📏 How to Measure Your Ring Size

Option 1: Measure an Existing Ring

  1. Choose a ring that fits the intended finger well.
  2. Use a ruler to measure the inner diameter in millimeters (mm).
  3. Refer to the chart below to find the corresponding China (CN) size.

Option 2: Use a Paper Strip

  1. Cut a thin strip of paper or string.
  2. Wrap it around the base of your finger (not too tight or too loose).
  3. Mark where the ends meet, then measure the length in millimeters (this is the circumference).
  4. Match the measurement with the chart below.

Tip: Measure your finger at the end of the day when it is slightly larger. Avoid measuring when your hands are cold.

💡 Ring Sizing Tips

  • Wider rings may require a slightly larger size for comfort.
  • Finger size can fluctuate due to temperature and time of day — measure when your hands are warm.
  • Rings should fit snugly at the base of your finger without sliding off easily.
