Inputs
0 of 3SexUsed by the equation
Patient values are shared with every calculator.
When to use
- Evaluating short or tall stature, alongside the child's height percentile and growth velocity.
Pearls and pitfalls
- A child tracking well below the target range, or crossing percentiles downward, needs evaluation even if the height percentile looks acceptable.
- Use measured parental heights when possible; reported heights are often overestimated.
Why use
Puts a child's height in the context of family stature.
Boys: (father + mother + 13 cm) ÷ 2. Girls: (father + mother − 13 cm) ÷ 2. Target range ±8.5 cm (about ±2 SD)
