How accurate is the future height prediction?

Accuracy depends on the child's age - predictions are more reliable for older children (14+) with high confidence, while younger children have lower confidence due to more remaining growth years.

At what age do predictions become most accurate?

Predictions become most accurate after age 14 for boys and 12 for girls, as these children are approaching their final growth spurts and adult height.

What factors can affect the prediction accuracy?

Nutrition, health conditions, genetics, hormonal factors, early/late puberty, and family growth patterns can all influence whether a child reaches their predicted height.

Why do boys and girls have different prediction formulas?

Boys typically continue growing until age 18 while girls usually complete growth by age 16, requiring different calculations for accurate height predictions.

Should I be concerned if my child isn't growing as predicted?

Growth predictions are estimates with ranges. If you have concerns about your child's growth pattern, consult with a pediatrician for professional assessment.
