Calculate your Body Mass Index with age and gender-specific interpretation
How to use: BMI (Body Mass Index) is a screening tool to categorize weight status. Select your age group (Adult or Child) and gender for accurate interpretation. Enter your height in feet and inches, then your weight in pounds or kilograms. The calculator shows your BMI number, category (Underweight, Normal, Overweight, Obese), and associated health risks. BMI ranges: Underweight <18.5, Normal 18.5-24.9, Overweight 25-29.9, Obese ≥30. Note that BMI doesn't distinguish muscle from fat, so athletes may show higher BMI despite being healthy.
