Average weight of boys around 12 years old

[Bobjames200411]

After weighing my son 12 I realised that he was obese but he says that other boys r the same size as him use wondering weather there r that many obese boys out there and the average weight thanks

Dhs nephew was here recently and we had to weigh him for ski hire ( need weight and height). He was 12 in September, 40kg. Not sure if that is more or less for his age but he looks average for his height. Can't remember height exactly but it must have been between 150-155cm as that's the ski height we added

I work with 11/12 year old boys, the 11 year olds are average height, none are especially large and certainly not obese. I have no idea what they weigh. The 12 year olds are all skinny with legs that seem to go on for ever and then a pair of huge feet at the end which are out of proportion with their legs. They are all between about 4 foot 9 and 5 foot 5.
