What is the average 14 year old boy's penis length?

The average penis size for a 14-year-old boy can vary significantly due to individual development and puberty timing. Generally, studies suggest that the average erect penis size for boys in this age group ranges from about 4 to 5 inches (10 to 12.7 cm). It's important to note that there is a wide range of normal sizes, and variations are completely normal during this stage of development.
