Additional Information

1 - Height and weight ratio charts are not truly accurate measures or indicators, especially for young children and teenagers. Height to weight charts for girls and boys represent only a rough average and should be used in conjunction with a BMI calculator for kids.2 - Young children and teenagers often have growth spurts during their growing years. During puberty your body will grow faster than at any other time in your life. On average, girls commence puberty around ages 10 to 11 and end puberty around 15 to 17 years old; boys start puberty around age 11 to 12 and end around 16 to 17 years of age. During this period it is quite possible to gain and lose weight rapidly, as well as add inches to their heights seemingly overnight. This is particularly so in many adolescent girls who often experience dramatic changes in weight, bone composition, height, and body fat distribution - especially through their pubescent years.3 - Every baby, child, and teenager is different in the way 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 really the best person to consult if you are worried about your childs height to weight ratio as a doctor can use a medical growth chart to keep track of your progress as you mature.
