Penis size is a great concern for a lot of people, every man has wondered if his size is normal or not. Porn, myths and exaggeration (specially on the net) are making people less confident about the sizes of their penises, and true information is not that easy to find on on line. This section has the aim to show some serious studies on the issue, most of them carries out by professionals, and give a realistic idea about what is Average and therefore normal.

For more information about scientific studies about penis size visit penissizestudies, where detailed information is provided for most of the studies published to date..

First we start with this table in which 21 flaccid penis size studies are shown:

Note that the first two as well has the study carried by Dr Acuña refer to self reported measures, while the rest are measured by professionals.

As a first approximation we can see from these studies that the average penis size in flaccid state is 9.1cm (3.6′) long and 9.6cm (3.8′) thick (circumference at the thickest point), but due to the great disparity of the averages [7.76-11.76] it would be more realistic to say that average flaccid penis size is somewhere between 8.5 and 9.5 centimiters (3.3-3.75 inches) and between 9 and 10 cm (3.5-3.9 inches).

This chart shows studies on erect penis size:

It is even more evident here how self reported surveys give statistically larger averages that those studies done by professionals. The average shown in yellow takes into account the size of the population studied, so these studies rise the average by being the biggest. That’s why we shouldn’t say anything else than the average erect penis size is somewhere between 14 and 15 cm long (5.5′ – 5.9′)  and between 11.5 and 12cm thick.

Summing up we can say that a real men penis size is difficult to find due to the variability of penis size and the lack of good and big studies.



  1. Cool so why have you set this site up, whats the aim?

    • I once wondered what was really the average penis size, so instead of just checking yahoo answers and as I had the means, I did some research, in the way I found the mesuret.org webpage and found it very illustrative as there’s a lot of confusion about the issue.

  2. I think your average and summary of the 5 sizes are correct. However the photos you use to depict the sizes are far from accurate. A lot of the 2s should be in the 3s, and a lot of the 3s should be in the 4s or even the 5s. Way off. I think mesuret also had the same issues. Really take a good look at what 3.5 inches is or even 4 flaccid. Some of the flaccid photos you have in the 3s are clearly 5 inches or more soft.

    • You were right some were in the wrong place, I’ve deleted a few of the 2s and the 3s, some of which were already in the 3s or 4s respectively. It is sometimes difficult to keep order to so many pictures.
      Probably I haven’t deleted as many as you mention in part because there isn’t a clear border between sizes, one might think it’s an upper limit 2 and another might think it’s a lower limit 3… I usually use the fingers as a reference: a thumb or less (to the joint) is clearly size 2 (or 1), more than a middle finger (to the knuckle) is very probably a size 4… Always more or less
      Thanks for submitting and for your thoughts about the averages and the 5 Sizes summary 🙂

  3. Just b ur sef

    I have had sexual intercourse with at least 15 unmarried and 4 married with my penis size of 5.3. suprisingly nobody among them ever complained about the size and they used to satisfy with it. why, were they pretending? Please comment, especially females.

    • Why would they pretend? Your size is pretty much average and in any case penis size is not the most important thing in sex by far.

      Any woman that you would actually want to have a relationship with doesn’t give a damn about penis size (within reason). If you fall into the micro-penis category, there is still a woman out there who will love you and won’t give a damn, but she may be harder to find. Most women actually want something in the middle (high 2 to mid 4). Here’s the thing. Everyone’s anatomy is different. My ex was a little longer (maybe a half/three quarters of an inch?) than my current BF. From behind my ex would bang into my cervix and it hurtling someone setting off an electrode k. The middle of your pelvis (I imagine it’s a little like getting kicked in the balls). My current? Not a problem. Bottom line. If she’s actually into you? She’s not going to care. Like everything else, being with a new person means learning what works for you and for them. It’s not going to be the same. All the tricks you use on one person may make another look at you like “huh?” If you’re anywhere from 4-7 inches? Stop sweating it. Put your best foot forward, focus on her, and she’ll be happy. (Unless she’s a shallow, vapid, bitch—In which case you’re better off running far, far, away.)

  5. Hello you have a great website over here! Thanks for sharing this interesting information for us! If you keep up this great work I’ll visit your weblog again. Thanks!

  6. Hey, just wanted to say that I’m extremely grateful for your work with this site. I have a pretty average size, yet have always had some anxiety about it, but your site is helping me deal with me insecurities a shit ton. Thanks!

    • Thanks for your words, this is precisely the aim of this website. To bring some information to a internet full of distortion which can create discomfort of anxiety.

  7. It’s not about the size but how u use it! U may have a size 5 but u perform like a dead slug… Might as well hit u on the head with it.

    Be confident with who u are and ur girl won’t dare say yours is tiny/adorable/cute.

    #from a female perspective#

    • You are right, size has a limitted impact on sexual pleasure. This site is About what you mention, beeing confident with who you are by showing normal bodies.

  8. gd job.U are worth the praises

  9. I submitted a picture. Is this site still active? How long until it is uploaded onto the site?

  10. i think the only reason why people complain about size is only visual attraction. Women usually don not have a a ruler to measure your penis, Where is not much difference between for example 14 and 16(but people are saying that 14 is small and 16 is average), especially then one man is short another is tall, first is thick second is fat.

  11. My photos still have not been posted to the site.

  12. how to measure the right way?

  13. Thank you very much for your website I actually found out thst I am above aversge size, I have multiple women I have intercourse with and never any complaints but like most women they say its not the size that matters but how you perform in bed!

  14. I use my navel as refference, so please tell me where each size is.

  15. I have a less than average penis size (2.00″ x3 3/4″) but i never had any trouble with the ladies,(1 or 2). Most women would rather a man be sensitive to their needs rather than slamming their heads against a headboard. At least that’s what I found over the years.

  16. This site has really boosted my ego. I am a large man 6′ and 375 lbs. Because my body is so large my penis always seemed small to average to me. I was embarrassed and ashamed for anyone to see it. However a few years ago I went to my urologist for ED symptoms. She gave me an Rx for a Pos-T-Vac vacuum erection devise. One size was supposed to fit all but my penis extended beyond the capacity of this devise. The Pos-T-Vac measures 8 inches or 20 cm. she had to special order me a custom 10 inch model. I am 20.955 cm erect which I understand to be in the top 2% of all men world wide. So my point is even really big guys often feel as though they are small. I always did. I am a grower and not a show’r. Hope this helps other guys out there.

  17. If I can figure out how to do so, I will upload some pictures to verify…

  18. So what are the extender things I been hearing about? I keep thinking my dick is average but I personally want it bigger. I been doing some of the exercises like jelqing or whatever and stretches..Mine is like the one where it said flaccid I wrap my fist around the shaft and there is a bit more and the head sticking out….I just can’t believe how the guys on here look small flaccid then they get erect and there a lot bigger!! I don’t think mine gets that much bigger when erect. My ex girlfriend was on a drinking binge and said the last guy she was with was like double the size of mine…which I don’t know if she was trying to hurt me or what, but I asked her how big she thought mine was and she said “maybe 5.5 or 6” which I thought was pretty decent myself. But after that I just want to be bigger. What are the best and quickest ways. BTW Cialis I’ve tried and they just make you really hard for like 4 hours LOL. But it does make the blood flow and makes you horny. I like them but only if you plan on fucking for like a few hours LOL.

    • 5.5/6” is completely average, so don’t worry about it. Also, if your exgf said her previous partner was twice that she was very probably wrong. 11/12” penises may exist (or even may not) but are extremely extremely rare in any case, and are more of a course than a blessing.

  19. Using the bone press method I am more than average. About 6.5 inches. For some reason it still feel like it belongs in the 2nd category? Maybe the way yours naturally points has to do with overall appreance. A long with how you were circumcised.

  20. i have dick which in 6 inch when erect and girth is only 4.8 inches is it normal? i m very worried i havent had sex ever because belong to muslim country and i m going to get married soon..can i upload picture here?

  21. For some reason recently I keep meeting men who have really small penises. I think women are also different and so they have different needs in terms of size. And this site focuses on length while from where I’m looking, girth is way more important. Not that length isn’t, but that can go both ways. Meaning it can also be too long.
    Speaking for myself only, I do not find overly small penises very satisfying. Nor the overly large ones, as I happened to have the luck of meeting a man with one once. Can we have a similar survey that includes girth too, maybe you’d need a two dimensional grid of sizes then.

  22. Size is a factor, of course, but so is the health of the organ, and men tend to neglect this. Regular use of a superior penis health crème can deliver amino acids and vitamins directly to the tool.

  23. It’s a good aproach in general, but it misses something. “Size” changes from flaccid to erect are not only possible in Size 1, there will be people in S2 flaccid that is S4 erect, people in S3 flaccid that almost won’t grow and is S2 when erect, etc. It would be more accurate to stablish two separate scales, one for flaccid and other for erect, as the correlation flaccid-erect is way less strong than suggested here, with a big % of exceptions.

  24. This has been an excellent website, and thank you for being clear minded about the information and the photos you’ve shared! One thing that’s become quite clear to me is just how much pornography has distorted men’s sexual self-image. Just for the record, and I don’t mean to “brag” by sharing this about myself with everyone reading this post, but I’m about 13.5cm flaccid and 21.5cm fully erect. For a long time, I used to think that I was “just average,” but now I realize that such is simply not the case. I sincerely hope that more websites like this become the norm so that all men may find sanity and healing along with a healthy dose of sexual balance in their lives.

  25. Is the penis is normal? if it’s smaller than normal when it is flaccid but normal in size when it’s erected.

  26. Your site is awesome! Thank you for taking the time and for putting forth the effort in creating this page. This page has given me a realistic approach to “size” that I did not have before stumbling upon this page. Thanks again!!

  27. There is a new study that was published at the start of the month which puts the average a lot lower than this web page. They use around 20 clinically measured studies. http://onlinelibrary.wiley.com/doi/10.1111/bju.13010/full Are you going to adjust you site for this new information?

    • Yes, when I have time. In any case most of the studies included in that metastudy are already included in the statistics of this page and even more in penissizestudies, ehich is more updated

  28. Going from the pictures you present, your categorization of penises is based on flaccid length. If thats true, it seems a bit pointless. Its erect size thats relevant. My penis would be classified Size 1 when flaccid, size 3 for erect length and size 5 for erect girth! Note that I get girth from a different site. Given that many women prefer girth over length, a listing of penis volume may provide a better comparison. I’d end up a size 4 in that case. A lot different to the shower room size 1. Make me want to walk around with an erection.

    • It’s not based on flaccid size. Sizes erect and flaccid can of course be diferent! As for girth, you are right, it might be even more important although it’s nit included here

      • But you put toguether flaccid and erect states into the same page, what leads the reader to think that there is a steong correlation between the two lenghts (“this penises usually are between X and Y when erect”), implying you can predict erect length from flaccid, when that only works for a % of the cases.

        This is supporting the stereotype of “bigger flaccid means bigger erect”.

    • The same happens to me to.

      I’m Size 1-2 when flaccid and size 4 when erect… it’s a bit weird because less informed people thinks I have a very small penis when erect I’m bigger than most of them.

      To be honest, I would change a bit of erect length for flaccid length just to be more confident when naked :/

  29. I found this site very informative! I have been married to my husband for 16 years, we were married at 19. I had other sexual partners but I was young and didn’t have a clue what I was doing and paid no attention to penis size. My husband has made a few remarks about his penis being “too small” and hoping it satisfies me. Although he is AMAZING in bed and brings me to orgasm during PIV sex 99% of the time I have often fantasized about a large penis. Looking at these pictures proves my husband isn’t small at all, he’s not a 5 but easily a 3. Average, I’d say. Thank you for the info, I have a new found appreciation for my hubby’s penis!!!

  30. There is no info about girth. My girth is 10cm flaccid and 13 cm erected. Also my penis size falls between type2 and type3-flaccid-8.5cm, erected-13cm.

  31. I have a size 4 flaccid and a size 1 when erect. Like, it just goes up, it doesn’t seem to grow. What does it mean?
    Unlike “Ringo” above, people often believe I have a larger penis when in reality its pretty small, I am 11cm both hard and flaccid.

  32. I’ve been married to a man with 4-1/2 inches when real hard . He had always said that was above average . After finding this site , I believe the size of my vibrator is closer to above average . But he does have a large head…I never realized how many different size penis there are out there ..Wow !!

  33. Mine is a size 3 when flaccid, so at nude beaches and in gym showers it all well and good, but when erect I am a size 1. It’s weird because everyone thinks I’m fairly well endowed, at 9cm flaccid, but I grow only a mm or so when erect, making me just in the top band of Size 1. Is it normal to only go “up not out”, because that’s what it does?

  34. I am very grateful too for this site. While I have seen many flacid penises in locker rooms, school, etc. I really only saw erect ones in porn. As you have mentioned these men are chosen for their large size. So, like so many men I thought I was very small. I am a “1” flacid but right in the middle with a “3” erect.I am more sensitive to cold, my hands and feet are often cold. I don’t know if that is why I am so small flacid.

    Thanks again for the measurements. When girls have said they don’t like small penises I always assumed they meant me. I often felt as I would disappoint a woman. This has given me so much more confidence and security. I still wonder why girls always talk about liking big ones. I know some men like big breasted women while that doesn’t mean anything to me. I suppose there are women who just need the visual of a big one? Are you still accepting photos?

  35. Are these sizes all Bone Pressed?

  36. Is flaccid measured bone pressed?

  37. My pennis size is 5.51 inch erect but only 4,25 inch girt, do you think is ood enough for a woman? My lenght is good but my girth looks like not.

  38. Nice sizes

  39. I’m curious as to what effect the size of a guy’s balls (both scrotum and testes) has on the perceived size. Are there similar studies out there on the topic?
