How to Measure

Find Your Ring Size

Method 1: Measure a Ring

  • 1. Find a ring that fits comfortably on the intended finger.
  • 2. Measure the internal diameter (mm) of the ring, using a ruler or measuring tape.
  • 3. Find your size using our size chart above.

Method 2: Measure Your Finger

  • 1. Cut a piece string to a length of 10cm.
  • 2. Wrap the string comfortably around your finger where the ring should sit - this should not be pulled tight.
  • 3. Use a pen to mark the overlapping parts of the string.
  • 4. Lay the string flat and measure the string between the two marked points (mm).
  • 5. Find your size using our size chart above.

Expert Tips

  • 1. Measure the correct finger - the same finger on the opposite hand will often be a different size.
  • 2. Don't have string? A folded strip of paper will suffice.
  • 3. Always measure twice.
  • 4. Measuring in the afternoon when your hands are warm will give you the most accurate result.
  • 5. Oversized rings may require a larger size to ensure correct fitment.
  • 6. Contact Customer Service if you're unsure.
