BMI Calculator
Estimate your Body Mass Index (BMI) from your height and weight, using the standard WHO adult categories.
WHO adult BMI categories: below 18.5 underweight · 18.5–24.9 normal weight · 25–29.9 overweight · 30 and above obese.
BMI is a general screening measure, not a diagnosis — it doesn’t account for muscle mass, body frame, age, or pregnancy, and shouldn’t be used alone to judge anyone’s health. For a full, personal assessment, please talk to a doctor.
