Can you make a child grow taller?

Height is about 80% genetic, but the remaining ~20% — the environment — is where parents can help. The goal is not to defy genetics; it is to let your child reach the top of their genetic range. Below is an evidence-based overview, with each point linking to a detailed guide. To see your child's estimate first, try our free height calculator.
Genetics sets the range; environment fills it

Roughly 80% of height is genetic and 20% environmental, so even shorter parents can help a child reach the upper end with good habits. More: genetics vs environment in height.
Nutrition — the raw material for growth

Protein, calcium, and vitamin D are the building blocks; deficiency limits growth. See a diet plan to help your child grow taller. If your child eats well but is not growing, absorption may be the issue.
Sleep — children grow while they sleep

Growth hormone is closely tied to sleep. The popular "10 p.m. rule" is overstated — what matters is enough, regular sleep rather than a magic hour. See how much sleep kids need to grow.
Exercise — stimulate the growth plates

Weight-bearing activity like jumping and skipping stimulates the growth plates. See which exercises help most.
Remove the growth-stealers

Sometimes removing obstacles matters more than adding effort. Childhood obesity can trigger early puberty and shorten the growth window; precocious puberty closes the plates early; and chronic stress raises cortisol, which suppresses growth.
The golden window — act before the plates close

The same effort works best while the growth plates are open. See the best ages to grow taller. Assuming a child "will grow later in their teens" often means missing the window.
When to see a doctor

Optimize at home, but seek a check if the predicted height is low, if your child is slipping down the growth chart, or if puberty seems early. Remaining growth can only be judged by a bone-age X-ray; see what age to see a growth specialist. This article is general information; diagnosis is confirmed at an in-person visit.
FAQ
Can my child grow taller than their parents?
Yes. Genetics sets a range, and good nutrition, sleep, exercise, and avoiding early puberty can push a child toward the top of that range.
Is there a food or exercise that makes kids taller?
No single food or exercise adds height on its own. They help by removing deficiencies and stimulating growth within the child's genetic potential.
When should I take my child to a doctor?
If the predicted height is low, the growth-chart percentile is falling, or puberty seems early, a bone-age X-ray and clinical check are the reliable next step.
