Human penis size - Wikipedia, the free encyclopedia
Penis length is typically measured with the subject standing and the penis held parallel to the floor. Measurement of length goes horizontally along the top of the penis from the penis's base to the tip. If the penis is measured along the bottom or underside, the result is less reliable. Measurements taken while sitting or lying down also tend to be unreliable.
