Height facts & tips

  • Formula accuracy

    Genetic height formulas have about 60–80% accuracy, with a typical range of ±5 cm. The result is an estimate; nutrition, sleep, and exercise also affect final height.

  • Factors that affect height

    Genetics accounts for roughly 60–80% of adult height. Other factors include nutrition (protein, calcium, vitamin D), enough sleep (8–11 hours for children; growth hormone peaks during deep sleep), regular exercise (especially jumping and stretching), and managing chronic illness.

  • Age and growth

    Most height growth happens during puberty. Growth plates usually close in the late teens. A balanced diet and good sleep in childhood and adolescence support reaching genetic potential.

  • Professional assessment

    For a more accurate prediction, doctors can use bone-age X-rays to assess growth potential. If you have concerns about your child's growth, see a pediatrician or endocrinologist.

  • Practical tips

    Encourage adequate sleep, calcium-rich foods, vitamin D, and activities like basketball, swimming, or jumping. These support healthy growth during growing years.
