BMI Calculator

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.

How it works

BMI is calculated by dividing your weight in kilograms by your height in meters squared. It provides a reliable indicator of body fatness for most people.

Categories

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 - 24.9
  • Overweight: BMI 25 - 29.9
  • Obese: BMI 30 or greater

Gender Differences

The BMI formula is the same for men and women, but body composition differs significantly. Women naturally have ~10% more body fat than men at the same BMI.

Limitations

  • Athletes with high muscle mass may have a high BMI but low body fat
  • Older adults may have normal BMI but low muscle mass
  • BMI doesn't account for body composition or fat distribution
  • Different ethnic groups may have different health risk thresholds
