What is the average size of a teenagers non erect penis?

The average size of a teenager's non-erect penis can vary widely, but studies suggest it typically ranges from about 2.5 to 4 inches (6.4 to 10.2 cm) in length. Factors such as genetics and age can influence size, with some variation as the individual matures. It's important to remember that there is a wide range of normal sizes, and individual differences are completely normal.
