Follow these instructions to measure the circumference (girth):

  • Use a soft measuring tape or a piece of string.
  • If you choose the latter, make sure it doesn’t stretch.
  • Gently wrap the tape or string one time around the thickest part of the erect, or semi-erect penis.
  • Mark where the ends of the string or tape meet.
  • Stretch out the string or tape and use a ruler to measure the distance from one end to the other.
  • This measurement should give you the girth of your penis.
