Dimensions Guide

One of the most interesting aspects of a penis is the length, which is basically measured with the subject standing while his penis is parallel to the ground. For a more precise measurement, it is best to measure it starting from the base all the way to the tip. Furthermore, it must be measured when fully erect in order to achieve a more accurate result. Understand this male reproductive organ by knowing the average penile length.

The Average Length of Penises

What is the average penile length? Based on numerous studies, the human penis has an average length of 12.9 to 15 centimeters or 5.1 to 5.9 inches. When fully erect, an average-sized penis is expected to have a circumference or girth of about 12.3 centimeters or 4.85 inches. At birth, the average length of a penis when stretched is 4 centimeters or 1.6 inches. An estimated 90 percent of newborn boys will have a penis measuring between 2.4 to 55 centimeters or about 0.9 to 2.2 inches. Penile length is expected to be slow between the time of birth and the age of five.

Additional Facts and Other Interesting Details

Thanks to the interesting nature of penile length, numerous researchers have allotted insurmountable amount of time and effort to come up with highly accurate approximations about the subject. In the September 1996 issue of the “Journal of Urology,” a study was featured concluding that the average penile length is 12.9 centimeters or 5.08 inches. This particular research was conducted in an effort to come up with guidelines of penile length for individuals who are considering penile enlargement.

Another significant study that focused on the average length of penises came in 2000. For that year, the “International Journal of Impotence Research” published in its December issue the results of a research on the penile length of Jewish Caucasian men, the result of which was 13.6 centimeters or 5.35 inches. LifeStyles Condoms also performed a study, in which the group found that the average penile length is 14.9 centimeters or 5.9 inches. In 2007, “BJU International” published an article showing that the average length of human penises is 14 to 16 centimeters while the girth is 12 to 13 centimeters.

It is important to determine penis size especially when buying condoms. Wearing the right size of condom is necessary because something that is too small can eventually lead to breakage, which defeats the purpose of wearing them in the first place. It is also not good to wear a condom that is bigger than the penis because of slippage.
