Facts about the Average Penis Size

As of 2018, the average 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 13.11 cm 3.61 inches or 9.17 cm
Girth (circumference)
4.69 inches or 11.91 cm 3.67 inches or 9.32 cm

These measurements are according to a study done by BJUI (British Journal of Urology International).

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” (34.29 cm) long, and it is Jonah Falcon who holds that record. In its flaccid state, it is 8” (20.32 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.

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.

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

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.

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

Or if men always wore cycling shorts (“My eyes are up here, babe” ) :-p

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 90% of women prefer penis with a larger girth than having a longer one.

However, 68% 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.

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


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 2006 study, there is no connection to one’s physique and penis size.

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

  1. 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.

  2. 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.

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

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

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

  6. 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??

  7. 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.

    1. 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.

  8. What are you using to measure girth?

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

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

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

  10. 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.

  11. 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.

  12. 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.

    1. 8 centimeters is smaller than average. I would suggest you get a pump and do jelqing to get quick results.

  13. 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.

    1. 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.

  14. 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.

  15. 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?

    1. 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.

      1. 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.

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

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

      1. 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.

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

    1. 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.

  18. 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.

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

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

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

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

    1. Are you Asian?

  22. 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.

    1. Porn is 100% representative of average…

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

      1. Sounds like we got some salty koreans loooool.

    3. Liar!!!

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

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

  24. 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

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

  25. 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!!!

    1. 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…

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

      2. 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.

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