A 7 year old boy should be about "49 to "55
As tall as any other Caucasian 13-year old boy in the world.
About 5 feet.
Four foot eleven
I would say the average 16 year old boy would probably be somewhere between 5'8-6'
Studies show that the average 11 year old boy should be at least 7 foot tall
100 cm approx....
The average height of a seven year old boy is about 48 inches.
There really is no specific limit to how much a fourteen year old boy should weigh. It depends on how tall you are, because if you were 5' 9", you should weigh more than a fourteen year old boy who is 5' 2".
Between 5' 6" & 6" IMO.
I think that a 14 year old boy will stand at 5.9 foot - 6.1 that is the average and that what i think a 14 year old will be in 20 years.
he should be 20 feet tall
