Average penis size. There are no average length figures for teenagers because people grow at different rates. For adults, the average penis size is about 14-16cm (5.5-6.3 inches) when erect. The average girth for an erect penis is 12-13cm (4.7-5.1 inches). A penis would only be considered unusually small if it was less than 3 inches (7.6cm) long when erect. The measurements are based on a review of 50 studies on penis size conducted since 1942, which between them have measured 11,531 penises.
