What is the average penis size?


When it comes to the size of their penis, it's no secret that men tend to exaggerate. This is nothing new. It's been going on for decades, centuries, no doubt millennia.

Not surprisingly this leads to a lot of concern about men as to whether or not they measure up in the manhood department.

in 2007, Dr Kevan Wylie from the Porterbrook Clinic and Royal Hallamshire Hospital in Sheffield and Ian Eardley from St James’ Hospital in Leeds worked together to study the collective findings of more than 50 international research projects into penis size and small penis syndrome carried out since 1942. Their findings were then published in the British Journal of Urology.

By drawing together the results of 12 studies that measured the penises of 11,531 men, they discovered that average erect penises ranged from 14-16cms (5.5 to 6.2 inches) in length and 12-13cm (4.7 to 5.1 inches) in girth.

So, according to the scientific research, the average size of an erect penis is between 5.5 and 6.2 inches long - and given that some of those surveys may have been compromised by self-reporting and self measuring, it's probably safe to assume that the average penis is between five and six inches long.
