How to determine your ring size

  1. Wrap a piece of string or a strip of paper around your finger.
  2. Mark the point where the two ends meet.
  3. Measure the string or paper against a ruler to get the circumference of your finger.
  4. Divide that by 3.14 to get the diameter of your finger.
  5. Look up your ring size using the chart below.
