Penis Size Comparison With Facts and Measurements (Infographic Presentation)

There’s no beating around the bush here, folks — there are just some things in life that are better when they’re bigger: bank funds, flatscreens and wine tumblers, just to name a few.

However, is “BIGGER” necessarily “BETTER” when we digress from mega fishbowls at Happy Hour, and analyze the size discrepancies of certain body parts?

No, fellas — this isn’t a discussion about the female form, but rather one of Freud’s favorite topics: the PHALLUS or PENIS.

Penis Size Comparison Smallest To Biggest Plus Facts

Measuring Members

The most accurate measurements of the penis fluctuates by size variability and primate species. Phallic-size fluctuation is dependent on a number of factors, including arousal level (such as time of day); room temperature; frequency of sexual activity, and reliability of measurement.

What are the differences between primates?

For starters, most primates have a penis bone and can achieve erections via muscle contraction. In contrast, the human penis has evolved the vasocongestion system to achieve erection, making the erect organ more flexible than other primate species.

In terms of size, the average erect gorilla penis is 3cm(1.25 inches) long, versus the average chimp penis that ranks in at 8 cm (3.15 inches) long. Compared to other primates, the human penis is the largest (in both absolute terms and relative size to the rest of the body) — but don’t get too cocky just yet, fellas!

Even though men sport larger members than their tree-swinging ancestors, the average erect penis is no more than 5 inches long and inches in diameter. Additionally, just 15% of men exceed 7 or more inches, and only 3% of men are over 8 inches — or, the average length of a banana.

The smallest recorded human penis was 5/8 of an inch, while the largest recorded human penis was 13.5 inches. Penis size is not considered a medical concern, unless the penis is shorter than inches when flaccid and/or 3 inches when erect (you can breathe easy, gentlemen).

Fascinating Phallic Facts

Did you know the best way to increase penis size is by losing belly fat? For some men, this should be plenty of incentive to hit the gym more often!

Another penis health incentive to consider? Stop smoking to prevent shrinkage! Research has shown that the effects of long-term smoking impacts penis size; shortening a man’s erection length by reducing blood flow throughout the body, and also to the erection. On average, smoking has been known to reduce an erection by up to half an inch! Nicotine patch, anyone?

Additionally, the “big hands, big (___)” myth has officially been dispelled, so all you “SIZE 5″ sneakerheads out there are in the clear! Scientists have long-attempted to connect penis size to the size of mens’ feet, noses, thumbs, earlobes and index fingers; even going so far as to try and bridge a connection between flat buttocks and long penises. The (not-so-surprising) verdict? The fact, there is no real way to predict penis size, without actually looking at the penis.

In terms of national size discrepancies, two countries sport very contrasting measurements! Congo reigns in as the big daddy of endowment; sporting an average penis size of 7.06 inches when erect, versus North Korea’s unimpressive, 3.8 inches (dare we say: Napoleon complex?)

Jonah Falcon of New York is considered to have one of the largest penises in the world! Believe it or not, TSA airport security had once mistaken Falcon’s penis for a concealed weapon (insert “Naked Gun” joke here). Jonah Falcon measures in at 9.5 inches (24 cm) in length when flaccid, and a lengthy 13.5 inches (34 cm) when erect. Some guys have all the luck.

Comments and Insights

  1. Aloon195 says

    My penis size when full erection can reach up to 8 inches … I am 15 years of age, and im 6 feet 3inches … If this will continue to grow, I can match that record :D

  2. Carlos says

    Pardon my ignorance(no pun intended)… What causes the many differences in penis size in human male? I mean we see Jonah who has 13 inches while others have only an inch or two…

  3. Pete says

    Mine is not even half of Jonah’s :D But penis enlargement does helped me in someway. My penis size was originally at 4.5 fully erect…after 1 year and 6 months of doing penis enlargement with mixed Jelqing and using my sizegenetics ultimate package, I’m not at 5.3 inches(almost 5.5)… I know I can’t beat his record, but I’m happy with what I’ve achieved.

  4. Mateus says

    Is there a penis size chart for teens so they understand how huge their penis is compared to other ages as well as those with similar ages? A graph or chart would be helpful.

  5. Louella says

    When people say the average size of a men penis is between 4-5 inches is that talking about the size while fully erect or is it the size when not erect?

  6. Howered says

    Ok, just for fun whether someone is interested on this…I wonder to what causes distinctions in penis size. Just would like to know where I got mine from. :D

  7. Brainitterem8958 says

    I see this all the time. People asking if their penis size is good or bad. As a matter of fact, I see a lot of those who asked such questions provide measurements in inches!

    Personally, I have never measured my penis ever since. And, well this is just my personal opinion, it seems like crazy for me to actually measure the penis and for those who are doing it. Some even have to measure several times a month, I’ve read it many times. If you look at your penis, you already know whether the size is acceptable or not. I don’t find it necessary to have a ruler and begin measuring the penis.

    Very nice infographic. I didn’t realized there was such a small penis, it can truly be considered a micro size. :D Well, I guess that’s life. If I was that guy, I would present myself in clinical studies(if there are any) on penis extenders or other means of increasing the size of the penis. But, I guess there are not many studies as such these days.

    What I’ve found recently is a survey on average penis size of Americans. I guess researchers have been exhausted of ideas about increasing penis size. Hopefully, there would be a clinical study that is approved and validated by health authority regarding these new breed of penis pumps. Although, a lot of these pumps provides great results for many individuals, there haven’t any actual clinical studies done just as they did with traction extenders.

    Having such studies will allow more men to be comfortable with these types of pumps. On the other hand, downside would be imitation might popup everywhere just as what happened with Bathmate :)

    Well, just IMHO :) Great job on the graphic, btw!!!!

    • Michael Wiener says

      Thanks and I’m glad you liked it! :)

      Btw, you seem very familiar with these things, are involved in some sort of penis enlargement endeavors?

      • Lance says

        Hi Michael, thanks for the reply.

        Not yet! :) But, I’m looking into it. In fact, I’m reading your Penomet pump review and it catches my interest.

  9. Arnie says

    I thought that penis with such size only exist in porn through some form of special effects. This is my very first time to have a glimpse of this very interesting fact. How did that happen to him? He look very normal. Wow! I can’t imagine those men walking across the street. I wish I have an x-ray eyes to see different size… well, just for fun :D

    • Keith D. says

      If I can recall correctly, there was a camera manufactured with such capability but was recalled… I mean dropped of production. Forget the brand, and I’m not sure if it was really true and existed.

  10. Brad says

    I like the way the information presented. It’s kinda funny, controversy, and factual at the same time. Great job!

  11. Anthony says

    Really! 13+ inches? That’s the length we’re talking here, right? But what about the girth? Man! He should be a porn star, or he is already!?

    • Michael Wiener says

      Jonah Falcon measures;

      8 to 9 inches flaccid
      13.5 inches erect
      6.5 inches girth

      And, No. I think he is not in porn, which is very surprising. I’ve read somewhere he is an editor of a gaming blog, and he is an actor according to his biography at IMDb.

  12. Mark S. says

    Very nice infographic. First impression, I thought there was something like a video showing the comparison of sizes :)

    I’ve heard that Jonah Falcon incident. I thought it was hilarious and was a joke, but it was not. Perhaps Guiness would find a world record holder. I’m sure there is someone like Jonah out there. Let them do the research :D

  13. Andrew says

    Very interesting facts presented in this infographic. I never thought there is such that small human penis existed. Since the day I was curious about my penis, I thought that 1+ inch penis long only exist in kids :)

    Btw, great infographic!
