How to Measure
Bone Pressed Erect Length
Penis length is defined as the linear distance along the dorsal side of the erect penis extending from the mons veneris to the tip of the glans. In non-medical terms, the penis length is measured in a straight line on the top side of the erect penis, from the start of your pubic bone to the tip of your penis. Penis circumference is defined as the linear distance around the widest, thickest, part of the erect penis (see below).
1. Stimulate yourself into the erectile state.
2. Place your ruler at the pubic bone, at the base of your erect penis and measure to the tip of your glans.
3. Read the nearest quarter-inch measurement at the tip of your penis. (In the example shown, the measurement would be 4 and 3/4 (4.75) inches.)
Bone Pressed Flaccid Stretch
1. Make sure you are in a completely flaccid state.
2. Place your ruler at the pubic bone on the side of the penis
3. Stretch penis straight out
3. Read the nearest quarter-inch measurement at the tip of your penis
Non-Bone Pressed Erect Length
1. Stimulate yourself into the erectile state.
2. Place your ruler at the skin on the belly, at the base of your erect penis and measure to the tip of your glans without pushing ruler.
3. Read the nearest quarter-inch measurement at the tip of your penis.
Flaccid Length
1. Make sure you are in a completely flaccid state.
2. Place your ruler at the skin on the belly, at the base of your flaccid penis and measure to the tip of your glans without pushing ruler.
3. Read the nearest quarter-inch measurement at the tip of your penis.
Penis Erect Circumference
Penis length is not the only factor in determining penis size. The width, girth, or fatness, of a penis is also an important aspect when considering how you compare. Most people have a penis that is either longer and thinner, or shorter and fatter. To compare how the girth of your penis compares to the population, use the instructions below to determine your penile circumference (distance around the widest part of your penis).
1. Stimulate yourself into the erectile state.
2. Place the fabric ruler or string end at the widest part of your penis and wrap it carefully around one time. Mark the spot where the string first touches itself.
3. If using string, take the marked string and lay it against the ruler. Read to the nearest quarter-inch measurement.
