dialogue box.
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.
