Medical Disclaimer

Effective date: October 13, 2026

The BMI calculator and all content on bmicalculatoronline.info (the “Site”) are provided for general information and education only. Nothing on the Site is medical advice, and using the Site does not create a doctor-patient or any other professional relationship.

BMI Is a Screening Measure, Not a Diagnosis

Body mass index compares weight with height. It does not measure body fat directly and does not take into account muscle mass, bone density, body shape, age, sex or ethnicity. As a result, BMI can be misleading for some people, including:

  • athletes and very muscular people
  • pregnant or breastfeeding women
  • older adults
  • people of some ethnic backgrounds, for whom lower cut-off points are often recommended (the calculator offers an Asian cut-off option for this reason)
  • children and teenagers, whose BMI must be read against age and sex percentile charts rather than the adult categories

Talk to a Health Professional

Always ask your doctor or another qualified health professional about your weight, health, diet, exercise or any medical condition, and before making changes based on what you read here. Never ignore professional medical advice or delay seeking it because of something on the Site.

If you think you may have a medical emergency, call 911 or your local emergency number immediately.

No Guarantee of Accuracy

We work to keep the calculator and information accurate and up to date, but we make no guarantees about completeness, accuracy or suitability for your situation. Results depend on the values you enter. You use the Site and its results at your own risk, as set out in our Terms and Conditions.

External Links and Advertising

The Site may link to other websites and show advertising. We do not endorse, and are not responsible for, third-party content, products or services.
