BMI Calculator

Body mass index (BMI) is a measure of body fat based on height and weight that applies to both adult men and women. Higher BMI numbers are associated with increased risks of disease and death, from conditions such as cardiovascular disease, type 2 diabetes and some cancers. Research has found that the lowest and highest BMIs are associated with highest risks.

BMI numbers are grouped into categories meant to reflect the degree of risk a person faces. Those people with the lowest risks of disease seem to fall in the 18.5 to 24.9 BMI range and are considered to be “normal”. A BMI of 25 seems to be the threshold where disease risk significantly increases and a BMI of 30 confers even greater health risks. These ranges have been separated into “overweight” and “obese” categories.

BMI Categories:

• Underweight = <18.5
• Normal weight = 18.5-24.9
• Overweight = 25-29.9
• Obesity = BMI of 30 or greater
