About BMI Calculator

Body Mass Index (BMI) is a simple screening tool that estimates body fat using your height and weight. It helps classify weight into categories such as underweight, normal, overweight, and obesity.

BMI is useful for population-level screening, but it does not directly measure body fat or muscle mass. Athletes and older adults may fall outside typical ranges even when healthy.

Quick tips

  • Use consistent units (cm/kg or in/lb) for accurate results
  • Pair BMI with waist measurement or body-fat estimates for better insight
  • Consult a clinician before making major health decisions
