Accurate & Free BMI Calculator for Kids
Understanding your child’s weight is crucial for their overall health and development. Our BMI Calculator for Kids helps parents and caregivers determine whether a child’s weight falls within a healthy range based on their age, height, and weight. This tool follows CDC (Centers for Disease Control and Prevention) and WHO (World Health Organization) growth standards to provide an accurate BMI calculation for children and teens.
What is BMI for Kids?
Body Mass Index (BMI) is a widely used tool to estimate body fat based on height and weight. However, unlike adult BMI, children’s BMI is age- and gender-specific because their body composition changes as they grow.
To accurately assess a child’s BMI, the calculation considers:
- Age (2 to 19 years old)
- Gender (boys and girls have different growth patterns)
- Height and Weight
How to Use the BMI Calculator for Kids?
- Enter the child’s weight – in kilograms (kg) or pounds (lbs).
- Enter the child’s height – in centimeters (cm) or feet & inches.
- Select age and gender – as BMI for children is age-specific.
- Click “Calculate BMI” – Instantly get the child’s BMI percentile ranking.

BMI Percentile Chart for Kids
| BMI Percentile | Category |
|---|---|
| Below 5th percentile | Underweight |
| 5th – 84th percentile | Healthy Weight |
| 85th – 94th percentile | Overweight |

💡 Note: Since children grow at different rates, BMI is interpreted using percentiles rather than fixed numbers. A child’s BMI percentile shows how their BMI compares to other children of the same age and gender.
Why is BMI Important for Kids?
- Helps monitor healthy growth and weight development.
- Identifies potential health risks related to underweight or obesity.

- Growth spurts can temporarily affect BMI percentiles.
- Always consult a pediatrician for a complete health assessment.
