A survey of 300 men over the age of 18 carried out between 11 March and 17 March 2001 in Cancún, Mexico, found that among those men the average erect human penis was about 14.928 centimetres (5.877 inches) long, and that most of them had an erect penis length of between 14 and 16 centimetres (5.5 and 6.3 inches). The typical girth or circumference (the length around the outside of the penis) was about 12.63 centimetres (4.972 inches), and most erect penises had a girth of between 12 and 13 centimetres (4.7 and 5.1 inches). As this survey was only done in one city, its findings may not apply to men from other countries.
