How to Measure Your Ring Size

  1. Using a Ring You Already Own: Measure the inside diameter of a ring that fits comfortably and match it to the chart above.
  2. Using String or Paper: Wrap a thin strip of paper or string snugly around your finger, mark where it overlaps, measure in millimeters, and compare to the chart.
  3. Tips: Measure at the end of the day when fingers are at their largest, and ensure the ring can slide over your knuckle comfortably.
