Penis size: how do you size up to the world?


It’s likely that the penis-size debate will last longer than the U.S. will remain financially solvent.   In the past decade, there has been a lot of data published about the range of penis sizes.  Factors such as age and nationality have been seen as significant in some studies but irrelevant in others.

 So what does this all mean?

 Given that comparing penis size is the most popular thread on (with over 1.5 million views and a few dozen associated threads), I thought it would be appropriate to jump start 2.0 with a series of articles about just that.

 Let’s start by comparing a few studies:

 In the United States:

 Herbenick et al, 10 July 2013

Group: 1,661 erect American sexually active men


Average erect length: 5.57 inches (14.15cm)
Average erect circumference: 4.81 inches (12.23cm)
Different characteristics were not associated with size.

Around the World:

Top 3 Countries with the largest (average penis size)
Republic of Congo: 7.1 inches (18.034 cm)
Ecuador: 7 inches (17.78 cm)
Ghana: 6.8 inches (17.272cm)

Bottom 3 Countries with the smallest (average penis size)
Thailand: 4 inches (10.16 cm)
South Korea: 3.8 inches (9.65 cm)
North Korea: 3.8 inches (9.65 cm)

This data seems like it’s a combination of self-reporting and published studies (which often include self reporting because I imagine it would be really awkward to do all day).

Penis size by age:

I had a lot of anxiety researching “penis size by age” due to a fear of being put on some watch list.

However, I was able to find the following:

Adolescent Health Care: A Practical Guide. These are approximate ranges of non-erect (soft) penises.
Age 10 to 11: 1.6 inches (4 cm) to 3.1 inches (8 cm)
Age 12: 2.0 inches (5 cm) to 4.0 inches (10 cm)
Age 13: 2.0 inches (5 cm) to 4.7 inches (12 cm)
Age 14: 2.4 inches (6 cm) to 5.5 inches (14 cm)
Age 15: 3.1 inches (8 cm) to 5.9 inches (15 cm)
Age 16: 3.9 inches (10 cm) to 5.9 inches (15 cm)
Age 17: 3.9 inches (10 cm) to 6.3 inches (16 cm)
Age 18: 4.3 inches (11 cm) to 6.7 inches (17 cm)

Results seem to be higher than other studies especially considering a non-erect status.

The biggest takeaway would be that if you were 14 and concerned about your size: don’t worry it gets bigger.

If you’re an adult with an erect penis length between 5-6 inches, you’re average.  Stop worrying and get on with your life.
