The child height predictor uses parent heights and child sex for a mid-parental height range in centimeters—genetics only, not bone-age or endocrine workups.
How to use
- Choose child sex.
- Enter mother and father height (cm).
- Read mid-point and low–high band (~±8.5 cm).
Example
Girl, father 175 cm, mother 162 cm → mid ~166 cm, band ~157.5–174.5 cm (rounded).

Frequently asked questions
How is adult height predicted?
Mid-parental height from parent heights and child sex—a cm range. Genetics are only part of the story.
Barefoot height?
Use accurate barefoot cm measurements. Missing one parent widens uncertainty.
Predicted shorter than peers?
Ranges are wide—current height ≠ final height. Medical workups (bone age, etc.) beat any online formula.
Use with BMI?
Height range = genetic band; child BMI = current weight-for-height screen.
Is this medical advice?
No—results are for planning reference only. See clinicians for pregnancy, pediatrics, cycle disorders, or sleep conditions. Do not rely on calendar math alone for contraception.
