BMI calculator
Enter your height and weight to see your body mass index and its standard category.
How it works
BMI is your weight in kilograms divided by your height in meters, squared. The categories are underweight below 18.5, normal up to 25, overweight up to 30 and obese above that. BMI is a rough screening measure and doesn't replace medical advice.
