Jul 17, · Predicted heights are usually within 4 inches, taller or shorter, than actual adult height. Medical conditions and other factors can affect a child's growth.
This free height calculator predicts a child's adult height based on linear regression analysis. It can also convert between different units of height. In addition, explore hundreds of other calculators addressing fitness, health, math, finance, and more. Based on this genetic factor, you can estimate your child's adult height by adding Mom's and Dad's heights (in inches), dividing that number by two, and adding inches for boys or subtracting inches for girls. Another rule of thumb is that a person's height when full grown is .
The Mid-Parent Rule is a simple formula to calculate adult height. It is based solely on the height of the parents and the child's gender. The height of the opposite gender parent is adjusted or multiplied by a factor. For fathers, the factor is 12/ For mothers, the factor is 12/ The increase in adult weight per relative birth weight category was greatest for infants who were both heavy and long at birth. Conclusions: Birth length is perhaps a better predictor of adult height and weight than birth weight, and should be considered as a possible risk factor for adult morbidity and mortality.
Divide by two. Another way to estimate a child's adult height is to double a boy's height at age 2 or a girl's height at age 18 months. Remember, a child's height is largely controlled by genetics. It's also important to note that children grow at different rates.

Other methods for predicting a child's adult stature. A number of methods for height prediction relying on examinations of skeletal structure are often used by pediatricians, for example the Bayley-Pinneau , the Roche-Wainer-Thissen RWT  and the Tanner-Whitehouse 3 method .However, all these methods are subject to a wide range of error, at least partly because of the use of bone age. Jan 27, · A simple method to predict adult height is to double the child's height at age 2. Girls develop more quickly, so doubling their height at 18 months old can also be used as an estimate of how tall they will be as adults. While this method has been around for a long time, no research exists to demonstrate its accuracy.
