The average height of a seven year old boy is about 48 inches.
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
The average 14 year old boy is 5"4 or 5"5.
1.5cm

i would say the Average would be somewhere between 4'11-5'3
it depends on how tall you are or how big you are but it should be about 86 pounds
A 7 year old boy should be about "49 to "55
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.
like 5'9 average
As tall as any other Caucasian 13-year old boy in the world.
