For a ten year old boy, I think they should weigh 75 to 80


It depends more on their height than their age. Their body mass

index (BMI) can be a reasonable measure of whether they are at a

suitable weight. It can be calculated by dividing their weight in

kilogrammes by their height in metres squared, and comparing the

answer to values given on a chart. (There are charts available for

free from many websites with a quick search, E.g. one is available

on the wikipedia page for BMI

So if for example the 10 year old was 1.2 metres tall and

weighed 40 kilogrammes, their BMI would be:

1.2 x 1.2 = 1.44

40 ÷ 1.44 = 27.78 (Overweight according to the chart)

Bear in mind that the chart isn't always completely reliable,

for example a very muscular person may be classified as overweight

due to the weight for their height.
