5. Frequently Asked Questions (FAQs)

Is BMI an accurate measure of health?

BMI is a useful screening tool for identifying potential weight problems in adults. However, it’s not a perfect measure of body fatness and doesn’t account for factors like muscle mass, bone density, or fat distribution. For example, a very muscular person might have a high BMI but be perfectly healthy. It’s best used as a general guide and in conjunction with other health metrics.

Is BMI interpreted differently for children and teens?

Yes. For individuals under 20, BMI is age- and sex-specific because body fat changes with age and differs between boys and girls. Instead of fixed categories, BMI for children is plotted on percentile charts. This calculator is designed for adults aged 20 and over.

Why is age and gender included in the calculator?

While the core BMI formula only uses height and weight, age and gender are important contextual factors for interpreting health risks. Body composition can vary significantly with age and between sexes. We include these inputs to provide a more tailored interpretation in future updates and to align with standard health data collection practices.

What is a “healthy” BMI range?

For most adults, a healthy BMI is considered to be between 18.5 and 24.9. A BMI below 18.5 is categorized as underweight, 25.0 to 29.9 is overweight, and 30.0 or higher is categorized as obese.

Is my data saved anywhere?

No. Your privacy is paramount. All calculations happen entirely within your web browser. We do not track, send, or store any of the personal information you enter into the calculator.
