Mid-Parental Height
Tanner genetic target method
target
Likely range:
Based on parents' average height ± 2.5 in (6.4 cm) sex correction. Range = target ± 2 in (5 cm).
Likely Target Range
These are statistical estimates, not guarantees. Nutrition, health, and puberty timing all affect final height.
Summary
Enter both parents' heights and the child's sex to estimate genetic target adult height and its expected range.
How it works
- Enter the father's and mother's heights (feet/inches or cm).
- Select the child's sex.
- The Mid-Parental Height formula averages parent heights and applies a sex correction (+/−2.5 in) to produce a target range.
- The result is a population-level estimate, not a clinical growth assessment.
Use cases
- Get a ballpark adult height estimate at a pediatric checkup.
- Understand how parental height influences a child's growth potential.
- Track how current height aligns with expected adult height over time.
- Discuss growth concerns with a pediatrician using quantitative context.
- Help a child understand their projected height in a fun, educational way.
