How to Measure Your Correct Ring Size

Thank you for choosing YophieMade for your ring purchase. To ensure that you find the perfect fit, please follow the instructions below on how to measure your ring size.

  1. Choose a Piece of String: Use a piece of string instead of paper or tape for a more accurate measurement.
  2. Wrap the String Around Your Finger: Gently wrap the string around the finger you wish to measure. Ensure it is neither too tight nor too loose.
  3. Mark the String: Mark the point where the ends of the string meet with a pen or marker.
  4. Measure the String: Lay the string flat and measure the length from the starting point to the mark with a ruler. Note the measurement in millimeters or inches.
  5. Determine Your Ring Size: Refer to the ring size chart below to convert the measurement to your corresponding ring size.
