Please Keep in Mind the Following Facts:

Note: We have a separate Height to Weight Ratio Chart for Adults.

  • Be aware that Height and weight ratio charts are not truly accurate measures or indicators, this is especially so for young children and teenagers.
  • You must always bear in mind that kids and teenagers have growth spurts during their young years. 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.
  • 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” or their “baby fat” as they mature into young adults.
  • In the first year your newborn baby will on average gain 8 ounces in weight each month and have an average growth of around 1/4 to 1/2 inch a month. From birth to the childs first birthday their weight will have tripled.
  • 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.
  • 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.

Height to weight chart now in both Metric and Imperial measurements; Pounds/Kilograms – Inches/Centimeters.
