Tips for Measuring

  • Measure your finger at the end of the day when it’s largest.
  • Avoid measuring when your fingers are cold, as they can be smaller.
  • For a more accurate measurement, repeat the process multiple times.

If you are between sizes, it is generally recommended to go for the larger size.
