Quick answer: Child Height Predictor
Mid-parental height method with sex offset plus optional percentile if current height/age entered.
Example: 5'10" dad + 5'4" mom might center son prediction near parental average + son constant.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Child Height Predictor
- Mid-parental adult height estimate with optional growth percentile note.
Genetics explain much but nutrition and hormones matter; charts are WHO/CDC style approximations.
Predicts genetic target height from mother and father heights (cm) with ±8.5 cm band; optional current child height/age for a rough z-score style note - no chart UI.
Inputs on this page: Father height (cm), Mother height (cm), Child sex, Child age (years, optional). Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Child Height Predictor when you need a transparent child height predictor answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) Father height (cm) and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Early puberty shifts growth curves - clinicians use bone age.
- Measure height same time of day barefoot.
- Consult endocrinology if crossing percentiles sharply.
How to use this tool
- 1Enter biological parents’ heights in centimetres.
- 2Optional: child height and age for a rough tracking hint.
- 3Nutrition and health affect growth - pediatrics tracks percentiles on charts.

Key formula explained
How the calculation works
The Formula
Mid-parental target ± residual range; optional Z-score from current height vs age- Father height (cm): the value you enter for father cm.
- Mother height (cm): the value you enter for mother cm.
- Child sex: the value you enter for child sex.
- Child age (years, optional): the value you enter for child age years.
- Child current height (cm, optional): the value you enter for child height cm.
