1. Take a thin strip of paper or string and wrap it around the base of your finger. Make sure the measurement can slide through your knuckle if you know it is on the larger side. 2. Mark the point where the paper strip or string first overlaps with a pen. 3. Measure the length between the marked point and the end of the paper strip or string on a ruler in millimetre (MM). 4. Repeat steps 1-3 for two to three times for accuracy of measurement. Note: Since your finger size varies with your temperature, it is recommended to take your ring size measurement in the afternoon.
