BMI Calculator
Body Mass Index (BMI) is a clinical tool used to estimate body fat based on your height and weight. Use our guide to understand your metrics and discover habits for a healthier lifestyle.
Healthy Range Examples
For an average adult with a height of 175cm (5'9"), a healthy weight range is approximately 56.7kg to 76.6kg. For someone at 160cm (5'3"), the range is 47.4kg to 63.7kg. These values aim for a BMI between 18.5 and 24.9, which is the WHO standard for reduced risk of lifestyle-related diseases.

Measure Weight
Record your weight in kilograms on an empty stomach.
Measure Height
Stand tall against a wall and record your height in meters.
WHO Health Classification
The World Health Organization (WHO) provides these standard categories to help people understand their health risks relative to their body weight.
The "Healthy" Benchmark
Research indicates that adults who maintain a BMI between 18.5 and 24.9 have the lowest risk of cardiovascular disease, diabetes, and certain cancers.
- Screening Tool: Screening Tool: BMI is a screening tool, not a diagnostic one. It doesn't measure body fat percentage directly.
- Population Health: Population Health: It is most accurate for "average" adults and helps identify broad health trends.
- Clinical Use: Clinical Use: Doctors use BMI alongside waist circumference and blood pressure for a full health profile.
