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.
