What Is a Growth Spurt?
Quick Answer
A growth spurt is a period of time when your body grows much faster than usual, especially in height. Growth spurts are most common during puberty, when kids can grow several inches in just one year. They are a totally normal part of growing up and are the reason you might suddenly need new clothes and shoes.
Explaining By Age Group
Ages 3-5 Simple Explanation
You know how you keep outgrowing your shoes and clothes? That is because you are growing! Sometimes your body grows extra fast, and that is called a growth spurt. It is like your body is in a hurry to get bigger.
You know how some plants seem to shoot up really fast after it rains? Your body can do something similar. During a growth spurt, you might get taller really quickly, and everybody starts noticing how much you have grown.
You know how sometimes your legs might feel a little achy at night? That can happen when your body is growing. Those little aches are sometimes called growing pains, and they go away on their own. It just means your body is busy getting bigger.
You know how every kid in your class is a different height? That is because everyone grows at their own speed. Some kids have their growth spurts early and some have them later. But everyone grows, and that is the fun part!
Ages 6-8 More Detail
A growth spurt is when your body grows a lot faster than it usually does. You are always growing little by little, but during a growth spurt, you might grow several inches in a pretty short time. This is most common during puberty, when your body is changing from a kid's body into an adult's body.
During a growth spurt, you might notice that your pants get too short, your shoes feel tight, and your shirts do not fit the way they used to. It can feel like your clothes are shrinking, but really, you are just getting bigger! Some kids grow so fast they need new shoes every few months.
Growth spurts can sometimes come with some side effects. Your joints and muscles might ache, especially in your legs at night. These are called growing pains. You might also feel hungrier than usual because your body needs extra fuel to do all that growing. Eating healthy food and getting plenty of sleep helps a lot.
Girls often have their biggest growth spurt between ages 10 and 14, while boys usually have theirs between ages 12 and 16. That is why you might notice that some kids in your class are suddenly a lot taller than others. Everyone catches up eventually.
Your hands and feet often grow before the rest of you, which can make you feel a little clumsy for a while. That is totally normal and temporary. Once the rest of your body catches up, things start to even out again.
Ages 9-12 Full Explanation
A growth spurt is a period when your body grows at a much faster rate than usual. While you are always growing gradually, puberty brings a big acceleration. During a major growth spurt, you can grow anywhere from 2 to 5 inches in a single year, which is a lot more than the 2 inches per year that is typical during childhood.
Growth spurts are triggered by the same hormones that cause the other changes of puberty. Growth hormone and sex hormones work together to signal your bones to lengthen, especially the long bones in your legs and arms. This is why one of the most obvious signs of a growth spurt is suddenly needing longer pants.
An interesting thing about growth spurts is that different parts of your body grow at different rates. Your hands and feet tend to grow first, followed by your arms and legs, and finally your torso. This uneven timing is why you might feel a bit awkward or clumsy during a growth spurt — your body is literally still catching up with itself.
Girls typically experience their peak growth spurt between ages 10 and 14, often around the time they start their period. Boys tend to hit their peak growth spurt a bit later, usually between ages 12 and 16. This is why many girls are taller than boys in middle school, but boys often catch up and pass them in high school.
Growth spurts can come with some physical discomfort. Many kids experience growing pains, which usually feel like a dull ache in the legs, particularly at night. You might also feel hungrier than usual as your body demands more calories and nutrients to support all that rapid growth. Making sure you eat balanced meals, drink enough water, and get 8 to 10 hours of sleep is especially important during this time.
Eventually your growth spurt will slow down and stop. Most girls reach their full adult height by around ages 14 to 16, and most boys by around ages 16 to 18. Your final height depends mainly on genetics, nutrition, and overall health. Whatever height you end up at, it is uniquely yours.

Tips for Parents
A growth spurt can be a challenging topic to discuss with your child. Here are some practical tips to help guide the conversation:
DO: Follow your child's lead. Let them ask questions at their own pace rather than overwhelming them with information they haven't asked for yet. If they seem satisfied with a simple answer, that's okay — they'll come back with more questions when they're ready.
DO: Use honest, age-appropriate language. You don't need to share every detail, but avoid making up stories or deflecting. Kids can sense when you're being evasive, and honesty builds trust.
DO: Validate their feelings. Whatever emotion your child has in response to learning about a growth spurt, acknowledge it. Say things like 'It makes sense that you'd feel that way' or 'That's a really good question.'
DON'T: Don't dismiss their curiosity. Responses like 'You're too young for that' or 'Don't worry about it' can make children feel like their questions are wrong or shameful. If you're not ready to answer, say 'That's an important question. Let me think about the best way to explain it, and we'll talk about it tonight.'
DO: Create an ongoing dialogue. One conversation usually isn't enough. Let your child know that they can always come back to you with more questions about a growth spurt. This makes them more likely to come to you rather than seeking potentially unreliable sources.
Common Follow-Up Questions Kids Ask
After discussing a growth spurt, your child might also ask:
How much can you grow during a growth spurt?
During a major growth spurt in puberty, many kids grow about 2 to 5 inches in a single year. Some kids may grow even more. The amount you grow depends on your genetics and overall health.
Are growing pains real?
Yes, growing pains are real and quite common. They usually feel like an ache or throb in the legs, especially at night. Stretching, massage, and a warm compress can help. Despite the name, doctors are not entirely sure they are directly caused by growing, but they do tend to happen during growth spurts.
Why am I so hungry all the time during my growth spurt?
Your body needs extra energy and nutrients to support all that rapid growth. Your bones, muscles, and organs are all developing quickly, and that takes a lot of fuel. Eating regular, balanced meals with plenty of protein, fruits, vegetables, and whole grains will help your body get what it needs.
Why are my feet so big compared to the rest of my body?
During a growth spurt, your hands and feet tend to grow first before the rest of your body catches up. It is a normal part of how your body grows, and the rest of you will eventually even out. This is also why you might feel a bit clumsy for a while.
When do you stop growing taller?
Most girls reach their full height by around ages 14 to 16, and most boys reach theirs by around ages 16 to 18. After that, the growth plates in your bones close and you stop growing taller, though your body may continue to change in other ways.
