Despite the fact that most women will say that the size of a man’s erection is not important, men tend to focus on the measurement, believing it to be a sign of manliness. In fact, one of the most common questions asked on internet question and answer sites is regarding penis size, with men wanting to know if they are “average.”

Average Penis Size

An erection that is three to four inches falls below what many reports say is the average erection size. There are several estimates for the average size, ranging from 5.1 inches to 6.4 inches. According to the Kinsey report, one in 100 men measures between five and 7 inches, while only seven in 1,000 men is larger than eight inches. However, a Lifestyle condom survey, which had nurses measure the erect penis of 300 men found that the average erect penis size was 5.8 inches, much lower than the Kinsey report survey. The difference was that the Kinsey report survey accepted the men’s own measurements rather than having an impartial party measure.

Common Household Objects

Common household objects that are between three and four inches include:

• A business sized envelope is 4 inches wide
• The average store receipt is 3 inches wide
• A deck of playing cards is 3-1/2 inches tall
• One slice of processed sandwich cheese is 3-1/2 inches across

Research indicates that men are often wrong about penis size, with most of them underestimating the length, both erect and flaccid. Some researchers say that the angle that a man looks down at his penis makes it appear smaller than it actually is, and it is more than likely that his penis size is average or above average.
