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”. And 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:
- The first method is by measuring while it is erect.
- 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 to 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.
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.
Penis pumps and extenders are commonly used to increase the penis size. They can work wonders if used correctly over a long period of time. Read our penis pump reviews (for Penomet and Bathmate) and extender reviews to see people’s results. You can also do jelqing or manual penis exercises at home right now.
If ever you want to make your partner more satisfied with your penis, it is recommended that you focus on improving its girth rather than its 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.
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 what and 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.
