Steps to Measure Your Ring Size
  1. Wrap a string or a strip of paper around the base of your finger, just below the knuckle. Make sure it's snug but not too tight.
  2. Mark the point where the string overlaps with a pen or pencil.
  3. Lay the string flat on a ruler or a straight edge and measure the length from the mark to the end of the string.
  4. Enter your measurement below (between 49-77mm) to find your ring size.
