Penis size is a great concern for a lot of people, every man has wondered if his size is normal or not. Porn, myths and exaggeration (specially on the net) are making people less confident about the sizes of their penises, and true information is not that easy to find on on line. This section has the aim to show some serious studies on the issue, most of them carries out by professionals, and give a realistic idea about what is Average and therefore normal.

For more information about scientific studies about penis size visit penissizestudies, where detailed information is provided for most of the studies published to date..

First we start with this table in which 21 flaccid penis size studies are shown:

Note that the first two as well has the study carried by Dr Acuña refer to self reported measures, while the rest are measured by professionals.

As a first approximation we can see from these studies that the average penis size in flaccid state is 9.1cm (3.6′) long and 9.6cm (3.8′) thick (circumference at the thickest point), but due to the great disparity of the averages [7.76-11.76] it would be more realistic to say that average flaccid penis size is somewhere between 8.5 and 9.5 centimiters (3.3-3.75 inches) and between 9 and 10 cm (3.5-3.9 inches).

This chart shows studies on erect penis size:

It is even more evident here how self reported surveys give statistically larger averages that those studies done by professionals. The average shown in yellow takes into account the size of the population studied, so these studies rise the average by being the biggest. That’s why we shouldn’t say anything else than the average erect penis size is somewhere between 14 and 15 cm long (5.5′ – 5.9′) and between 11.5 and 12cm thick.

Summing up we can say that a real men penis size is difficult to find due to the variability of penis size and the lack of good and big studies.
