How This Is Calculated

BMI is your weight in kilograms divided by your height in metres squared. The World Health Organization adult categories are:

  • Under 18.5: underweight
  • 18.5–24.9: healthy weight
  • 25–29.9: overweight
  • 30 and over: obese

BMI is a quick screening tool, but it can't tell muscle from fat. Muscular people can score as overweight, and some ethnic groups have higher health risks at lower BMIs. It isn't meant for children or pregnant women. For a better picture, try the body fat calculator.
