Why adult BMI categories don’t apply
Kids are growing. Body composition changes by age, and patterns differ between boys and girls. That’s why pediatric BMI uses percentile charts.
What you need to calculate pediatric BMI properly
- Age (in months or exact age)
- Sex
- Height
- Weight
Do not publish a “kids BMI calculator” with adult cutoffs
That’s misinformation. It will hurt trust and your site’s credibility. If you build the kids tool later, it must output percentile.
