How much do 11 year olds grow in a year?

On average, 11-year-olds can grow about 2 to 3 inches (5 to 8 centimeters) in a year, though growth rates can vary significantly among individuals. Factors such as genetics, nutrition, and overall health influence growth. During this age, children may also experience growth spurts as they approach puberty, which can lead to more rapid growth in height.
