Pediatric BMI Calculator
Calculate your child’s Body Mass Index (BMI) and growth percentile. Track development and understand healthy weight ranges for children and teenagers.
Step 1: Child Information
Measuring Height Accurately
Measure without shoes, standing straight against a wall. For infants under 2 years, measure while lying down.
Step 2: Weight & Calculation
Understanding Pediatric BMI

Understanding Percentiles
A percentile shows how your child compares to others of the same age and gender. For example, the 75th percentile means your child weighs more than 75% of children their age and gender.
BMI Categories for Children
| BMI Category | Percentile Range | Description |
|---|---|---|
| Underweight | Less than 5th percentile | Below healthy weight range |
| Normal Weight | 5th to 85th percentile | Healthy weight range |
| Overweight | 85th to 95th percentile | Above healthy weight range |
| Obese | 95th percentile and above | Significantly above healthy weight |
BMI Formula
BMI = weight (kg) ÷ height (m)². For children, this number is then compared to growth charts specific to age and gender.
