How to Measure Your Ring Size at Home

What You'll Need:
A pen, scissors, ruler, and either a flexible measuring tape or a piece of string.

Steps:

  1. Wrap the measuring tape or string around the base of your finger — snug but not tight. For best results, measure at the end of the day when your fingers are slightly larger.
  2. Mark where the ends meet or cut the string at that point. If using a ring sizer or tape, it should fit comfortably — not too tight to get stuck, but not so loose that it slips off.
  3. Measure the length in millimeters. For thicker rings, consider sizing up slightly.
  4. Use our ring size chart to find your perfect fit.

That's it — easy, quick, and accurate!
