BMI cannot separate muscle, fat, bone, or differences in body shape.

Step 1
Calculate your starting point
Before you calculate
- Enter your current weight in kilograms.
- Enter your height in centimeters.
- Read the result as a broad category, not a diagnosis.
Add the missing context
Look beyond one body-size number
BMI is a broad screening measure. It becomes more useful when viewed alongside habits, strength, energy, health history, and professional guidance.
Review daily patterns
Food quality, movement, sleep, stress, and consistency add valuable context.
Avoid one-day judgments
Longer-term patterns are usually more informative than one measurement.
Discuss concerns
A qualified professional can interpret the result with your health history.
