The size and external shape of the penis have always been the subject of discussion and even concern in the male gender, since it is the part of the body associated with man’s virility.

In this sense, the shapes and sizes are very varied and are more related to the genetic component.

In the following article, we give you the necessary information about the types, characteristics, and peculiarities of this organ that is so important to man.

penis sizes

To determine the size of the penis, it is taken from the pubic bone to the tip of the glans penis on the upper side of the penis.

To be accurate in the measurement, all the fat that could be above the pubic bone is compressed and the millimeters that the foreskin could add are discarded. The following are the most common penis sizes:


A scientific article in the British Journal of Urology International establishes that the average length of a flaccid penis is 9.16 centimeters, while it reaches 13.12 centimeters when erect. Regarding the circumference, the average is 9.31 centimeters in periods of non-arousal and 11.6 centimeters in erection.

Note: This average may vary, even up to 15 (5.9 inches) centimeters in a state of erection, according to the selected population.


These are considered exceptional cases , where a penis that reaches a length of 16 centimeters when erect falls in the 95th percentile, it is considered outside the average.

Note: The world average size is between 14 centimeters (5.51 inches) and 16 centimeters (6.2 inches) centimeters in arousal. A large penis is considered when it is above the world average.


When the penis is much below average in size, it is known as a “micropenis” and measures less than 5 centimeters in the erect state. This can happen because the level of the male hormone testosterone was too low during fetal development.

Important: In an article in the Mexican Journal of Urology, the hormonal deficit of testosterone or gonadotropic hormones is established as one of the incident factors in the formation of the micropenis .

Types of penises

Due to our genetic variety, the conformation of our organism undergoes characterizations that are not necessarily related to ethnicity or race. This includes the morphology of the penis . Here we show you the different types of penises that have been registered:


A penis is considered to be straight, when in an erect state little or no deviation is observed throughout its body, to any side (left, right, up or down).


This type of penis maintains this curved shape even when erect , to one side or the other. The relative advantage of the curved type of penis is that it could favor the stimulation of the woman’s G-spot , but different positions would have to be tried depending on the curvature.

To highlight: There is a syndrome called “peyronie”. In this condition, fibrous scar tissue develops inside the penis, causing it to curve during erection.


This type of penis is totally straight, thin and elongated , with a larger size and when it reaches a full erection they get a lot of firmness. Being very elongated, it usually stimulates the entire wall of the vagina evenly.


When talking about the thickness of the penis, we usually refer to the contour of the penis, that is, the diameter. The average thickness of the penis in adults is between 12 and 14 centimeters , but as with the length of the penis, in this aspect they present with notable geographical differences.

Note: A penis thicker than 18 centimeters is already unusual and in most discussions is considered painful for a woman during sexual intercourse.


This shape of the penis is characterized by a narrow glans penis and a smaller thickness, regardless of the size, it is rectilinear, and in the sexual act, it stimulates the vaginal walls equally.


One of the parts of the penis is the foreskin and includes the skin that covers the penis. The circumcised penis is one in which the foreskin has been surgically removed . This type of penis is usually less sensitive as it does not have this skin that covers the glans, since it is slightly hardened to prevent damage.

not circumcised

In this case, the layer of skin that covers the glans has not been removed . The uncircumcised penis is the one that maintains the foreskin. It does not represent an impediment of any kind when having intimacy.


The characteristic of the mushroom penis is that it has a very prominent glans compared to the size of the body.

Note: This type of penis should not have any problems for penetration and arousal during sexual intercourse, although if the vagina is very tight, it may require a little lubrication.


Unlike the mushroom penis, the cone-shaped penis has a broad base size and a smaller glans penis. This type of penis should not have any type of restriction at the time of intimacy and favors positions where the penis reaches deep penetration.


This type of penis is characterized by inaccuracy at the time of erection. It may be that on one occasion it reaches a certain size and on other occasions its erection size is different.

Note: Also known as an unpredictable penis, as there is no way to predict how big it will get each time.

Considerations about penis sizes

The size of the penis has given rise to a series of conjectures, theories and speculations, which we will mention below:.

They do not influence sexual performance

The literature that discerns about the size of the penis indicates that the man is the person most concerned about the size of his own penis, with little concern on the part of the couple.

One study concluded that objectively informed advice about penis size could be effective in alleviating the concerns of most men about the size of their penis.

Another study reveals that men with more sexual experience tend to speculate about the size of their penises than men with no prior sexual experience.

Note: The lack of information is in this regard, one of the main causes of depressive states in men.

The size in erection is not the same in flaccidity

When the penis is flaccid , the corpus cavernosum is empty. In a state of arousal, this cavernous body fills with blood, and this is what causes an erection .

Highlights: A study on “Increase in Penile Size Between Flaccid and Erect States: An Analysis of the Kinsey Data” , reveals the difference in measurements of penises in flaccid and erect states.

Varies by ethnicity

There is no conclusive evidence that proves the relationship of men belonging to ethnic groups or countries with the size of the penis, but institutions such as the World Health Organization have revealed slight ethnic differences in the average size of the erect penis.

Fun fact: In Europe, the average penis size for men in the UK and Turkey is the same (13.97 centimetres).

They do not relate to the size of the feet and hands

There is no scientific evidence or literature to support this statement. However, there is an article in the Asian Journal of andrology, on “Ratio of the second to fourth digit: a predictor of penile length in adults” , in which it states that the ratio of digits can predict the size of the adult penis .

They can be modified with surgery and treatments

There are several surgical and aesthetic techniques that promise to increase the size of the penis, but many of them barely manage to produce a small change, without generating the expected result. This is because the size is determined by genetics. This requires a very high diffusion.

Note: One study concluded that only men with a flaccid length less than 4 cm, or a stretched or erect length less than 7.5 cm. should be considered candidates for penis enlargement.

In the same way, a study on “Systematic review of surgical and non-surgical interventions in normal men who complain of small penis size” , concludes that injectables and surgery should remain the last option , considered unethical outside of the clinical trials.

Key Findings

  • There are a wide variety of sizes and types in terms of penis morphology.
  • Size is not related to ethnicity or race.
  • Its main component is genetics.
  • Its size modification is not advisable , except in exceptional cases and under the supervision of a specialist.
