| Child | Formula (cm) | Formula (inches) |
|---|---|---|
| Boy | (father + mother + 13) ÷ 2 | (father + mother + 5) ÷ 2 |
| Girl | (father + mother − 13) ÷ 2 | (father + mother − 5) ÷ 2 |
The 13 cm adjustment reflects the average height difference between adult men and women. For example, a 5′10″ father and a 5′4″ mother give a predicted height of about 5′9½″ for a son and 5′4½″ for a daughter.
| Age | Boys (median) | Girls (median) |
|---|---|---|
| 2 years | 86 cm (2′10″) | 85 cm (2′9″) |
| 4 years | 102 cm (3′4″) | 101 cm (3′4″) |
| 6 years | 115 cm (3′9″) | 115 cm (3′9″) |
| 8 years | 128 cm (4′2″) | 128 cm (4′2″) |
| 10 years | 139 cm (4′7″) | 138 cm (4′6″) |
| 12 years | 149 cm (4′11″) | 151 cm (5′0″) |
| 14 years | 164 cm (5′5″) | 160 cm (5′3″) |
| 16 years | 174 cm (5′8″) | 163 cm (5′4″) |

Height is one of many traits that run in families. See how coloring is passed down with the baby eye color calculator and the baby hair color calculator, or check your odds of twins with the twins calculator.
Upload one photo of mom and one of dad, and our AI shows your future baby, boy or girl, as a toddler, a kid, a teenager or a grown-up.
See what my baby will look like →This tool uses the mid-parental height method: add both parents’ heights, add 13 cm (5 in) for a boy or subtract 13 cm for a girl, then divide by two. About 95% of children end up within roughly 8.5 cm (3.3 in) of that number.
Genetics explain most of the difference in height, but nutrition, sleep, health and the timing of puberty also matter. The range shown is more meaningful than the single number.
Girls usually reach adult height around 14 to 16, about two years after their first period. Boys typically keep growing until 16 to 18, and some grow a little into their early twenties.
Yes. Choose "Is already here" and enter your child’s age and height. The calculator places them on the CDC growth chart and blends that projection with the parents’ heights, trusting the growth curve more as your child gets older. A bone-age X-ray from your pediatrician is more precise still.
