Find your ring size

Finding the right ring size is essential for a comfortable fit. 
Use one of the methods below, then refer to the ring size chart (below).

Measure an existing ring

Use a ring that already fits comfortably to find your size.

Measure its inner diameter in millimeters, from one inside edge to the opposite inside edge. Do not include the thickness of the band. 

Measure your finger

Measure the circumference of your intended finger using a piece of paper or string.

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

Mark where the paper or string meets, then measure its length.

Compare your measurement with a ring size chart to choose your size.

Tips for measuring

  • Measure at the end of the day, when your fingers are warm and at their largest.
  • Consider the width of the ring. Wider bands may require a slightly larger size for comfort.
  • If your fingers are prone to swelling or you are between sizes, consider a slightly larger size.
