Tool usage guide
The BMI Calculator for Children provides an accurate way to assess body mass index for individuals aged 2 to 20, utilizing age and gender-specific growth charts to determine weight status percentiles.
Background
A parent wants to track their 10-year-old son's growth progress at home.
Problem
The parent is unsure if their child's weight is appropriate for his current height and age.
How to use
Input the child's age (10), gender (Boy), and current height (130 cm) and weight (30 kg).
Outcome
The calculator provides the BMI value and the corresponding percentile, helping the parent understand where the child stands relative to peers.
Children are still growing, so their BMI must be interpreted relative to other children of the same age and gender using percentile charts.
This tool is designed for children and adolescents between the ages of 2 and 20 years old.
Yes, the calculator supports both metric (kg, cm) and imperial (lb, ft/in) measurement systems.
The percentile indicates how a child's BMI compares to the reference population; for example, the 50th percentile is the median BMI for that age and gender.
