About Penis Size in United States
The average erect penis length in the United States is approximately 13.12 cm (5.16 inches). The CDC and American urological associations consistently report that most American men fall within a normal and healthy range, and that concerns about size are largely driven by unrealistic cultural expectations rather than medical necessity. The American Urological Association defines normal as between 7–17 cm, making the vast majority of men medically average.
