What ring size to choose?

The most important factor when buying a ring is making sure you choose the right size. Here are 2 easy ways to measure your finger :

Method 1: Measure the diameter of one of your rings with a ruler

Measure the inside diameter of your ring with your ruler and note the size in mm. Compare your measurement with the chart above in the "Diameter" column to determine your size.

Method 2: Measure the circumference of your finger using a piece of string or paper, and a ruler

  1. Wrap a piece of string or paper around the base of your finger.
  2. Mark the 2 strands of string or paper where they overlap to form a complete circle.
  3. Measure the length of the section of string or paper in mm, between the 2 marks.
  4. Compare your measurement with the chart below, in the “Circumference” column to determine your ring size.
