There are 2 ways of measuring your ring size.

Option 1: Circumference

  1. Wrap a piece of string or paper strip around the base of your finger.

  2. Mark the string or paper where it overlaps to form a complete circle.

  3. Measure the length of the section of string or paper where it overlaps around the finger.

  4. Compare your measurement with this chart to determine your ring size.

  5. Please note: You need to take the knuckle into consideration when sizing. The base of your finger may be smaller then your knuckle. Also wider bands should be sized 1/2 - 1 size larger.

Option 2: Diameter

  1. Measure the diameter (distance across) of the ring you currently wear in MM.

  2. Compare your measurement with this chart to determine your ring size.

  3. When in doubt between two sizes, it is always safer to go to the next larger ring size. This ensures your new ring will fit you.
