Both genetic and environmental factors influence height and weight. Teenage children's average height and weight vary by gender, age, race, ethnicity, and nationality. Throughout childhood, a child's body begins to become more proportional. On average, girls commence puberty around ages 10 to 11 and end puberty around 15 to 17. Adolescent girls typically experience dramatic changes in weight, bone composition, height, and body fat distribution - especially through their pubescent years.

Every baby, child, and teenager is different in how they mature and grow during their teen years. Dieting for teens is not recommended, as quite often you will find they will simply "grow out" of their "baby fat" as they mature into young adults. Your pediatrician or family physician is the best person to consult if you are worried about your child's height to weight ratio, as a doctor can use a medical growth chart to keep track of their progress as they mature.
