Length of the flaccid penis does not necessarily correspond to length of the erect penis some smaller flaccid penises grow much longer, while some larger flaccid penises grow comparatively less. A review of several studies found average flaccid length to be 9–10 cm (3.5–3.9 in). One study (published in 1996) found the mean flaccid penis length to be 3.5 inches (8.9 cm) (measured by staff). Erect lengths in the included studies were measured by pushing the pre-pubic fat pad to the bone, and flaccid or erect girth (circumference) was measured at the base or mid-shaft of the penis. of medical research on the topic over the previous 30 years published in BJU International showed similar results, giving mean flaccid, stretched non-erect, and erect lengths of 9.16 cm, 13.24 cm, and 13.12 cm respectively, and mean flaccid and erect circumferences of 9.31 cm and 11.66 cm respectively. An adult penis with an erect length of less than 9.3 cm (3.7 in), but otherwise formed normally, is referred to in medicine as a micropenis.Īdult male erection in the mean range, measuring 14 centimetres (5.5 in)Ī 2015 systematic review published by Veale et al. Flaccid penis length can sometimes be a poor predictor of erect length. A 1996 study of flaccid length found a mean of 3.5 inches (8.9 cm) when measured by staff. As of 2015, a systematic review of 15,521 men, who were measured by health professionals rather than themselves, concluded that the average length of an erect human penis is 13.12 cm (5.17 inches) long, while the average circumference of an erect human penis is 11.66 cm (4.59 inches).

Measurements vary, with studies that rely on self-measurement reporting a significantly higher average than those with a health professional measuring. Most human penis growth occurs in two stages: the first between infancy and the age of five and then between about one year after the onset of puberty and, at the latest, approximately 17 years of age. Compared to other primates, including large examples such as the gorilla, the human penis is thickest, both in absolute terms and relative to the rest of the body. Besides the natural variability of human penises in general, there are factors that lead to minor variations in a particular male, such as the level of arousal, time of day, ambient temperature, anxiety level, physical activity, and frequency of sexual activity. Human penises vary in size on a number of measures, including length and circumference when flaccid and erect.
