How the Height Projection Formula Works
1. Mid-Parental Height
The Tanner Mid-Parental formula averages the parents' heights, adding 13 cm for boys or subtracting 13 cm for girls to account for biological sexual dimorphism.
2. WHO Percentile Curves
Comparing height against WHO growth percentiles identifies whether a child is growing steadily along their individual genetic growth canal.
3. Growth Velocity
A child's trajectory along the WHO curve is often more clinically meaningful than any single height reading.
