How to Measure Ring Size Accurately


  • Make sure you have printed the printable ring sizer at 100%, without page scaling. Use a ruler to check that the page has printed at full size.
  • Remember to measure across the knuckle of your chosen finger since this is the widest part of your finger.
  • Measure your finger in the evening, when it is biggest.
  • Always measure by pulling tightly to get the most accurate reading.

Ring sizes vary by country. If you already know your ring size and just need to convert it to another scale, see our International ring size conversion chart.
