Know that you will go through a growth spurt.
You haven’t grown this much since you were a baby. Usually boys start their growth spurt about 2 years after puberty starts. When you are done going through puberty, you will be almost as tall as you will be when you are a grown up.
Maybe you are worried about how tall you are or how tall you will get. How tall you get depends a lot on how tall your mom and dad are. If they are tall, you are likely to be tall. If they are short, you will probably be short too.
You will also start building some muscle. Again, you may be worried that other boys seem to be getting bigger faster. But puberty happens for each boy on their own body schedule. You can’t rush it.
Eat well, sleep well, and stay physically active to help you grow well. Some boys want to lift weights to build muscles. You will not be able to build muscle until you are in puberty. Before puberty, lifting weights will tone your muscles, but you will not build muscles yet.
