What Height Calculator is

A screening adult-height estimate. Mid-parental uses parent heights and sex. Khamis-Roche also uses the child’s age, height, and weight. Metric or US units.

How to use it

  1. Pick mid-parental or Khamis-Roche.
  2. Set units and the child’s sex.
  3. Enter the heights, and the extra fields if you chose Khamis-Roche.
  4. Read the estimate. It is not a medical forecast.

Common uses

A rough adult range for a growth chat or a school form that asks for a predicted height. Diet, illness, and timing of puberty move the real number. This page does not replace a clinician.
