Average Penis Size

Fun Sex Fact — The average penis size is 5 to 6 inches long and about 4 inches around.



Human penis size refers to the length and width of human male genitalia. Compared to other primates, even larger primates such as the gorilla, the male human genitalia are remarkably large. The human penis is both longer and thicker than that of any other primate both in absolute terms and in relative size compared with the rest of the body. To get the most accurate measurements for an individual’s penis size, it has been recommended that several measurements be taken at different times, preferably with different erections on different days. Then average these figures together. This is to account for what may be natural variability in size due to factors such as arousal level, time of day, room temperature, frequency of sexual activity, and unreliability of the measurement methods.


While results vary across studies, the consensus is that the average human penis is approximately 5.1 – 5.9 in in length. The typical girth or circumference is approximately 4.85 in when fully erect.
