BMI Calculator
Calculate Body Mass Index (BMI) from height and weight
Overview
Enter height and weight to calculate BMI (Body Mass Index) and see the WHO classification (underweight, normal, overweight, obese). BMI is simply a ratio of height to weight and does not account for factors like body fat percentage or muscle mass, making it a rough guideline only. Consult a healthcare professional for accurate health assessments.

- BMI does not directly measure body fat, so muscular individuals may be classified as overweight.
- The Asia-Pacific threshold is lower than the WHO standard (BMI 25+ is considered obese).
- These results are reference values only and should not be used as a basis for health decisions or medical judgments. Consult a healthcare professional for an accurate assessment.
FAQ
- Can I be unhealthy even with a normal BMI?
- Yes. BMI is a simple metric based only on height and weight, so it does not reflect body fat distribution, muscle mass, or visceral fat. Even a normal BMI does not guarantee good health. Please consult a healthcare professional for an accurate evaluation.
- Does this BMI scale apply to children and teenagers?
- The classification used here applies to adults aged 18 and over. Children and teenagers require age- and gender-specific growth curve charts.
- Can I use pounds and feet?
- Currently cm/kg units are supported. lb/ft support may be added in the future.
