My 7 year old son is 4 foot 8 inches tall and weighs 119lbs where is he on the growth chart?

Greater than 99%: Your son is greater than the 99% for both height and weight for boys his age. This means that basically nobody (or very few) boys are larger than he is at his age. What's even more important is his body mass index (BMI). Here's a way for you to calculate that at the following link: https://nccd.cdc.gov/dnpabmi/calculator.aspx. 99% tile "obese"
