Find your ring size
MEASURING YOUR FINGERS AT HOME
First, decide which finger you'd like to wear your ring on. Remember, fingers on your dominant hand are usually slightly larger than those on your non-dominant hand, so take that into account when measuring.
Make sure your finger is at its natural size before measuring. Cold weather can make your fingers shrink, while heat may cause them to swell.
HOW TO DETERMINE YOUR RING SIZE
Cut a strip of paper or use a piece of string.
Wrap it snugly around the base of your finger, making sure it's as tight as possible, and mark where the ends meet.
Measure the marked length with a ruler and use the size chart below to find your ring size.
Double-check to ensure accuracy.
