There is no simple answer since the height will depend, among other things on the inherited genes - particularly from parents and grand parents, the ethnic origins and the health and nutrition since conception.
A thirteen year old boy should be at least 150 cm in height.If you are above 150, its normal but below it....

At 15 years old, Brooklyn is currently a tall boy at a height of 5'9. He is almost as tall as his dad who is only 6 feet.
No. That is extremely tall for an 11 year old, most boys don't reach that height until they are at least 14-15 years old.
If the boy is four years old and his sister is three times as old, then she is 12 years old. The age difference between them is 8 years (12 - 4). When the boy is 12 years old, his sister will be 12 + 8, which makes her 20 years old.
