The composition of the average human man can be broken down into a series of specific physical measurements and statistics—some of which might surprise you. For example, an average man's head is about 7 percent of his body weight. That means the average man with a weight of 172 pounds has a head that weighs more than 12 pounds!

By identifying these standard stats and measures, some health issues can be more easily identified when a specific measure skews outside of these averages; however, also being averages, variations do not necessarily mean there is a health issue.

Average Height

5 feet, 9 inches (1.77 meters)

Average Weight

172 lbs. (78 kilograms)

Average Weight Distribution by Tissue Type

Average Body Weight Distribution

Average Area of Skin

If laid flat, the average man's skin would cover between 36 to 59 feet (11 to 18 meters)!

Average Lifetime Heart Beats

2,700,000,000 beats over an average lifetime, at a rate of 72 to 80 beats per minute.

Total Number of Bones

206

Average Number of Sperm Produced

The average man can produce 3,000 sperm a second.

Average Number of Sperm Per Ejaculation

200 to 300 million. But it only takes one at the right place at the right time to make a baby. A low sperm count is considered to be less than 15 million sperm per milliliter of semen.

An average ejaculation volume is 1.5 to 5.0 milliliters.

Average Male Voice Audibility

The average man can be vocally understood at a distance of up to 200 yards; however, measured at night over still water, the maximum distance is 10.5 miles.

Average Penis Size

When flaccid, the average penis length ranges from 2.8 to 3.9 inches (7 to 10 centimeters) and the average circumference is 3.7 inches (9.3 centimeters). When erect, the average penis length for a human male ranges from 4.7 to 6.3 inches (12 to 16 centimeters), and the circumference is 4.6 inches (11.6 centimeters). Measuring your erect penis length and girth is useful for selecting the correct size of a condom.
