It’s official….. the average penis size is 13cm (at least in the Western world)

At long last, a study to do away with much of the controversy about penis size and perhaps at the same time ease the problems shared by many people throughout the Western world, starting of course with Spain.

According to new research, the average length of the erect penis in Europe and around the North Western Hemisphere is little more than “13 centimetres”, or about 5 inches. Moreover, the same study highlights that there is no decisive association between foot size and length of the penis, so women can stop judging men by the size of their shoes.

You can read the full study in BJU International.

Although many men claim to be within an average size of penis, this can be a bit misleading, or at least difficult to sustain on the basis of this new research on a global scale. As noted in Science, this may be because most studies are based on an “auto-response” survey, which may not be 100% accurate.

To solve this problem and get a more reliable set of data, a team of researchers from the United Kingdom decided to compile measurements taken by health professionals, who have all followed a standardized measurement procedure.

Including both thickness and length measurements from 20 different studies, representing a total of more than 15,000 samples, the outcome is a downward revision of what is usually considered the average size of the erect member, outside the scientific world.

Here are the current official data:

The average penis SIZE:

• In a state of relaxation or FLACCIDITY is 9.16 cm (3.61 inches)

• in an erect state is 13.12 cm (5.16 inches) long.

The average THICKNESS of the penis (measured by the size in circumference)

• The average circumference of a flaccid penis was found to be 9.31 cm (3.66 inches)

• For its erect state it is 11.66 cm (4.59 inches).

In addition, and this is the really interesting part, extremes of the spectrum turned out to be much less common.

“Only five of every 100 men have an erect penis more than 16 cm (6.3 inches) long”.

When they looked for correlations with other characteristics of the body, such as testicular size, weight or foot size, they were unable to establish consistent correlations.

As for races, this study cannot find any significant evidence of a link between penis size and race, as the vast majority of measurements were white (Caucasian).

So what are the conclusions? Perhaps the primary conclusions are, as we have mentioned on other occasions, that we should stop being so hard on ourselves because of what we see on the internet or in magazines as this is not an accurate representation of the average penis. But if you still feel concerned, bear in mind there are reliable and durable surgical methods that can help enlarge your penis at least lengthwise, as it is a fact that there are no lasting methods for increasing thickness, at the moment.

I’m 19 and my penis is only 5.2 inches erect. I’m kinda chubby so I don’t if losing weight is gonna add to its size, I’m happy with its thickness, though. Please help

Hi Anonymous, the penis enlargement surgery it´s the most realiable and effective (and safe) way to add between 1,5 and 3cm large, mostly in cases that the grith it´s not the main problem.
