Quick Answer
To predict a child's adult height: add mother's and father's heights, add 5 inches for boys or subtract 5 inches for girls, divide by 2. This mid-parental height method gives a rough estimate within 4 inches. Example: Mom 5'4" (64") + Dad 5'10" (70") = 134", for a boy: (134+5)/2 = 69.5" (5'9.5"). Genetics, nutrition, and health also affect final height.
Key Facts
- Mid-parental height formula: (Mom + Dad + 5 for boys / -5 for girls) / 2
- Height prediction accuracy: typically within 4 inches of actual
- 1 inch = 2.54 centimeters
- 1 foot = 12 inches = 30.48 centimeters
- Average US male height: 5'9" (175.3 cm); Female: 5'4" (162.6 cm)
- Most growth occurs before puberty; growth plates close around 16-18 (girls) and 18-21 (boys)
- Height is 60-80% determined by genetics
- Bone age X-rays provide more accurate height predictions
Frequently Asked Questions
How do I convert height between units?
1 inch = 2.54 cm, 1 foot = 12 inches = 30.48 cm, 1 meter = 100 cm. To convert feet/inches to cm: (feet × 30.48) + (inches × 2.54). For example, 5'10" = (5 × 30.48) + (10 × 2.54) = 177.8 cm.
How accurate is the child height predictor?
The mid-parental height method predicts adult height within ±8.5 cm (3.3 inches) for about 95% of children. Actual height depends on many factors including nutrition, health, and genetics beyond just parental height.
What is a height percentile?
Height percentile indicates what percentage of the population is shorter than you. At the 75th percentile, you're taller than 75% of people. The 50th percentile is average. Percentiles vary by age and gender.
What is the average height for men and women?
Global averages vary by country. In the US: men average 5'9" (175 cm), women average 5'4" (163 cm). Netherlands has the tallest average: men 6'0" (183 cm), women 5'7" (170 cm). Averages have increased over the past century.
When do people stop growing in height?
Most people stop growing between ages 16-18 (girls) or 18-21 (boys). Growth plates in bones close after puberty ends. Factors affecting growth include genetics, nutrition, sleep, and hormones.
