⚖️ BMI Calculator
Pop in your height and weight to see your BMI and what it means — metric or imperial, your call.
What this tool actually does
Body Mass Index (BMI) is a quick screening number calculated from your height and weight. It's not a perfect measure of health — it doesn't account for muscle mass, bone density, or body composition — but it's a widely used starting point doctors and health guidelines reference.
This calculator works in both metric and imperial units and never sends your numbers anywhere — everything happens right in your browser.
Frequently asked questions
What do the BMI categories mean?
Under 18.5 is considered underweight, 18.5–24.9 is in the typical range, 25–29.9 is considered overweight, and 30+ falls into the obese range, according to standard WHO guidelines. These are general reference points, not a diagnosis.
Is BMI accurate for everyone?
Not perfectly — BMI doesn't distinguish muscle from fat, so very muscular people can show a higher BMI without excess body fat. It's a useful general indicator, not a complete health assessment.
Should I make health decisions based on BMI alone?
BMI is a starting point, not the full picture. For anything related to your health, it's best to talk to a doctor who can look at the full context.
