Calculate your Body Mass Index from height and weight — metric or imperial.
BMI is a general screening measure and doesn't account for muscle mass, bone density, or body composition. It isn't a diagnosis.
Choose Metric or Imperial units, enter your height and weight, then tap Calculate BMI to see your Body Mass Index and its standard category.
What do the BMI categories mean?
Under 18.5 is Underweight, 18.5–24.9 is Normal weight, 25–29.9 is Overweight, and 30+ is Obesity, using the standard WHO ranges.
