The Body Mass Index (BMI) calculator is an internationally recognized health screening tool established by the World Health Organization (WHO). It evaluates your body mass relative to your height, helping classify whether you are underweight, normal weight, overweight, or obese.
BMI provides a valuable baseline metric for adults to gauge general health risk categories associated with excess body fat, such as cardiovascular disease, hypertension, and type 2 diabetes.
Our calculator supports both Metric (centimeters & kilograms) and Imperial (feet, inches & pounds) measurement systems, accompanied by a visual classification breakdown and ideal weight range recommendations.
Follow these simple steps to achieve perfect results in seconds.
Choose between Metric (cm / kg) or Imperial (feet / inches / lbs).

Instantly view your calculated BMI score, health classification, and healthy weight target range.
