To determine your ring size, follow the guide: 

  1. Use a piece of string and wrap it around the base of your finger.
  2. Use a pen to mark the point on the string where the end meets.
  3. Use a millimeter ruler to measure the string.
  4. Choose the closest measurement to the chart below to find your ring size. But do allow enough room to accommodate your knuckle.
