Pediatric Growth & Height Predictor
Predict your child's future adult height based on genetics, or evaluate infant growth percentiles against official WHO standards.
This baby-percentile page opens the infant growth workflow first, comparing weight and length against reference percentile curves. It is a screening estimate, not a pediatric diagnosis.

Frequently Asked Questions
What is the Mid-Parental Height formula?
The mid-parental height formula adds maternal and paternal heights, adjusts for the child's sex (+13cm for boys, -13cm for girls), and divides by two. This yields a target height that aligns with the couple's genetic potential.
How accurate is genetic height prediction?
It acts as a statistical center-point. Most children (95%) will end up within +/- 8.5 cm (3.3 inches) of the predicted target, though nutrition, exercise, and health play crucial roles.
What does a baby percentile mean?
If your baby is in the 75th percentile for weight, it means they weigh more than 75% of healthy babies of the same age and sex in the WHO reference database, and less than 25%.
