Enter your height and weight to instantly calculate your BMI, see your category, and find your healthy weight range.
Body Mass Index (BMI) is a simple screening metric that uses your height and weight to estimate body fat. It is calculated by dividing your weight in kilograms by the square of your height in meters. While BMI does not measure body fat directly, it correlates with more direct measures of body fat and is widely used by healthcare professionals as a first-pass assessment.
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
BMI does not distinguish between muscle mass and fat mass, so athletes with significant muscle may register as overweight despite having low body fat. It also does not account for bone density, age, gender, or fat distribution. For a more complete picture, consider combining BMI with waist circumference, body fat percentage, and other health indicators.
Despite these limitations, BMI remains one of the most accessible and widely studied tools for assessing weight-related health risks across large populations. It serves as an excellent starting point for conversations with your healthcare provider about weight management.
