Defining Adult Overweight & Obesity

Weight out of proportion to height is described as overweight or obesity. Body Mass Index (BMI) is a screening tool for overweight and obesity.
Adult Body Mass Index

BMI is a person’s weight in kilograms divided by the square of height in meters.

To calculate BMI, see the Adult BMI Calculator or determine BMI by finding your height and weight in this BMI Index Chart external icon.
  • If your BMI is less than 18.5, it falls within the underweight range.
  • If your BMI is 18.5 to <25, it falls within the healthy weight range.
  • If your BMI is 25.0 to <30, it falls within the overweight range.
  • If your BMI is 30.0 or higher, it falls within the obesity range.
Obesity is frequently subdivided into categories:
  • Class 1: BMI of 30 to < 35
  • Class 2: BMI of 35 to < 40
  • Class 3: BMI of 40 or higher. Class 3 obesity is sometimes categorized as “severe” obesity.
Note: BMI is a screening tool, not a diagnostic tool for health status. A trained MD/DO physician should perform appropriate assessments to evaluate an individual’s health status and risks. If you have questions about your BMI, talk with your personal physician.
See the following table for an example.

Adult Body Mass Index (BMI)
Height Weight Range BMI Considered
5'9" 124 lbs or less Below 18.5 Underweight
125 lbs to 168 lbsc 18.5 to 24.9 Healthy weight
169 lbs to 202 lb 25.0 to 29.9 Overweight
203 lbs or more 30 or higher Obesity
271 lbs or more 40 or higher Class 3 Obesity

BMI does not measure body fat directly, but BMI is moderately correlated with more direct measures of body fat obtained from skinfold thickness measurements, bioelectrical impedance, underwater weighing, dual energy x-ray absorptiometry (DXA) and other methods 1,2,3. Furthermore, BMI appears to be strongly correlated with various adverse health outcomes consistent with these more direct measures of body fatness
