What is the average size of a penis?
What is the average size of a penis? …the question so many men want a real answer to. There have been numerous charts, surveys and studies conducted regarding the average size of the human penis. The truth is, measuring a penis is no easy matter.
In his legendary studies, Alfred Kinsey measured 3,500 penises in the mid-1940s to determine what was indeed the average size of human penis. Every study I looked into basically listed the average penis as somewhere between 5.5 and 6.5 inches in length, with a girth between 3 and 4 inches in circumference.
Length of a penis is typically measured with the subject standing and the penis held parallel to the floor. Measurement of length goes horizontally along the top of the penis from the patient’s base to the tip. Girth is measured by using a tape measure.
Average penis erect size
The following information have been provided by the site that helped me the most, that is of course Penis-Health.com. At Penis-Health they also have large high quality pictures as well as videos tutorials on how to measure your penis. The erect length is what most men are interested in. It is best to measure from the side of the penis with the subject standing and the penis held parallel to the floor. Make sure you have a 100% erection and then hold your penis below the head and place the ruler next to it with your other hand. Measurement of length goes horizontally along the top of the penis from the base to the tip. This method is the standardized method that researchers use to measure the “average penis size” which is incidentally between 6″ - 6.5″ erect length.
Several studies have been performed to measure the average erection length.
Kinsey’s results have indicated that the average length of erected penis is 6.2 to 6.4 inches, with 23.9% of men falling into this category.
Another study conducted by Lifestyles Condom Co. in 2001 puts the average of a male sex organ at 5.877 inches, with about 2/3 ranging between 5.1 and 6.2 inches. They obtained this figure in Cancun during spring break, by letting a team measure the erections of hundreds of partying college students over 18 years old. 54% of subjects measured between 5.5 inches and 6.3 inches in erect length.
Average flaccid penis size
Now, let’s see about the average penis size not erected (soft). To measure accurately it is important that you measure from the side of the penis. Stand up straight and extend your flaccid penis in front of you without stretching it. Your penis should now be parallel with the floor. Place the ruler next to your penis so it is slightly pressing against the pubic bone. The ruler and your penis should be parallel with each other.
Many studies concluded that mean flaccid length was 8.8 cm (3.5 in).
Average penis size girth
Penis circumference is defined as the linear distance around the widest part of the erect penis. To measure the circumference of the penis, otherwise referred to as girth, make sure your penis is 100% erect and then proceed with the measuring. Hold your penis out in front of you so it is parallel with the floor. With your other hand place the tape measure around the penis making sure not to pull too tight. You can also use a string and then measure it with a ruler. The average erect girth is 5″ - 5.5″ according to recent surveys conducted.
Kinsey’s girth measurement average was 4.75 inches, with the majority of men clustered around 4.5 to 5 inches in circumference. All girth measurements were taken from around the middle of the penis.
According to the Lifestyles Condom Co. study, the average erect penis had a girth of 4.972 inches. About 75 percent of men were between 4.5 and 5.5 inches and 17 percent of erections measured under 4.5 inches.
Average penis size by age
These values represent the average erection length in each age group according to several studies and surveys.
The size of the penis changes during puberty. Penis grows in length first and girth slightly later and starts between the ages of about 10 to 14 years of age. Average teenage penis sizes and mature erected adults:
| Age | Average Penile Length (in inches) |
| 10 | 2.5 |
| 11 | 2.6 |
| 12 | 4.1 |
| 13 | 5.1 |
| 14 | 5.7 |
| 15 | 5.9 |
| 16 | 6.2 |
| 17 | 6.2 |
| 18 | 6.3 |
| 20’s | 6.3 |
| 30’s | 6.5 |
| 40’s | 6.4 |
| 50’s | 6.3 |
Average penis size by race
So, do black males have larger penises than average? Do Asians have smaller penises than average?
One study by a Canadian psychologist states that “penis size also varies moderately across populations, being largest among African populations, smaller among European populations, and smallest among East Asian populations”. Another study based on specifications for Condoms, indicate that black men on average have a slightly wider and longer penis size, white men have a medium size, and asian men a slightly narrower and shorter size. In a British study examining condom use, 18% of people of African descent, 7% of Caucasians and no Asians reported frequent breakage. A relatively higher incidence of micropenis has also been found in several Asian populations, including Chinese, Japanese and Vietnamese samples.
| Whites | 5.5 to 6 inches in length and 1.5 inches in girth |
| Blacks | 6.25 to 8 inches in length and 2 inches in girth |
| Asians | 4 to 5.5 inches in length and 1.25 inches in girth |
Conclusion
The most likely average penis sizes:
The average length of an erect penis is about 6 inches (15,24 cm).
The average girth of an erect penis is about 5 inches (12,7 cm).
The average length of a flaccid penis is 3.3 inches (8,38 cm)
