What's the average penis size when erect and when not erect?

Answer 1

It appears that many men are obsessed with their penises, even if they don't realize it. Most men live in constant fear that their manhood is not big enough. So what exactly is the "average” man packing between his legs, I hear you ask? According to a recent study, involving 800 men of all shapes, races, and sizes, concluded that the average penis size is 5.5 inches. The vast majority [around 85%] fall between 5-7 inches when erect. Bear in mind though that these measurements weren't taken in any scientific manner. Most were taken by the guys themselves and submitted, so you have to question the accuracy. One thing that is clear from the available statistics is that the size of a man when flaccid will have little bearing on his size when erect. Some men who are tiny when flaccid grow into monsters when the blood starts pumping.

Answer 2

On my own observation. I would say erect size is 4" to 7"; this would include about 90% of adult male population. For not erect, it would be hard to say because for a particular person not erected varies in size. Anyway erect size is what matters when it comes down to it.

Answer 3

Length of the unencumbered flaccid penis is not necessarily proportional to size of the erect penis. Blood flow from arousal, and its relationship to the subsequent length measurement of the erect penis varies widely among men. Hence a smaller-than-average flaccid penis might grow to five times its flaccid length and twice its girth, or conversely a flaccid penis on the larger side might only grow to 1.5 times the length when filled with blood. The transition to erection and its relationship to measurements is by no means a one-size-fits-all equation.[citation needed]

* A study published in the September 1996 Journal of Urology concluded that mean flaccid length was 8.8 cm (3.5 in)(Measured by staff).[4]

Low temperatures affect the size of the flaccid penis. One general physiological response to cold is decreased circulation of blood to the extremities, which includes the external genitals. The penis will often shrink further as a result.

Regarding the length of the adult fully erect penis (measured along the top of the penis from the groin to the tip), several studies have been performed. Studies that have relied on self-measurement, including those from Internet surveys, consistently reported a higher average than those that used medical or scientific researchers to perform the measurements.

Academic and scientific studies

* A study published in the September 1996 Journal of Urology concluded that average erect length was 12.9 cm (5.08 in)(Measured by staff).[4]

* A study published in the December 2000 International Journal of Impotence Research found that average erect penis length was 13.6 cm (5.35 in)(Measured by staff).[5]

Sample of college students on spring break

* A study conducted by LifeStyles Condoms during 2001 Spring Break in Cancún, Mexico, found an average of 14.9 cm (5.9 in) with a standard deviation of 2.1 cm (0.8 in)(Measured by staff).[6]

Self measurement surveys

* An Internet survey performed by Sizesurvey.com found an average of 16 cm (6.4 in).[7]

* An Internet survey performed by Jackinworld.com found an average of 15.6 cm (6.1 in).[8]
