Facts about the Average Penis Size

As of 2019, the average human penis size is 5.16 inches.

Here is a more detailed breakdown of the average length and girth (circumference), worldwide, of an erect and flaccid penis shown in the table below:

Erect (hard) penis
Flaccid (soft) penis
Length 5.16 inches or 13.1 cm 3.61 inches or 9.2 cm
Girth (circumference)
4.69 inches or 11.9 cm 3.67 inches or 9.3 cm

These measurements are according to a study done by BJUI (British Journal of Urology International) and several other studies.[1][2]

Currently, the countries with the largest average penis size, 7.1”, are Congo and Sudan.

The country with the smallest average size, 3.7”, is South Korea.

The United States (and other Caucasian-population countries), on the other hand, have a modest average, which is around 5.1”.

Surprisingly, despite the typical racial slurs, the Japanese has a greater stat compared to Americans: 5.2” average.

The largest and longest erect human penis is 13.5” (34.3 cm) long, and it is Jonah Falcon who holds that record. In its flaccid state, it is 8” (20.3 cm.) long. His penis was so long that the TSA (Transportation Security Administration) has mistaken it for a bomb. If you want to visualize how long it is, imagine three iPhone 4s stacked upright.[3]

How to Measure a Penis Properly

Read our complete guide on how to measure your penis.

There are two ways to measure a penis:

  1. The first method is by measuring while it is erect.
  2. The second method is by stretching a flaccid penis and then measuring it.

The results of both approaches may have a few millimeters difference – but the erect measurement will generally be larger.

The most common method is the BPEL (Bone-Pressed Erect Length) measurement – read more here.

To know the length of a penis, get a ruler. Then, place one end of the ruler on your pelvic bone area — it is the hard and somewhat bony area above your penis. Be sure to put some pressure on the ruler until you feel your pelvic bone: This is to make sure that your pubic hair and layer of fat will not mess around with the measurement. Measure from the pelvic bone to the tip of your penis.

To get the girth, you can use a tape measure. Wrap the tape measure around the thickest part of your penis; it can be the shaft, base, or tip.

If you do not have a tape measure but you have a ruler, what you can do is get a strip of paper. Use that paper as a tape measure and check your penis’ girth. Mark the part of the paper that overlapped, and then measure the strip using the ruler.

Recommended tools: Girth Measurement Tape (amazon.com).

If penis sizes were as clear as bra sizes, the dating world would be very different.

Does Size Matter?

Fortunately, for those who are within or a bit below their national averages, there is no need to worry.

According to a research review journal from BJUI, women are more focused on a man’s looks and personality: penis size is not a priority.

Many men whose penis size is 5 inches or less begin to doubt their size. This is common but can lead to self-esteem issues and a feeling of insecurity. 5 inches is definitely average and nothing to be ashamed of.

Pumps and Extenders

Penis pumps and extenders are commonly used to increase the penis size. It is ideal to use both concurrently, along with manual penile exercises. They can work wonders if used correctly over a long period of time.

Length vs. Girth Gains

If ever you want to make your partner more satisfied with your penis, it is recommended that you focus on improving girth rather than length. According to two studies, almost 80% of women prefer penis with a larger girth than having a longer one.[4][5]

However, 67% of women who are with men with penis sizes below the global and national average wish that their partners have larger penises, according to a graduate study from UCLA (University of California, Los Angeles) Department of Psychology.[6][7]

On the flip side, most of the female respondents in the study (85%) said that they were satisfied with their partner’s penis size.

women's preference for penis sizes chart

In the same study, men were asked to rate their penis size:

  • More than half of the respondents (66%) rated their penises as average.
  • A few (22%) rated their penises as large, with the remaining rating their penises as small.

Those who rated their penises as large tend to rate their appearance higher compared to other respondents, which might imply that penis size affects a man’s confidence in his looks.

Watch girls’ reactions when they see a huge penis outline in tight shorts:

Different Studies Tend to Have Different Results

In the previous section, it seems that BJUI studies implied that most women are not that worried about their partners’ penile size. However, many studies and polls have generated a different conclusion.

For example, according to a Mister Poll survey, 81% of more than a thousand female respondents would turn down a very attractive male with a small penis for an average-looking man with a bigger package.

In the same poll, 75% of the respondents believe that penis girth and length matter a lot. Also, 61% of them have confided that they have dumped or refused intercourse with males with penis sizes below their expectations.

The poll also had male respondents (also more than a thousand), and they were asked how they felt after reading the women’s responses regarding penis size. Here is the breakdown of that poll:

  • 44% are confident that their penis is good enough.
  • 19% are overly confident that their penis can satisfy most women.
  • 17% are not confident about their penis size.
  • 9% are not confident about their penis size, but they are confident that they can still satisfy women.
  • 8% are extremely confident with their penis size and performance.

Accuracy of Studies and Measurements

Despite being heavily studied, there is still a huge margin of error when measuring penis size, especially if the collection of data relies on letting the respondents perform the measurement.

Also, multiple factors can affect a penis’ erection: ambient temperature, mood, age, and self-esteem.

Correlation of Penis Size to Body Parts

It has been a common saying that you can predict a man’s penis length by just looking at his feet, ear, height, and even the nose.

However, according to a 2013 study, there is no connection to one’s physique and penis size.[8]

Nonetheless, a few other studies have noticed a pattern, correlation of buttocks size to penis size, but it is still inconclusive.

manuel beltran says June 21, 2022

So many lies about the size of a penis. But I am being truthful about the following:

1. I am now 70 years of age and I measure 9 inches on top from pubic bone to tip of penis (correct measuring).
2. My starting size was 7 inches when I began my natural growth exercises.
3. Do not believe the misconceptions that the penis cannot expand or grow without penile surgery.
4. I notice that most penis growth websites forget a vital part of penis growth and that is the testicles.
5. Specific massages release testosterone in the testicles and they help with developing strong erections (even at 70).

ipickf says January 8, 2022

To be honest, I’m probably a bit above average, but everything depends on the woman’s vagina size.

Ponto says August 8, 2021

Well earl, you don’t you try and see for yourself. The main thing is to get your penis erect and to use it regularly as that is what keeps your penis healthy and functioning. Not much point having a whopper you cannot use.

Listen friends, the role of the foreskin in sexual intercourse is all in your mind. And any man who does not use some kind of lubricant on their penis for sex is a moron whether you are hooded or have a one eyed turtle neck. You do know that the natural penile lubricant on uncut men is actually smegma.

Brosmww says June 8, 2021

Mine’s girth is like one finger i think 3″ and lenght 4″ it is very thin but the glans are huge . The head girth is 6,5″ and head lenght is 2″ so half of it all. It has that mushroom shape but like a tiny small with an way big cap. It’s that normal ? Does anybody has this too ?

earl says September 23, 2020

I’m 68 years old – is that too old to grow an extra inch? I am 5 3/4″ long and 5″ around.

    Roger says September 11, 2021

    Earl, I’ll trade. Having 8.1” is a pain for the woman and not all that great for the man.

      cameron says July 26, 2022

      my girth is more than that, they don’t even make custom condoms that big

      Shaunda says August 4, 2022

      @Roger – I can’t possibly believe that’s true! I’m a woman. I’ve been with a man with an average length just shy of 6 in & a man with a length of about 9 in. I much preferred the 9 in. No discomfort at all. In my personal experience, the longer penis length allows for more variation of sexual positions. Allows for more exploratory positioning, also allows for a more lengthened withdrawal and thrusting, which is hot af. I will also say that one factor not mentioned is penile girth. I’ve had an average penile length with above average girth, and above average penile length with average girth. The above average girth does exponentially increase satisfaction in terms of that ‘fullness’ factor that aids climaxing.

      Have you had found having an 8 in penis has made sex difficult with more than one women, or has it just been your experience with one woman? I ask because maybe the problem is not your above average penis length, but with the woman herself? Conditions such as endometriosis can make sex painful for the woman, irrespective of the men’s penile length.

        Robert says August 31, 2022

        Yea that’s really true. And different women get off differently. I don’t know exactly how big mine is, I know its above average length, probably 6-7″ erect, but have a very large head. I just measured its 5.5″ soft. My advantage for answering this is that i’ve been with a lot of women, so for probably 90/100 its fine, no problems. occasionally if you’re with someone who’s used to a very large one you can tell they want more than you have even if they won’t say so. And for me my girth, occasionally maybe 3-5 out of 100 won’t let me put it in, and anal, nobody wants it from me cause the heads too big. Then for some they absolutely love it like its the perfect size. so like any other attribute, just remember there are billions of women out there and if the sex is bad and you can’t work it out, just find another partner.

LOL says May 27, 2020

Your chart for women’s pleasure preference has been modified to reflect smaller penises being ideal from the one that is available on many other sites. Losers.

    dumbass says September 17, 2020

    You’re retarded. The chart of women preferences that you see on other sites is complete bullshit for so many obvious reasons. And then there’s the part where 11×7 is somehow still called enjoyable. The vast majority of women find that painful. Yes there’s such a thing as too big. On top of that, according to a study conducted in 2015, the preferred penis size by women is 6.4×5.0. If you look at the other chart, 6.4×5.0 barely hits enjoyable. This chart is more inline with the data from that study. How you could be so stupid is amazing to me.

    Roger says September 11, 2021

    I’m a scientist and always check the original. The graph is the accurate one. Someone altered it for unknown reasons. Websites for women such as Cosmopolitan and HuffPost ran the altered one. Only one out of a hundred men have 8+ inches length or a girth of 6+ inches. I’m stuck with both and would never make fun of the smaller 6 inch guys with 5 inch girth. They’ve got the better deal. I’m 68 and when a teenager it hurt something awful to put a condom over a 6.5 inch girth. Big guys received much less sex.

lolustupidFa says August 7, 2019

Jonah Falcon was exposed as the lying, weird-faced liar he is…. years ago.

mrNedu says August 3, 2019

My erect penis is 7.4 inches in length and 5.2 inches in girth, but my ex said it was small. A lady once said it was perfect. I want to know if it’s big enough.

    Anonymous says November 22, 2020

    if she farts shes a hoe

Pussyman76 says February 22, 2019

7” x 5.5” nice straight penis, a bit thicker at the base.
I can hit the cervix by all women I have had. After pregnancies women enjoy this. Before, it is really sensitive.
Would like an extra inch on x and y axle, but when I tell my girlfriend she says I am totally mad and will send me to a shrink.
Most important is that it is functional and you know what to do with it.
If you have a big dick, she might not enjoy it because there is a-hole attached to it.
Woman enjoy sex and get orgasms (most do not by penetration) because they trust you, not because someone sticks a huge salami in their vagina.

    lol says July 8, 2021

    yes; brag about your size then say it don’t matter.

Fred Rhodes says October 31, 2018

Vaginas prefer whole, fully functional, hygienic, smooth, moist, sensitive glans penises for maximum sexual pleasure. Rough, dry out, permanently exposed desensitized glans penises cause excessive vaginal friction and erosion leading to increased dyspareunia.

Don’t allow people to circumcise your children’s neurologically and physiologically functional exterior reproductive organ parts, teach your sons to practice good hygiene and respect for women instead. Then women will not want to practice brain traumatizing medicalized religious infant genital cutting organ theft rites on your sons as part of their feminine hygiene rituals.

Marshall says July 30, 2018

I can’t believe this, I’m 9 inches +or- long depending on erection and 8 inches +or- depending girth. Yes measured by the rules by myself, then by my girl.

My mom used to embarrass me – she would ask my girlfriends “if I still have a huge penis”. She would tell them that when I was a baby, it was huge. That the doctor told her “he should grow into it and it should be average when he grows up”.

I have yet to be with a girl that hasn’t commented on it and have been told more than once that my girth was too much. I had problems when I was a kid. Being young I was too eager to get in there.

Then when I was 16, we got new neighbors. The husband worked out of town, and the wife was in her early 30s. She taught me to enjoy the foreplay and most importantly how to eat pussy. I have had no complaints or problems since. I have heard that most guys with big penises don’t know what they’re doing and that I act like a small guy. I owe it all to Jamie, wonder what she looks like now.

John says July 13, 2018

My penis is 15 cm but girth is only 11cm, is this normal?

Alex says July 13, 2018

I’m 16 and I’m 6.1” by 6” – is that good?

    Pp man says August 15, 2020

    Bruh I am literally the same and every girl has said its good, so yeee…

    Jethroskull says October 4, 2020


    Holmes says April 16, 2021

    I am 7.75 by 6.5 and it’s a touch too big. This means no anal ever and when hitting doggy style I have to stop short so no banging otherwise they get hurt 😞. Even missionary style I would hit the Cervix which is painful for most woman.
    Most importantly is how you work it. Don’t put your whole Johnson in until she’s about to pop. Tease her by no putting it in all the way and, right when she’s ready to pop, put that last inch or two in and feel the 💦 start gushing.
    Yours is probably the perfect size. But I wouldn’t trade with anyone.

Peter Kanonakis says July 13, 2018

Does a man’s neck length correlate to his penis length? I mean: will a man with a longer neck have a larger penis?

John Burke says July 10, 2018

My penis is 6.5 inch length & 5.6 in width… My fiancee is late on her period by a month. We have done 4 pregnancy tests and all came back negative… She keeps telling me it hurts with intercourse have I damaged her Vagina??

FromAPointOfView says July 1, 2018

I’m 18 years old and my penis size is 5.5 inches in length & 4.5 inches in girth and I can last about 20 or more minutes before cumming. Is that good enough to satisfy a girl.

    Vander says July 9, 2018

    You have a good size penis, and are above average in length and high average in girth. I think that lasting over 20 minutes definitely outweighs size. I have been married for 11 years and what I can confirm is that my wife prefers stamina and not so much my size.

John Wick says June 12, 2018

What are you using to measure girth?

    Lucas Owenby says June 13, 2018

    You can use a piece of string, as we mentioned in our measurement guide.

Vesper says June 9, 2018

My penis flaccid size is just about 1 inch, but when erected around 5 inches. Is this normal?

    Lucas Owenby says June 9, 2018

    Yes, this is perfectly normal. Some men are better hung than others. This also depends on the temperature in the room.

Nips says June 7, 2018

I find it funny the average size of a penis is 5.6 in, but the average depth of a p*ssy is 3.7 in, but somehow girls still prefer something bigger.

Somejoeslightlyaboveaverage says June 5, 2018

It’s all relative though because vaginas vary also. There’s no tight or loose pussy just like there’s no small pecker or big cock; there’s only partner comparability. Except in South Korea, I guess. Hahaha.

Tamal Roy says June 1, 2018

My penis size 8cm when it’s hard and ready for secretion. Is it the right size to satisfy my girlfriend? If not then kindly tell how to increase size and diameter because 3 months later we get married, please.

    Lucas Owenby says June 3, 2018

    8 centimeters is smaller than average. I would suggest you get a pump and do jelqing to get quick results.

Johnson3 says May 27, 2018

That is a bs average for Ireland. It’s not true, average in Ireland is 5.5 inches, so I don’t know why you included this nonsense. Where is your source? Who clinically measured a sample group of people from Ireland? Exactly! This is false and should not be published.

    Lucas Owenby says May 27, 2018

    With this type of topic – it is difficult to get accurate information. Firstly, average penis size is not important for any health prevention methods. Secondly, conducting such study is difficult since volunteers often lie about their size and see this study as a joke.

John says May 24, 2018

I’m 15 and my penis size is 6.7in, and 4.6 inches in girth when erect…. when flaccid it’s 4.5in, and 4 inches in girth.

Dude says May 10, 2018

I’m 6.5×5.5 which is apparently a healthy size but why does the chart show that the ideal size is about 7.5×6.5? Most men don’t have that. That should be easy enough to achieve within a year of exercises. Does that seem correct?

    Lucas Owenby says May 10, 2018

    The “Women’s Preference Chart” shows the ‘ideal’ size. Not the most common, most healthy, or the average. Also note that every woman is different – so it is impossible to create a universal chart with ideal sizes.

    And yes – with pumping and exercises, your first inch of gains should be the easiest. You could achieve that within a few months.

      dave says June 26, 2018

      That woman’s preference chart is aloud of rubbish. Women do not actively measure their sexual partners’ penises and would be based purely on estimations and their perception which is completely different from a man’s point of view. When women are looking at his penis, they would almost definitely overestimate from their perspective, i.e., the angle they see it from or to be cruder when it’s pounding their 3 and a half inch deep vagina or hitting the back of their throat.

      Basically, that graph is absolutely bogus and has no scientific or factual standing. The only thing that its good for is making a large number of men feel more inadequate and insecure. Wish people would think before spreading misinformation.

Pnkj says March 15, 2018

My penis is 4’5 inch 4’2 girth – will it affect my sex life?

    Lucas Owenby says April 7, 2018

    Pnkj maybe your wife will be looking for the next door neighbors to get herself satisfied hahaha haha

      Vander says July 9, 2018

      You are very immature, if you have nothing constructive and intelligent to contribute, just keep your comments to yourself. This is not some sleazy chat site you simpleton.

      Hey Lucas, looks like you’re the dick, a big one.

Ranjan says March 10, 2018

My penis size 5.1″ and girth is 5.5″ erect, is it normal?

    spike says April 1, 2018

    According to Telegraph newspaper, the average dick Size is 143 cm3. You have 201 cm3 – that’s 40 percent bigger than average. My guess is that you are somewhere around the top 20-25 percent of all dicks in the world on a normal volume curve.

spike says March 3, 2018

The coloured map only shows length. 70 percent of size is girth. So the examination itself might be correct, but the map is displayed wrong. The length in the graphs is 2 cm longer than the actual visible length because they measure pressed to the bone. 6.5 is 5.7 or so.

    ya wank says March 7, 2018

    That is not true. If my penis was 8 inches long and 1 inch wide, 70% is not girth, is it?

Zack says February 23, 2018

My penis is 3 fingers wide. Is that too much?

mikespike says February 23, 2018

Interesting chart on length, but really says nothing about Size ( volume ).

Zack says February 22, 2018

I have a 6 inch penis I am 14. Is that normal?

    Helena says May 18, 2018

    Are you Asian?

hieric says February 12, 2018

I don’t think South Korea’s penis size is the smallest… I’ve heard and found out in multiple pieces of research that South Koreans have an average size of 13.22 cm… How could they have 9 cm penis???? That’s very funny. They have smaller penis compared to Japan?? I did not know. When I watched multiple Japanese porn, they usually had much smaller penises than South Koreans.

    Johnson says February 16, 2018

    Porn is 100% representative of average…

    Flo says April 18, 2018

    Yea, apparently in the Korean study they reported the flaccid length as the erect length.

      JLOEB says May 17, 2018

      Sounds like we got some salty koreans loooool.

    john says June 29, 2018


    Korea is a country that prohibits porn movies. Korean porn movies do not exist.

Taariq says December 30, 2017

I am 14 and I have a 16.5 cm length and 13 cm girth penis. Is it normal?

    rao says June 5, 2021

    You are a good liar! Because if you possess 6.5″ phallus, then your girth should be at 5.5 and greater… and moreover you are at 14 years…

Jewelz says November 20, 2017

It looks like you have the average girth of an erect penis (4.69 in.), as being smaller than that of the average flaccid girth at (4.96 in.). I highly doubt that given the amount of accuracy to the study as a whole, that this was simply a typographical mistake, however, I do find myself wondering why there is absolutely no mention of this fact whatsoever, anywhere within the entire study and its conclusion. It just seems to me that with such a high emphasis in regards to girth, the fact that the worldwide average girth of an erect penis being somehow smaller than that of the flaccid girth, would at least be worth mentioning. Or maybe it was just a typo…either way, just wanted to “throw that out there.” XD

    Lucas Owenby says November 20, 2017

    Indeed it was a typo. Thanks for pointing it out. We fixed it according to the study.

Brian says November 20, 2017

I don’t really get bothered about what women think because if they want bigger, then it’s because they have an extremely deep and stretched vagina.

But I did wonder because when they say they have had 9 to 11 inches, it gets you thinking “are you big enough”. But then they will say it hurt, and they sucked in bed, didn’t know how to use it, so I don’t know.

I’m 7 1/2 when I’m totally at my best hard on. But now that I’m not turned on by this woman much anymore, I’m about 6 – I don’t understand how that is, but it is. But she still loves it and would actually want it smaller if she could choose.

How can I get girth naturally and keep it? I also wonder and compare my size to my girl’s past guys. I would like to just see them in person or picture, I’m not gay, but I just wonder if they really tell the truth. Or do they just tell you what you want to hear to make you feel better and more confident and not to ask again!!

I’ve only heard I was small by 2 women and they were girls that were with guys that were bigger for a long time. But they say that they never got off (or very rarely). And when they did it wasn’t great. I always hear that I’m the only one to get them off and it is great orgasms. So idk, I just would like feedback from some women or someone that knows about this more than myself!!!

    Kelli says December 17, 2017

    So are you saying you’re not turned on by your girl anymore, so you’re now a 6 in size? So it shrunken? I know if a guy gains weight his penis gets smaller, but when he loses weight, it gets bigger…

      Johnson says February 16, 2018

      It doesn’t actually get smaller/bigger. The pubic fat-pad grows/shrinks.

      Kelli, do your research first. It does not get smaller due to weight gain. It just looks smaller because there is more fatty tissue build up in the pubic bone area.

    Yes I do agree. I feel the same … can any women tell the truth?
