Synopsis: This reference tool provides standardized growth data for male children between two and twelve years of age, drawing from authoritative sources including the World Health Organization, the National Institutes of Health's Gerontology Research Center, and the U.S. Centers for Disease Control and Prevention. The chart breaks down expected height and weight measurements by year, accounting for the typical growth spurts boys experience between ages nine and fifteen, when weight gain averages eight to ten pounds annually. Parents and caregivers of children with developmental delays, genetic conditions affecting growth, or other disabilities will find this particularly valuable for monitoring whether their child falls within expected ranges or requires additional medical attention, though the data emphasizes that individual variation is normal and pediatric consultation remains essential for accurate assessment - Disabled World (DW).
Introduction
There is quite often a sudden spurt of growth in young boys between 9 to 15 years of age, with a gain in weight of around 8 to 10 pounds per year. However, it is important to keep in mind that many children in this age group are experiencing a pubertal growth spurt, and it may appear they are overweight (by weight-for-age) when, in fact; they are just tall. Normal growth for male kids is classified within a range that pediatricians use to assess a child's developmental progress. The following table represents typical weight and height ranges for 2 to 12 year old boys.

Insights, Analysis, and Developments
Editorial Note: Growth charts serve as guideposts rather than absolutes, reminding us that children develop along their own timelines. While these WHO, NIH, and CDC measurements offer reassurance when a child tracks within expected ranges, they also help identify when something deserves a closer look from a healthcare provider. For families raising children with disabilities or chronic conditions, having reliable baseline data becomes even more critical - not to chase some arbitrary ideal, but to catch potential complications early and ensure every child receives the nutrition and care they need to reach their own potential. These numbers tell part of the story, but the pediatrician's trained eye completes the picture - Disabled World (DW).
