BMI Calculator

BMI (Body Mass Index) is a measure of body fat based on height and weight. It's calculated using the formula: BMI = weight (kg) / height (m)². BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

According to WHO standards: Underweight (BMI < 18.5), Normal weight (BMI 18.5-24.9), Overweight (BMI 25-29.9), and Obese (BMI ≥ 30). These categories help assess health risks associated with different weight ranges.

BMI doesn't distinguish between muscle and fat mass, so athletes or muscular individuals may have high BMI despite low body fat. It also doesn't account for fat distribution, age, sex, or ethnicity differences. BMI should be used alongside other health assessments.

Ideal weight corresponds to a BMI between 18.5-24.9. The calculator shows your ideal weight range based on your height. This range represents weights associated with the lowest health risks for most people.

Our BMI calculator uses the standard WHO formula and is mathematically accurate. However, BMI is a screening tool, not a diagnostic measure. For comprehensive health assessment, consult healthcare professionals who can consider additional factors.
