BMI is calculated as weight divided by height squared. It does not account for muscle mass or body composition.
About this BMI calculator
This BMI calculator helps you quickly estimate your Body Mass Index (BMI) using your height and weight. BMI is a commonly used indicator to classify body weight into categories such as underweight, normal weight, overweight, or obesity.
The calculation is based on the standard formula: weight (kg) divided by height squared (m²). While BMI is widely used for population-level assessments, it does not take into account muscle mass, bone density, age, or body composition.
This tool provides an indicative result only and should not be used as a medical diagnosis. For health-related concerns or personalized advice, consult a qualified healthcare professional.
All calculations are performed directly in your browser. No personal data is stored, transmitted, or tracked.
