    FAQs – Child BMI Calculator

    What is the difference between CDC, WHO, and NHS standards?
    These standards differ in their methodologies and reference populations. The CDC focuses on US-specific data, WHO is globally standardized, and NHS is tailored for the UK. Choose the one that aligns with your healthcare system or interest.
    What age range is this tool suitable for?

    How does the percentile help in understanding my child’s health?
    The percentile compares your child’s BMI to others of the same age and gender. For example, a percentile of 50 means your child’s BMI is higher than 50% of their peers. Percentiles can help monitor growth patterns and detect potential issues early.
