Body mass index (BMI) calculator

About this Calculator

The Body Mass Index (BMI) calculator is a widely used tool for assessing body weight relative to height. It provides a simple numerical measure that helps categorize individuals into different weight status categories, such as underweight, normal weight, overweight, and various classes of obesity. This calculator is a valuable resource for both clinicians and individuals to evaluate health risks associated with body weight.

BMI Categories:

  • Below normal weight: BMI less than 18.5
  • Normal weight: BMI 18.5–24.9
  • Overweight: BMI 25–29.9
  • Class I Obesity: BMI 30–34.9
  • Class II Obesity: BMI 35–39.9
  • Class III Obesity: BMI 40 or greater

While BMI is a useful screening tool, it does not directly measure body fat or account for muscle mass, bone density, and overall body composition. Therefore, it should be used in conjunction with other assessments for a comprehensive evaluation of an individual's health.

BMI = Weight (kg) Height (m)2
