TranslateBMI Calculator
BMI (Body Mass Index) is a quick, widely used screening tool that compares your weight to your height. It's a starting point, not a diagnosis — it can't tell the difference between muscle and fat. Enter your height and weight to see yours.
Enter your height and weight above to see your BMI.
How this is worked out
BMI uses the World Health Organization's standard adult weight categories.
Every figure here is a population average, not a prescription. Hold a target for two or three weeks, track what actually happens, and adjust. If you have a medical condition or are pregnant, talk to a doctor or dietitian rather than a calculator.
Frequently asked questions
What is a healthy BMI range?
The World Health Organization classifies 18.5–24.9 as a healthy weight range, below 18.5 as underweight, 25–29.9 as overweight, and 30 and above as obesity.
Does BMI account for muscle mass?
No — BMI only compares weight to height, so a muscular build can land in a higher BMI band without carrying excess fat. It's a screening tool, not a diagnosis.
