The average weight of a 4th grader (typically 9–10 years old) can vary based on factors like height, genetics, and overall health. However, general guidelines are:
Boys: Around 65–75 pounds (29–34 kg)
Girls: Around 65–77 pounds (29–35 kg)
It’s important to remember that children grow at different rates, so there’s a wide range of normal. A pediatrician is the best resource for evaluating if a child’s weight is healthy for their age and height.
