What is the Height Predictor Calculator & How does it work?
The Height Predictor Calculator uses the mid-parental height formula to estimate a child’s future adult height. This method considers the average height of the parents and adjusts for gender. The prediction includes a confidence interval to reflect variability.For boys, the formula is: Hb = 0.5 * (Hf + Hm) + 6.5, where Hb is the predicted height, Hf is the father’s height, and Hm is the mother’s height. For girls, it is: Hg = 0.5 * (Hf + Hm) – 4.5.
Hb = 0.5 \times (Hf + Hm) + 6.5 \\ Hg = 0.5 \times (Hf + Hm) – 4.5
Hb = Predicted height for boys, Hg = Predicted height for girls, Hf = Father’s height, Hm = Mother’s height
