Size Guide

The art of penis measuring.

In order to follow these steps you'll need to print out our size guide or use a ruler that you have at home.   

How to measure the flaccid length

  1. Grip the glans of your penis.
  2. Pull it as far outward as you can (without hurting yourself).
  3. Find the bone at the left or right of the base of your penis.
  4. Take the size guide and press the edge of it against that bone.
  5. With your penis still stretched out, line up your penis next to the size guide keeping both size guide and penis completely parallel to each other.
  6. Measure by tracing the tip of your penis to the correct mark on the size guide to get your size.

How to measure the erect length

  1. Get your penis to the 100% erect state (you probably know best how to achieve this).
  2. Find the bone at the left or right of the base of your penis.
  3. Take the size guide and press the edge of it against that bone.
  4. Angle and steady your erect penis so that it’s completely parallel and lined up next to the size guide.
  5. Measure by tracing the tip of your penis to the correct mark on the size guide to get your size.

How to measure girth

  1. Take the size guide in one hand.
  2. With your penis erected, wrap it around the thickest part of your penis shaft.
  3. Make a note of where the first overlap occurs – this is your girth measurement.

    If you don’t have access to a printer in order to print the size guide you can always use any tape-like tool that you have in your household.
