BMI Calculator for Women and Men

Body Mass Index (BMI) is a simple index of weight for height which is widely used to categorize underweight, overweight and obesity. BMI is bodyweight (kg) divided by height (m) squared (BMI = 70 kg / (1.75 m2) = 70 / 3.06 = 22.9). Overweight is typically defined as a BMI of 25 to 29.9, and obesity is defined as a BMI of 30 or more, and severe obesity is defined as a BMI of 40 or more.

Body Mass Index can be calculated with the BMI calculator easily as well as without the need of costly devices. Having said that, BMI categories don’t take into consideration several factors like frame size and muscle mass, and although BMI can be used for most men and women, it does have some limitations:

  • It might overestimate body fat in sports people as well as people that have a muscular build.
  • It might underestimate body fat in elderly people as well as people that have lost muscle.

In spite of this, BMI categories are frequently considered to be an adequate tool for determining if sedentary people are underweight, overweight or obese. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher a person’s BMI, the higher the risk for a number of diseases like high blood pressure, heart disease, type 2 diabetes, breathing problems, gallstones, and certain cancers.

The Infographic below the BMI calculator demonstrates quite clearly how body mass index is associated with risk of death.
