Frequently Asked Questions
How accurate is the mid‑parental height prediction?
It gives a statistically reasonable estimate, but many other factors including nutrition, puberty timing and overall health influence final height. The ±8.5 cm range reflects normal variation.
Can I predict my baby's future height?
The formula is designed for children whose parents have reached their adult height. It is less reliable for infants, but it can still give a rough idea of genetic potential once both parents' heights are known.
Does gender affect the height prediction?
Yes. The formula adds 13 cm for boys and subtracts 13 cm for girls to account for the average height difference between adult men and women.
Is Child Height Predictor free and private?
Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
