Healthy Weight Ranges for Boys by Age: A Comprehensive Guide

Weight ranges for boys vary widely due to genetics, growth tempo, activity level, and overall health. The following are approximate average weight ranges (combining kg and lb) by age group:

Age	Average Weight Range
1–2 years	9.5–16 kg (21–35 lb)
3–6 years	13.5–20 kg (30–44 lb)
7–10 years	20.5–31.5 kg (45–69 lb)
11–13 years	33–45.5 kg (73–100 lb)
