Percentiles show how your child's height compares to others of the same age and gender. The 50th percentile means half of children are taller and half are shorter.
Children usually follow their growth curve. If they change percentiles significantly, it may indicate a growth issue to discuss with your pediatrician.
Predictions are based on CDC growth charts and statistical modeling. Genetics are the main factor, but nutrition and health also play important roles.
Our height predictor uses CDC growth charts and statistical modeling to provide estimates with approximately 80-90% accuracy. Predictions are most accurate for children following typical growth patterns. Genetics, nutrition, and health factors can influence final adult height.
The height calculator works best for children aged 2-20 years, as this is the range covered by CDC growth charts. Predictions are most accurate during steady growth periods and less reliable during growth spurts.
Height percentiles compare your child's height to other children of the same age and gender. The 50th percentile means half of children are taller and half are shorter. The 95th percentile means your child is taller than 95% of children their age.
Small changes in percentiles are normal, but significant drops or jumps may indicate growth issues. Always consult your pediatrician if you notice concerning changes in your child's growth pattern or if your child drops more than two percentile lines.
Yes, our calculator provides adult height predictions based on current height, age, and growth patterns. However, these are estimates - actual adult height can vary due to genetics, nutrition, health, and other factors. Predictions become more accurate as children approach their final adult height.
