Method 2: Measure your finger

  1. Cut a strip of paper or use a measuring tape

Helpful tips

  • Measure your finger at the end of the day, when your fingers are at their largest
  • Measure multiple times to ensure an accurate reading
  • Take ring width into account - wider rings fit more snugly
  • If in doubt between two sizes, choose the larger size
