What is the average growth rate of a 13 year old boy?

The average growth rate for a 13-year-old boy is typically around 2 to 3 inches (5 to 7.5 cm) per year, as this age marks the onset of puberty for many boys. Growth patterns can vary significantly, with some boys experiencing growth spurts that may increase this rate temporarily. Factors such as genetics, nutrition, and overall health can also influence growth. It's important to note that individual growth patterns can differ widely.
