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:
- 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.
- 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.
- Measure the length in millimeters. For thicker rings, consider sizing up slightly.
- Use our ring size chart to find your perfect fit.
That's it — easy, quick, and accurate!
