What’s my ring size?
Here are 3 quick and easy methods to determine your ring size at home. Be sure to measure a few times because your size can be smaller if you are too cold and bigger if you are too warm.
Use string or floss to measure your ring size.
Wrap string or floss snugly around the base of your finger, marking where it first overlaps with a marker or pen.
Lay string beside a ruler and write down its length in millimetres.
Match the measurement to the 'String Method' chart below to find your ring size.
NOTE: If you have a larger knuckle, choose a half size bigger than the base of your finger.
Measure a ring you already own.
Grab a ruler and measure the interior diameter of your ring in millimetres.
