1.5cm
The average 14 year old boy is 5"4 or 5"5.
like 5'9 average
My almost 3.5 year old boy is 41 inches tall and 37 pounds
3 to 4 feet
Approximately 5'3 Height is average.
100 pounds
Depends how tall/short they are.
100 cm approx....
The average height of a seven year old boy is about 48 inches.
A 21 -year-old boy? More like a young man. If he is 6ft tall that is 182.88 cm
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.
