Average Penis Size By Country
Presenting the average penis size by country. Feel free to use our interactive charts to give you an idea how you measure up with the rest of the world. We also provide an informative images and videos that answers frequently asked questions about penises.
Penis size is a topic which is discussed a lot when it comes to sexual relationships and their importance. In a relationship, the man is for the most part considered the stronger in the relationship and hence their penis size becomes an important thing. There are basically three different schools of thought related to this issue.
In the table below you will find the average penis size by country in inches and centimeters. All studies done on the measurement of the penis have a strong indication that the average penis size worldwide is in the range of 12.9 to 15 centimeters or 5.1 to 5.9 inches. The shortest average size being 10.7 centimeters and the longest 19.1 centimeters (4.23 in. and 7.53 in.)
Now all this talk leads to one question. The question is, WHAT IS THE AVERAGE PENIS SIZE? Well, if you have read some articles on the internet or some social media websites you would have found different answers to this question. There are different points of view and plenty of research that has been done to answer this very question in particular. In this article, we will sum up some of the most accurate facts to answer this question in an unbiased way.
First let’s look into the positive and negative factors that affect the size of a penis. For example, hormones are very important when it comes to penal growth and size. The hormone related to the growth and size of the penial tissue is called Testosterone. This is probably the most important and positive factor that determines the size of penes.
The main culprit that plays a negative role in the growth or size of men’s penises is smoking. Men who smoke are always in danger of reducing the size of their penis. There are reports that have statistically proved that smoking affects penial size.
As a man, if you feel or think that you don’t have an average size penis or that your penis is too small you may begin to suffer from low self-esteem. It may be that your spouse or significant other is not happy with the size of your penis; that can be a great disappointment for you as well.
There are many different penis size and shapes that occur naturally in men. Something that cannot be controlled except through surgical procedures. According to the many scientific studies that have been done, the average size of penises is estimated to be 5.2 inches while erect. The circumference being roughly 4.6 inches.
Most men fall in that size range. On the other hand, there are some who have micropenis condition with a 2.6-inch size penis when fully erect. Micropenis is the medical term used for men with this size penis. On the other hand, there are some men who have a longer than normal penis. This condition depends on the part of the world in which they were raised. The environment and conditions in which a man lives can affect the growth of each and every part of their body including the penis. There is also evidence that some environmental factors including genetics contribute to the length and size of penial growth.
There is a train of thought that says that it doesn't matter what size penis a man has as long as he knows how to use it. But research says a different story. Women, they say, are happier with a penis size that is around 6.3 inches according to research stats gathered by a University in California.
Obviously, men and ladies from around the world, have a skewed impression of erect penis size. Female members speculated that the normal was 5.4 inches, while the men assessed a normal of 5.6 inches. Penis estimation likewise changed by nation. In Poland, individuals trusted the normal penis size was 6.2 inches in length while Brits said it was 4.9 inches. Indeed, even in the U.S. estimations were scattered, men from Maine had the biggest estimation at 6.5 inches; West Virginians gave the smallest estimations despite the fact that they were nearer to reality, at 5 inches.
Among all the 10 nations studied, individuals thought that the "perfect" penis was longer than the apparent normal penis. The U.S. had the largest gap between what the normal penis is and the perfect penis, with a distinction of 1.1 inches. In examination, those in the Netherlands were most fulfilled, trusting the perfect penis was 0.4 inches bigger than the apparent normal penis.
Is it possible to increase the size of your penis? There are many advertised methods, from male enhancement pills, penis enlargement devices (e.g. ProExtender™), to natural male enhancement treatments. But do all these methods really help when it comes to male enlargement? The straight, simple answer is, not really. See here for more information published by the Mayo Clinic.
Please understand that not everything that is advertised is necessarily safe and effective. Probably the most promising method is male enhancement surgery, but even this can be too risky and may not work for you. See what the Mayo Clinic has to say about surgical methods of penis enlargement and male enlargement pills.
Whether penis size truly matters or not really depends on the person you ask. As we saw there are various factors that determine the length of the penis. While many men think that they have a larger than average penis, the fact is that they really like to overestimate. This implies that we need a more accurate view with regards to the human body. We are daily bombarded by society and advertisement concerning this subject which impacts our perspective in a negative way. Making us pay too much attention to something that does not necessarily improve our lives, because chances are you have a normal size penis. It seems that men have been fed the wrong information as to what really makes him a man. Some men are obsessed with the idea of not measuring up to other man that all that is in their mind is, "Do I have a big dick?" or "How to get a bigger dick?" We apologize for using such crude words, but these are probably some of the most often searched queries online.

"Penis length" and "Small penis" redirect here. For differences in penis length among non-human species, see Penis § In different animals. For the medical term, see Micropenis.
Human penises vary in size on a number of measures, including length and circumference when flaccid and erect. Besides the natural variability of human penises in general, there are factors that lead to minor variations in a particular male, such as the level of arousal, time of day, room temperature, and frequency of sexual activity. Compared to other primates, including large examples such as the gorilla, the human penis is thickest, both in absolute terms and relative to the rest of the body.
Measurements vary, with studies that rely on self-measurement reporting a significantly higher average than those with a health professional measuring. As of 2015, a systematic review of 15,521 men, and the best research to date on the topic, as the subjects were measured by health professionals, rather than self-measured, has concluded that the average length of an erect human penis is 13.12 cm (5.17 inches) long, while the average circumference of an erect human penis is 11.66 cm (4.59 inches).[1] Flaccid penis length can sometimes be a poor predictor of erect length.
Most human penis growth occurs between infancy and the age of five, and between about one year after the onset of puberty and, at latest, approximately 17 years of age.[2]
A statistically significant correlation between penis size and the size of other body parts has not been found in research. Some environmental factors in addition to genetics, such as the presence of endocrine disruptors, can affect penis growth. An adult penis with an erect length of less than 7 cm (2.8 in), but otherwise formed normally, is referred to in medicine as a micropenis.
While results vary slightly across reputable studies, the consensus is that the mean human penis, when erect, is in the range 12.9–15 cm (5.1–5.9 in) in length.[3][4][5]
A 2015 systematic review published by Veale et al. of medical research on the topic over the previous 30 years published in BJU International showed similar results, giving mean flaccid, stretched non-erect, and erect lengths of 9.16 cm, 13.24 cm, and 13.12 cm respectively, and mean flaccid and erect circumferences of 9.31 cm and 11.66 cm respectively. Erect lengths in the included studies were measured by pushing the pre-pubic fat pad to the bone, and flaccid or erect girth (circumference) was measured at the base or mid-shaft of the penis.[1]
One study (published in 1996) found the mean flaccid penis length to be 3.5 inches (8.9 cm) (measured by staff).[3] A review of several studies found average flaccid length to be 9–10 cm (3.5–3.9 in).[6] Length of the flaccid penis does not necessarily correspond to length of the erect penis; some smaller flaccid penises grow much longer, while some larger flaccid penises grow comparatively less.[7]
The penis and scrotum can contract involuntarily in reaction to cold temperatures or nervousness, referred to by the slang term "shrinkage", due to action by the cremaster muscle. The same phenomenon affects cyclists and exercise bike users, with prolonged pressure on the perineum from the bicycle saddle and the straining of the exercise causing the penis and scrotum to contract involuntarily. An incorrect saddle may ultimately cause erectile dysfunction (see crotch pressure for more information).
Neither age nor size of the flaccid penis accurately predicted erectile length. Stretched length has correlated with erect length in some cases.[3] However, studies have also shown drastic differences between stretched and erect length.[8] One study found that a minimal tension force of approximately 450 g during stretching of the penis was required to reach a full potential erection length. this study also found that tension forces exerted in this study by the urologist were shown to be significantly (P<0.01) lower than 450g.[9] This may account for differences between stretched and erect length.
Scientific studies have been performed on the erect length of the adult penis. Studies that have relied on self-measurement, including those from Internet surveys, consistently reported a higher average length than those that used medical or scientific methods to obtain measurements.[5][12]
The following staff-measured studies are composed of different subgroups of the human population (in other words, specific age range or race; selection of those with sexual medical concerns or self-selection) that could cause a sample bias.[12][13]
Similar results exist regarding studies of the circumference of the adult fully erect penis, with the measurement usually taken mid-shaft.[6] As with length, studies that relied on self-measurement consistently reported a significantly higher average than those with staff measuring. In a study of penis size where measurements were taken in a laboratory setting, the average penis circumference when erect was 11.66 cm (4.59 inches).[1]
The average stretched penile length at birth is about 4 cm (1.6 in), and 90% of newborn boys will be between 2.4 and 5.5 cm (0.94 and 2.17 in). Limited growth of the penis occurs between birth and 5 years of age, but very little occurs between 5 years and the onset of puberty. The average size at the beginning of puberty is 6 cm (2.4 in) with adult size reached about 5 years later. W.A. Schonfeld published a penis growth curve in 1943.[19]
Authors of a paper reviewing research on area of penis sizes conclude that "flaccid penile length is just under 4 cm (1.6 in) at birth and changes very little until puberty, when there is marked growth."[2][6]
Age is not believed to negatively correlate with penis size. "Individual research studies have... suggested that penis size is smaller in studies focusing on older men, but Wylie and Eardley found no overall differences when they collated the results of various studies [over a 60 year period]."[6]
A 2015 review of the literature found two studies finding height and stretched or flaccid length to be moderately correlated, seven studies finding weak correlation for flaccid, stretched, or erect length, and two studies that found no correlation between flaccid length and height.[1]
One study investigated the relationship with digit ratio and found that men with longer ring fingers than index fingers had slightly longer penises.[20][21] However, the common misconception that hand size predicts penis size has been widely discredited.[22][23]
A statistically significant correlation between penis size and the size of other body parts has not been found in research. One study, Siminoski and Bain (1988), found a weak correlation between the size of the stretched penis and foot size and height; however, it was too weak to be used as a practical estimator.[24] Another investigation, Shah and Christopher (2002), which cited Siminoski and Bain (1988), failed to find any evidence for a link between shoe size and stretched penis size, stating "the supposed association of penile length and shoe size has no scientific basis".[25][26]
There may be a link between the malformation of the genitalia and the human limbs. The development of the penis in an embryo is controlled by some of the same Hox genes (in particular HOXA13 and HOXD13)[27] as those that control the development of the limbs. Mutations of some Hox genes that control the growth of limbs cause malformed genitalia (hand-foot-genital syndrome).[28]
The belief that penis size varies according to race is not supported by scientific evidence.[6][29] A 2005 study reported that "there is no scientific background to support the alleged 'oversized' penis in black people".[30]
A study of 253 men from Tanzania found that the average stretched flaccid penis length of Tanzanian males is 11 cm (4.53 inches) long, smaller than the worldwide average, stretched flaccid penis length of 13.24 cm (5.21 inches), and average erect penis length of 13.12 cm (5.17 inches).[31]
A recent 2016 study of 248 Korean men identified the average erect penis length to be 13.53 cm (5.33 in).[17] A study of 115 men from Nigeria found that the average flaccid stretched penis length of Nigerian males is 13.37 cm (5.26 inches) long, which is near identical to the worldwide average, stretched flaccid penis length of 13.24 cm (5.21 inches) and average erect penis length of 13.12 cm (5.17 inches).[32] A 2015 systematic review of 15,521 men found "no indications of differences in racial variability", and stated that it was not possible to draw any conclusions about size and race from the available literature and that further research needed to be conducted.[1]
According to Aaron Spitz, a urologist, many websites and studies promoting variation of penis size between races use unscientific methods of collecting information and often ignore contradictory evidence. He concludes that "when you really take a good look at the naked data, there’s not a whole lot there [showing racial variation in penis size]."[33]
In a small study conducted by University of Texas–Pan American and published in BMC Women's Health, 50 undergraduate women were surveyed by two popular male athletes on campus about their perceptions of sexual satisfaction and it was concluded that the width of a penis feels better than the length of a penis, when subjects are asked to choose between the two (size was left unspecified). It was also concluded that this may show that penis size overall affects sexual satisfaction since women chose between the two options they were given.[34]
In a cover story by Psychology Today,[35][36] 1,500 readers (about two-thirds women) were surveyed about male body image. Many of the women were not particularly concerned with penis size, and over 71% thought men overemphasized the importance of penis size and shape. Generally, the women polled cared more about width than men thought, and less about length than men thought, although the strength of caring for either among women showed a similar pattern.
Another study, conducted at Groningen University Hospital, asked 375 sexually active women (who had recently given birth) the importance of penis size the results of which showed that 21% of women felt length was important and 32% felt that girth was important.[37]
A study conducted at the Australian National University, published in early 2013, showed that penis size influences a man's sex appeal, and the taller the man, the bigger the effect.[38] The study showed 3D computer generated images at life-size, altering the height and other physical attributes, with women typically registering preferences in under 3 seconds. A preference for taller men's larger penis size was notable.
A U.S. study published in 2015 of the stated preferences of a panel of 75 women using 3D-printed models as scale references showed a preferred penis length of 16 cm (6.4 inches) and a preferred circumference of 12.2 cm for long-term sexual partners, with slightly larger preferred sizes of a length of 16.3 cm (6.3 inches) and circumference of 12.7 cm for one-time sexual encounters.[39]
One Australian study of 184 men looked at penis length and circumference in relationship to condom breakage or slippage. 3,658 condoms were used. The study found that when used correctly, condoms had a breakage rate of 1.34% and a slippage rate of 2.05%, for a total failure rate of 3.39%. Penile dimensions did not influence slippage, although penis circumference and broken condoms were strongly correlated, with larger sizes increasing the rate of breakage.[40]
Androgens like testosterone are responsible for penis enlargement and elongation during puberty.[41] Penis size is positively correlated with increasing testosterone levels during puberty.[42] But after puberty, administration of testosterone does not affect penis size, and androgen deficiency in adult men only results in a small decrease in size.[42] Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) are also involved in penis size, with deficiency (such as that observed in growth hormone deficiency or Laron syndrome) at critical developmental stages having the potential to result in micropenis.[43]
There are certain genes, like homeobox (Hox a and d) genes, which may have a role in regulating penis size. In humans, the AR gene, located on the X chromosome at Xq11-12, may affect penis size. The SRY gene located on the Y chromosome may have a role to play. Variance in size can often be attributed to de novo mutations. Deficiency of pituitary growth hormone or gonadotropins or mild degrees of androgen insensitivity can cause small penis size in males and can be addressed with growth hormone or testosterone treatment in early childhood.
An adult penis with an erect length of less than 7 cm or 2.76 inches but otherwise formed normally is referred to in a medical context as having the micropenis condition.[44] The condition affects 0.6% of men.[7] Some of the identifiable causes are deficiency of pituitary growth hormone or gonadotropins, mild degrees of androg
