Click "Calculate" to see your BMI value and the corresponding weight category.
BMI applies to adults aged 20 and older. For children and teens, age-specific percentiles should be used instead.
BMI is calculated by dividing weight in kilograms by the square of height in meters:
BMI = weight (kg) / height (m)^2
Categories: Underweight < 18.5, Normal 18.5 – 24.9, Overweight 25 – 29.9, Obese ≥ 30.
Example: A person weighing 70 kg with a height of 175 cm.
A healthy BMI falls between 18.5 and 24.9 according to the World Health Organization. Values outside this range may indicate increased health risks.
No. BMI does not distinguish between muscle and fat. Athletes with high muscle mass may have an elevated BMI despite having low body fat.
The standard BMI formula is intended for adults aged 20 and older. For children and adolescents, BMI-for-age percentiles are used instead.
BMI is a screening tool, not a diagnostic measure. It correlates with body fat at a population level, but individual health assessments should include other factors like waist circumference, blood pressure, and blood tests.
