Pulling data from 17 previous academic papers that included a total of 15,521 men worldwide, researchers in the UK came up with a meta-analysis of what they believe to be the average size and girth of a penis when erect and when flaccid. According to the new research in BJUI, the average flaccid penis is 3.61 inches in length and 5.16 inches in length when erect. Girth is 3.66 inches when flaccid and 4.59 inches when erect.
Numbers aren’t the only results to come out of the new study. It also questions some of the common penis size stereotypes, like whether your race or foot size are determining factors for penis size.
The researchers did not find enough evidence from the 17 previous studies to come up with a conclusion about the difference in size by race. Two studies incorporated foot size into account, and found penile length to be “significantly weakly correlated,” while the other did not find a correlation at all between the two.
The stronger statistically significant correlations were between flaccid stretched or erect length and height, which was found in four studies, although the correlations were not extremely strong.
Of course, there are a few limitations that could affect penile dimensions, including temperature, level of arousal and sperm count.
But we’re much more interested in what 3.61 and 5.16 inches actually looks like, so we’ve compared the two averages with everyday household objects. Read more…
