Calculate Your BMI

Use this calculator to figure out your BMI (Body Mass Index), an estimate of body fat. This calculation is the same regardless of gender or age for people who are at least 18 years old. For children and teens under 18, BMI is determined by using a BMI chart that compares weight and height along with growth charts.

BMI ranges are as follows:

  • Less than 18.5: underweight
  • Between 18.5 & 24.9: normal
  • Between 25.0 & 29.9: overweight
  • 30.0 and above: obese

Please note that BMI does have limitations as it does not account for other factors which may affect a person's weight. It may overestimate or underestimate body fat for people in these categories:

  • Body builders and athletes with a high proportion of muscle mass
  • The elderly (whose height and muscle mass may fall over time), frail people, and those affected by certain illnesses
  • Lactating or pregnant women
