“We also hope that no man will be subject to physical treatment without a clear understanding of where he sits in the normal range. It is not uncommon for discussions behind the scenes for height and penis size to be compared. “We hope that these results will be of help to reputable clinicians who can use them to help reassure men with normal penis size they are indeed normal,” Muir said. Men may suffer psychological harm and relationship difficulties as a result of worrying about their size, and potential surgical “remedies” may be dangerous and are often unsatisfying, he said. “And research shows that women are rarely concerned about the penis size of their partner, rating it much less important than many other factors.”

“Many men with a 9 cm (3.54 inch) erection will have no problems having mutually satisfactory sexual relations, and few men with a longer than average penis seek medical help,” he said. Penis size is just like nose size a very tall man might have a small nose and a short man might have a big nose. Other researchers have suggested that the smallest 2.2% of the population should be eligible for penile augmentation surgery, which would include those with flaccid length up to 2.36 inches (about 6 cm).īut defining “too big” or “too small” still hasn’t been firmly nailed down, Muir said. Penis size is proportional to height, hand size or foot size Penis size is not related to height, hands or feet. Technically, less than 1% of the male population has a “micropenis,” which in this group included men with flaccid length below 2.04 inches (about 5 cm). “A bit like shoe size, really!”Īs far as how one man compares to another, according to the distribution graphs the authors plotted, men in the 90th percentile for erect length were upwards of 5.9 inches long (about 15 cm), and some of the longest penises in the study were more than seven inches long erect (about 18 cm). “There is not a ‘right’ penis size for a man of any height, just a range of ‘normal,’” Muir said. Erect penis length and overall height did seem to be related at least somewhat, however – taller men had longer penises. Stretched flaccid length was often very similar to erect length, the authors found, which may be good news for men and their doctors since clinical measurements of the erect penis may not be necessary.Ĭomparing these measures to other physical qualities, like age, body mass index or foot size, the authors found little or no association. The average flaccid penis was 3.58 inches long (about 9 cm) and 3.66 inches in girth, while the average erect penis was 5.16 inches long (about 13 cm) and 4.59 inches in circumference (about 11.7 cm), according to results online March 2 in BJU International.

Using more than 20,000 measurements of flaccid length, stretched length, erect length and flaccid and erect circumference, collected by health professionals for other studies, the researchers plotted the distribution of measurements to find the average.
