BMI Calculator
Calculate body mass index from your weight and height.
How To Use This BMI Calculator
Enter your weight in kilograms and your height in centimeters, then calculate your BMI. The result gives a quick screening value based on your body size and places you in a standard BMI category.
BMI is commonly used for adults because it is simple and fast. It does not directly measure body fat, but it can be useful as a first check before looking at waist size, body fat percentage, or other measures.
Normal BMI Values
For most adults, a BMI from 18.5 to 24.9 is considered within the normal range. A BMI below 18.5 is underweight, 25.0 to 29.9 is overweight, and 30 or more is obesity.
That said, BMI has limits. It can overestimate body fat in muscular people and may not reflect fat distribution. For a broader picture, compare your result with the Body Fat Calculator and Waist-To-Hip Ratio Calculator.
