About BMI Calculator
Body Mass Index is a quick way to gauge whether your weight falls in a healthy range for your height. A BMI calculator works it out in seconds: enter your height and weight, and it returns your BMI number along with the range it falls into and a healthy weight estimate.
The tool does the formula for you and shows where you sit, all in your browser. It is free, instant, and needs no signup. Use it as a general wellness check, a starting point for fitness goals, or a reference when talking with a health professional.
