Many parents wonder whether their child is at a healthy weight. Your pediatrician or healthcare provider will likely use a growth chart to monitor your child's weight at each office visit. While each young person is different, there is an acceptable range of weight based on age -- as well as height -- for your child. The Centers for Disease Control and Prevention provides reference charts to monitor and assess weight in children from age 2 to 20 years.
Based on age alone, a 7-year-old boy weighing between 40 and 72 pounds is within the 3rd to 97th percentile range with most boys -- 50 percent -- weighing 50 pounds. A 7-year-old girl weighing between 39 and 74 pounds is within the same 3rd to 97th percentile range with most weighing 51 pounds. Your child is considered to be at a healthy weight between the 5th and 84th percentile. Your healthcare provider can further assess your child's overall diet and health and provide recommendations for weight loss or gain if needed.
