What is the BMI for Kids Calculator?

The BMI for Kids Calculator helps parents and caregivers assess a child’s body mass index (BMI) based on their age, gender, height, and weight. Unlike adult BMI, children’s BMI is interpreted using age- and gender-specific percentiles because growth patterns differ at various ages. This calculator provides a simplified categorization—underweight, healthy, overweight, or obese—to give a quick insight into a child’s growth and weight status. It also offers guidance for maintaining healthy growth through proper diet and physical activity.

How to Use:

1. Enter Age and Gender: Input the child’s current age in years and select the gender.
2. Enter Height and Weight: Provide height in centimeters and weight in kilograms.
3. Click “Calculate”: The calculator computes the BMI and classifies it into a category.
4. Review the Result: Use the category and tips to support healthy growth and consult a pediatrician for detailed percentile charts if needed.
