Frequently asked questions
- What is a healthy BMI?
- For most adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.
- Is BMI accurate for everyone?
- BMI is a quick screen, not a full picture. It does not separate muscle from fat, so very muscular people can read as "overweight," and it works differently across ages and ethnicities.
- Is this medical advice?
- No. These calculators are for general information and education only. They are not a diagnosis or a substitute for professional care — talk to a doctor or qualified clinician about your health.
