According to MDHealth, the average height and weight of a 9-year-old boy in the United States is 52.5 inches and 63 pounds.
It is essential to keep in mind that this average can be affected by numerous factors, such as growth spurts that cause children to rapidly gain and lose weight. Using a BMI calculator or chart, one can also consider height and weight.
According to the CDC, the relationship between height and weight and BMI is calculated differently for children and adults, and it varies with age. The CDC cannot provide healthy weight range charts for children because their weight fluctuates in relation to their height growth. Each month, what constitutes a healthy weight for children also changes. In addition, the CDC suggests that BMI does not directly measure body fat, but rather serves as a tool for comparing the height and weight of children of the same gender and age.
WebMD offers a tool for predicting the adult height of a child based on the heights of both parents. If there are concerns about a child’s height or weight, it’s best to consult a paediatrician. There are also multiple BMI calculators for children available online.
