How to Measure Your Ring Size

  1. Wrap a thin strip of paper or a piece of string around your finger.
  2. Mark where the paper or string overlaps.
  3. Measure the length in millimetres — this is your circumference.
  4. Match your measurement to the chart above.

Tip: Measure your finger at the end of the day when fingers are at their largest.
