According to the team’s analysis, the average flaccid, pendulous penis is 9.16 cm (3.61 inches) in length; the average erect penis is 13.12 cm (5.16 inches) long. The corresponding girth measurements are 9.31 cm (3.66 inches) for a flaccid penis and 11.66 cm (4.59 inches) for an erect one.
The researchers concluded that there was no strong evidence to link penis size to other physical features such as height, body mass index, or even shoe size. Yes, it seems that the only definite conclusion that can be drawn about a fellow with big socks is that he probably has big feet. Likewise, the study found no significant correlation between genital dimensions and race or ethnicity, although Veale points out that their study was not designed to probe such associations, because much of the data used were from studies of Caucasian men.
