My son is eight years old and he is 1cm. My 11 year old boy is 156cm. (5ft 1) I am 6ft1 Of course the average size depends on the background and country's average height and weight span. For an 11 year old BOY: 141cm - 158cm (4ft 5- 5ft 2) Don't be scared if your small! You will probably grow bigger after - everyone has different growth rates. A girl once was really tall in my class. 161cm. I was 142cm at the time. I looked like a dwarf. But I grew to be 6ft 1 and she grew up to be 5ft 6! Amazing isn't it! Just eat well, sleep for more than eight hours a day and stay healthy and exercise!
