What size is the average penis?

We will present you with facts from all the scientific studies done on penis size so that once you have finished reading this article, you will feel content that you have the most accurate answer to the question. And perhaps you will be reassured about your own size or that of your partner’s penis.

Published findings are often introduced with background information on men’s widespread anxieties about whether or not their penises are big enough, and if sexual partners are going to be satisfied. So what is the truth?

Given the ubiquity of free, easily accessible internet pornography, and the rise in aggressive marketing by companies promising a bigger penis through the use of extenders and enlargers, it is easy to see why the truth about male genital length and girth might have become obscured.

Perhaps it is no surprise, then, that researchers consistently find that men have heightened anxieties about their manhoods.

When is penis size too small?

Perhaps the best gauge of what is considered to be a small penis is given by the threshold used by doctors for when penile augmentation may be considered.

Researchers publishing in the Journal of Urology studied the penis sizes of 80 “physically normal” men, measuring penile dimensions before and after drug-induced erections.

After finding average sizes, they concluded:

“Only men with a flaccid length of less than 4 centimeters [1.6 inches], or a stretched or erect length of less than 7.5 centimeters [3 inches] should be considered candidates for penile lengthening.”

What is ‘normal’ or average penis size?

In the Journal of Urology study, researchers found the following among the group of 80 men:

• An average penis size of 8.8 cm (3.5 inches) when flaccid
• An average penis size of 12.9 cm (5.1 inches) when erect

The study also found that the size of a man’s erect penis was not correlated with the size of his flaccid penis.

This means that men whose penises are different lengths when flaccid may have similarly sized erect penises. There was also no relationship between the men’s ages and their penis sizes.

The finding on how much the penis length can ‘grow’ — on whether you are a ‘shower’ or a ‘grower’ — was further supported by a study of 200 Turkish men, in which “flaccid length had little importance in determining erect penile length.”

The research to determine average penis size includes a study published in January 2014 that examined over 1,600 American men, although it did not take independent physical measurements.

Instead, the study relied on the men’s own measurements of penis size. The reports may be considered fairly reliable, however, since the men were to be given condoms to match their self-reported measurements, meaning that any inaccuracy would have resulted in ill-fitting prophylactics.

This study found the average penis size to be as follows:

• Average size for an erect penis is 14.2 cm (5.6 inches)
• Average circumference of an erect penis is 12.2 cm (4.8 inches).

The researchers said the self-reported erect penile dimensions were consistent with findings from other studies. Their study added the finding that the precise dimensions of an erection can be influenced by the mode of getting aroused, such as whether a man uses hand stimulation.

To measure penis length, press a ruler into the groin and measure from the base of the penis to the tip.

To measure penis girth, wrap a measuring tape around the widest part of the penis.

Several different studies have suggested an average penis size of between 5.1 and 5.6 inches.
