How to Measure Your Ring Size

Method 1: Using a String or Paper Strip

  1. Cut a small strip of paper or a piece of non-stretchy string.
  2. Wrap it around the base of the finger you want to measure. Ensure it’s snug but not too tight.
  3. Use a pen to mark the point on the string or paper where it overlaps, forming a complete circle.
  4. Use a ruler to measure the length from the starting end of the string/paper to the pen mark in millimeters.
  5. Compare this measurement with the circumference values in the size chart to find your ring size.

Method 2: Using a Ring You Already Own

  1. Select a ring that fits the finger you’re buying the new ring for.
  2. Use a ruler to measure the inside diameter of the ring in millimeters.
  3. Compare this measurement with the diameter values in the size chart to find your ring size.

Method 3: Printable Ring Sizer

  1. Search online for a printable ring sizer and print it at 100% scale.
  2. Follow the instructions to cut out and use the sizer, usually by wrapping it around your finger and reading off the indicated size.

Additional Tips:
  • Measure your finger at the end of the day when it’s likely to be largest.
  • Avoid measuring when you’re cold, as fingers can shrink.
  • If you’re between sizes, go with the larger size.
  • For rings with wider bands, consider going up a half size.
  • If your knuckle is larger than the base of your finger, measure both places and pick a size in between.

For the most accurate measurement, it's always best to visit a jeweler. Many online jewelers also offer free ring sizers or sizing kits.
