Many scientific researchers have tried to answer the question of men and women from all over the world who want clear information about: What is the average penis size?
Here we will present the data of all the scientific studies carried out on penis size so that, once you finish reading this article, you have the most accurate answer to this question. And you may feel calmer about the size of your penis or that of your partner.
The published findings are often presented with contextual information about men’s generalized anxiety about whether their penises are large enough or not, and if their sexual partners will feel satisfied. So what is the truth?
Given the high dissemination of free and easily accessible pornography on the Internet, as well as the increase in aggressive marketing by companies that promise a bigger penis through the use of penis extenders and enlargers, it is easy to see why the truth about Length and male genital circumference could have darkened.
It may not be so surprising that researchers constantly find that men have increased anxiety about their virility.
Basic facts about the average penis size
Here are some key points about the average penis size. In the main article you will find more details and support information.
- While 85% of women may be satisfied with the size and proportion of their partner’s penis, men feel less self-confident.
- Up to 45% of men believe they have a small penis.
- In all studies, the length when flaccid ranges between 7 and 10 centimeters (2.8 to 3.9 inches), on average.
- The average circumference or contour in that same state ranges between 9 and 10 centimeters (3.5 to 3.9 inches).
- The length when erect ranges, on average, between 12 and 16 centimeters (4.7 to 6.3 inches).
- The circumference in that same state is about 12 centimeters (4.7 inches).
How big would a penis be to be considered small?
Perhaps the best indicator of what is considered is a small penis lies in the threshold that doctors use to be able to consider penis enlargement.
Researchers who published in the Journal of Urology studied the penis size of 80 “physically normal” men, measuring penis dimensions before and after drug-induced erections.
After finding the average sizes, they concluded:
“Only men with a flaccid penis with a length of less than 4 centimeters [1.6 inches] or an extended or erect penis with a length of less than 7.5 centimeters [3 inches] should be considered candidates for penis enlargement.”
How big is a ‘normal’ or average penis?
In the Journal of Urology study, researchers found the following among the group of 80 men:
- average penis size was 8.8 cm (3.5 inches) when flaccid
- The average penis size was 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 have different lengths when they are flaccid can have erect penises of a similar size. Nor was a relationship found between the ages of men and the size of their penis.
The finding about how much penis length can ‘grow’, whether it is flaccid or erect, was supported by a study of 200 Turkish men, in which “flaccid penis length was of little importance in determining erect penis length” .
Research to determine the average penis size includes a study published in January 2014 that examined more than 1,600 American men, although it did not take independent physical measurements.
Instead, the study was based on men’s own penis size measurements. However, the reports can be considered quite reliable, since men were given condoms to compare them with the measurements they reported, which means that any inaccuracies would have resulted in poorly adjusted prophylactics.
This study found that the average penis measurements are as follows:
- The average penis size when erect is 14.2 cm (5.6 inches)
- The average girth of the penis when erect is 12.2 cm (4.8 inches)
The researchers said the dimensions of the erect penis they reported were consistent with the findings of other studies. This study added the finding that the exact dimensions of an erection can be affected by the way you get excited; For example, if a man is stimulated by hand.
To measure penis length, press a ruler in the groin and measure from the base of the penis to the tip.
To measure the circumference of the penis, surround the widest part of the penis with a measuring tape.
Several studies have suggested an average penis size between 5.1 and 5.6 inches.
Penis size: women seem to care less than men
Men’s concern about whether the size of the penis meets the wishes of women seems to be largely misplaced.
And unfounded worries about insufficiency are made worse by the fact that a man’s judgment on his penis automatically makes him appear smaller to him than to another person.
Looking at the penis from above makes it appear smaller, compared to its appearance from the front or from the side.
Seeing your own penis from this perspective and perhaps comparing it to that of other men from a different perspective could, therefore, reinforce false ideas about penis size. But do women have a more reliable perception?
A study, published in the British Journal of Urology International, suggested that, although most women (about 85%) felt satisfied with their partner’s penis size and proportion, men felt less confident than themselves.
Almost half of the men in the study (45%) believed they had a small penis; However, the researchers reported that the size of a small penis is very unusual.
Some 170 women answered questionnaires in another study, which found that, although they attached some importance to penis size, it was only a “substantial” importance for a “clear minority” of women.
While most men’s concerns about penis size focus on length, women are more interested in width, according to one study.
The study of 50 sexually active university students reported that, for the vast majority, 9 out of 10 women, penis width was more important for sexual satisfaction than length.
Women do not want men with big penises
A study published in the open access journal PLOS ONE in November 2015 adopted the novel approach of asking women to show their penis size preferences with the use of 3D printed models of 33 different dimensions.
Women were asked to choose between 33 3D-printed ‘penises’ of different sizes, including the examples shown here. The largest in the set was A, while D was the smallest; the color blue was used because of racial neutrality. Image: Nicole Prause et al.
The sizes were printed in a range of 4 inches to 8.5 inches long and 2.5 inches to 7.0 inches in circumference, according to previous studies that establish an average penis size in Americans when it is erect 6 inches (15.2 cm) long with a circumference of 5 inches (12.7 cm).
For the axes in the 3D printer, blue plastic was used to not suggest any particular breed that could harm women’s ideas about the average size.
The 75 women who indicated the size preferences of the 33 blue models chose somewhat differently depending on the type of relationship they thought about (and in any case they showed that they wanted a size that turned out to be only slightly above the averages found in the studies):
- For long-term sexual partners, they opted for a penis of slightly smaller circumference and length compared to their choices for casual encounters, choosing an average length of 6.3 inches and a circumference of 4.8 inches.
- instead, his preference for casual sexual partners was 6.4 inches in length and 5.0 inches in circumference.
More about penis measurements
Several studies have tried to determine the average penis size. One published in 2001 took measures from 3,300 young Italians between 17 and 19 years old.
He found that the average median length of penises in a flaccid state was 9 centimeters (3.5 inches), and the circumference in a flaccid state (in the middle of the axis) was 10 centimeters (3.9 inches).
Another study examined a different population, 301 physically normal Indian men, and sought to compare their results with size findings in other countries.
The results, according to the authors of the 2007 study, “will help advise patients concerned about the size of their penis and seek an enlarged surgery.”
- Flaccid: the median average length was 8.2 centimeters (3.2 inches) and the circumference (of the flaccid penis stretched) was 9.1 centimeters (3.6 inches).
- Erect: the median average length was 13.0 centimeters (5.1 inches) and the circumference was 11.5 centimeters (4.5 inches).
The findings, published in Nature, included a table listing previous findings about penis dimensions worldwide. Click here to see the table.
Of the 16 studies from several countries that cited, the first was conducted over a hundred years ago and was published in 1899.
All concluded in similar average penis lengths:
- The lengths in flaccid state ranged from 7 to 10 centimeters (2.8 to 3.9 inches).
- flaccid circumferences ranged from 9 to 10 centimeters (3.5 to 3.9 inches).
- erect lengths ranged from 12 to 16 centimeters (4.7 to 6.3 inches).
- the circumference in an erect state (only a previous study) was about 12 centimeters (4.7 inches).
Major concerns, “wrong” wishes for enlargement
The authors of the study from India wrote that the definition of normal penis size was of “considerable interest” since there was a “steady increase in the number of people who complained of ‘small penis’ and sought enlargement procedures.”
Other research has suggested that most men seeking surgery to lengthen their penis have an overestimated perspective of what a normal penis size is.
In the study of 67 men who complained about a short penis, in fact, none turned out to have a severely small penis. The authors said there was a growing number of men seeking surgery to lengthen their penis.
Only a small effect of obesity and age on erect penis size
In 2015, researchers in Saudi Arabia published the results of a retrospective cohort study of 778 men with an average age of 43.7 years (with a range of 20 to 82 years) who attended external urology consultations in the country.
Men under 18 years of age, who presented with a complaint of small or short penis, with Peyronie’s disease, congenital curvature, clinical hypogonadism, previous surgery or penile trauma, or a combination of any of these were excluded from the study.
After medically inducing an erection, the researchers took measurements and averaged:
- Penis length of 12.53 centimeters (4.9 inches) from the skin over the pubic bone to the tip.
- Penile length of 14.34 centimeters (5.6 inches) from the pubic bone to the tip.
- penis circumference of 11.50 centimeters (4.5 inches).
The researchers also measured the body mass index (BMI) of men, which increases with obesity. There was a weak correlation between a higher BMI and shorter erect penis length when measured from the skin over the pubic area, but not when measured from the bone to the tip.
This suggests that the penis would appear to be shorter when there is more fat under the skin at its visible base.
This study also showed a weak correlation with increasing age in terms of the dimensions of the erect penis.
However, the authors noted that small decreases in size could be a concern that is limited to “elderly men”; They found that “the difference between 70 and 20 year old men was less than a centimeter.”
