If you’re someone with a penis, you’ve undoubtedly wondered how large yours is in comparison to the average.

You don’t need to wonder any longer, as researchers publishing in BJU International have studied over 15,000 penises to figure out the average penis size.

The study was titled “Am I normal? A systematic review and construction of nomograms for flaccid and erect penis length and circumference in up to 15 521 men” and the objective of the study was to “systematically review and create nomograms of flaccid and erect penile size measurements.”

Noting that many men experience “small penis anxiety” or “small penis syndrome” despite their penis falling within a normal range, the researchers suggest their results will help to alleviate anxiety around the issue.

According to the researchers, the average penis length is just over 13 centimeters, or around 5 inches. Furthermore, there’s no strong correlation between hand size and penis length, so women can stop judging men by the size of their hands.

Previous research studies into average penis size have usually relied on self-reporting, which isn’t very accurate. To avoid this problem, the researchers compiled measurements taken by health practitioners who measured both girth (the circumference at the base and middle) and length (pubic bone to the tip of the glans). They compiled measurements from 20 different studies, eventually including 15,521 different penises in the study from countries around the world.

The results will be music to the ears of many men all over the world.

The average flaccid penis was found to be 9.16 cm (3.61 inches) long, while the average erect penis is 13.12 cm (5.16 inches) in length. As for girth, the average circumference of a flaccid penis turned out to be 9.31 cm (3.66 inches), and 11.66 cm (4.59 inches) for an erect one.

Moreover, it was found that those at extreme ends of the spectrum were more uncommon than expected. For example, only 5 men out of every 100 have an erect penis longer than 16 cm (6.3 inches).

The researchers looked for correlations between other body features such as testicular size, weight, and hand or foot size, but couldn’t find any meaningful correlations. They also couldn’t find any significant correlation between penis size and race, but the researchers noted that most of measurements were taken from Caucasian men.

What’s the key point of the research results?

Men, don’t be so hard on yourself. The penises you’re inevitably seeing in porn are extremely rare and are not an accurate representation of the average penis.

Small penis anxiety is a real thing, and these results will do much to combat it.
