Growing body

Growth spurts: your own timetable

During puberty most people go through a growth spurt. It comes at different times for different people. Learn what to expect and why comparison is unfair.

What is a growth spurt?

A growth spurt is a time of fast growth during puberty. You may grow several centimetres in a year.

Girls often have their growth spurt earlier, around 10 to 14. Boys often have theirs a bit later, around 12 to 16. Many girls are taller than boys in the same class for a few years, then boys catch up.

Everyone has their own timetable

Your height depends on your family's genes, your food, sleep and health. When your growth spurt comes is also partly inherited.

Growing early or late is not better or worse. Early growers do not always end up tallest, and late growers often catch up.

Comparing yourself to cousins or classmates is unfair, because you are all on different timetables.

Growing pains and clumsiness

Hands and feet often grow first, so you may feel clumsy for a while. Your brain needs time to catch up with your new size.

Some children get aching legs in the evening or at night. These are often called growing pains and usually go away with rest or a gentle massage.

Helping your body grow

Good food, enough sleep and regular activity help you reach the height your body is meant to be.

There are no tablets, powders or exercises that will make a healthy child grow much taller. Be careful of advertisements that promise this.

Key points

  • A growth spurt is a period of fast growth during puberty.
  • Girls often grow earlier than boys, and boys usually catch up.
  • Timing is partly inherited and is not a race.
  • Food, sleep and activity support healthy growth.

Myth or fact?

Myth

Hanging from a bar or special powders will make you much taller.

Fact

Height is mostly decided by genes and healthy habits. Products promising extra height do not work and may be unsafe.

Myth

If you are short now, you will always be short.

Fact

Many people grow a lot later in their teens. Your final height is not decided by your height today.

When to get help

  • See a doctor if leg pain is in one leg only, happens during the day, causes limping, or comes with swelling, redness or fever.
  • If you or your family are worried that you are growing much more slowly than others, a doctor can check your growth.
  • If you are teased about your height or size, tell a trusted adult.
