Child Height Calculator

The calculator uses the mid-parental height method to estimate a child's target height based on both parents' heights, adjusted for sex. For girls: (mother's + father's height − 13) / 2; for boys: (mother's height + 13 + father's height) / 2.

No. The result is a statistical estimate only. A child's final height depends on many factors: diet, sleep, physical activity, health status, and other genetic influences.

The ±8.5 cm range is the interval that covers approximately 95% of children of that sex given the parents' heights. Most children will reach a height between the minimum and maximum values.

Height is mainly determined by genetics (about 60–80%), but nutrition rich in protein and calcium, regular sleep, physical activity, and the absence of chronic illness also play a significant role.

Girls typically stop growing between ages 14 and 16, while boys usually stop between ages 16 and 18. Some individuals may grow slightly longer.

Both parents have nearly equal genetic influence on their child's height. The mid-parental height formula accounts for both parents equally, adding or subtracting a 13 cm correction for sex.

The calculator estimates genetic potential. If you suspect a growth delay or other abnormality, please consult a pediatrician or pediatric endocrinologist.

Not always. The prediction is a statistical value. Environmental factors, chronic illness, or nutritional deficiencies may prevent a child from reaching their full genetic potential.

Mid-parental height (MPH) is a clinical method for estimating a child's target height based on both parents' heights. It is used by pediatricians and endocrinologists as a reference point.

You should consult a pediatrician if your child is growing significantly below the expected range, if the growth rate drops sharply, or if growth stops before the typical age of completion.
