Average Teenage Penis Size Older Ages the average penis size varies for teens, but for most teen aged white males, it is close to the same. If your penis does not grow between ages eight and thirteen, you should go see a doctor. According to recent studies, here is the chart that describes the average length of an American white boy's penis, when NOT erect,(measured in inches) in America. These measurements apply for white males who are five to six feet tall. If you do not fit exactly in this range, do not be worried, unless you are 2+ inches off.

This chart is as of 2007. Research comes from: http://www.virtualteen.org/forums/showthread.php?t=8985
