Enter your child's gender, age, height, and weight, along with mother's and father's heights, and the Child Height Predictor calculates their predicted adult height — plus a minimum and maximum expected height range so you know what to realistically expect as they grow.

Predicted heights are usually within 4 inches, taller or shorter, than actual adult height. The accuracy depends on genetic factors and assumes normal growth patterns.
This calculator works for children age 2 and up. For younger children, predictions are less reliable as growth patterns are still establishing.
Height is determined by genetics (60-80%) and environmental factors like nutrition, health, and physical activity. Medical conditions can also impact growth.
The calculator uses the mid-parental height method combined with the child's current growth data. It adds 5 inches to mid-parental height for boys and subtracts 5 inches for girls.
Yes, estimates are less accurate when parent heights are far from average and for children who are unusually short or tall for their age.
The prediction is just an estimate. Talk to your pediatrician if you're concerned about your child's growth pattern or if they're significantly outside normal growth percentiles.
Yes, medical conditions, hormonal issues, nutritional deficiencies, and chronic illnesses can all affect a child's growth and make predictions less accurate.
No, this is an estimate based on current data and genetic factors. Final adult height can vary due to health, nutrition, and other environmental factors during growth years.
