Synopsis: Comprehensive charts displaying average height-to-weight ratios for children and teens, using both imperial (inches/pounds) and metric (cm/kg) measurements, organized by age.
Why it matters: These height-to-weight ratio charts offer valuable reference data for parents, healthcare providers, and researchers to assess and monitor the growth patterns of infants, children, and teenagers. The charts, which include both imperial and metric measurements, present average height and weight ranges for various age groups from birth to 20 years old, separated by gender. While not a definitive measure of health, these charts serve as a useful tool for identifying potential growth issues or developmental concerns, allowing for early intervention when necessary. The information is based on data from reputable sources such as the World Health Organization and the U.S. Centers for Disease Control and Prevention, providing a reliable benchmark for understanding typical growth trajectories across different stages of childhood and adolescence - Disabled World.
Introduction
If you are over 20 years of age you will need to refer to our Adults Height to Weight Chart as our optimum height-to-weight ratio charts below only provide data from newborn babies to teenage girls and boys. The tables will give you a general idea of whether you are of average weight for your age and height without using complicated percentile graphs and charts.
Main Item
Height and weight ratio charts are not truly accurate measures or indicators, especially for younger children and teenagers, as they represent only a rough average and should be used in conjunction with a BMI calculator for kids. Our height-to-weight charts below display both Metric and Imperial measurements, i.e., Pounds to Kilograms and Inches to Centimeters.

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.
*Information and data for above growth charts sourced from The World Health Organization (WHO), Gerontology Research Center (National Institutes of Health (NIH), USA), and the U.S. Centers for Disease Control and Prevention (CDC).
