BMI Calculator

Get more than a single BMI number — this bundle calculator shows your Body Mass Index category, healthy weight range for your height (BMI 18.5–24.9), and an estimated body fat percentage using the Deurenberg formula. All in one page, with links to our dedicated body fat and ideal weight calculators for deeper analysis.

BMI remains the most searched health metric worldwide. Combining it with ideal weight and body fat estimates keeps users on-page longer and answers the follow-up questions everyone asks after checking BMI: "What should I weigh?" and "How much body fat do I have?"

Supports metric and imperial units. Optional age and gender improve body fat estimation accuracy. Categories follow WHO standards: underweight below 18.5, normal 18.5–24.9, overweight 25–29.9, obese 30+.

BMI does not distinguish muscle from fat — athletes and lifters often read "overweight" despite low body fat. Use the body fat estimate and our US Navy body fat calculator for a fuller picture before setting weight-loss goals.

Screening tool only — not a medical diagnosis. Consult a healthcare provider for personalized advice, especially if you are pregnant, elderly, or managing a chronic condition.
