Instantly calculate your Body Mass Index (BMI) with our easy-to-use tool. Get immediate insights into your weight status based on World Health Organization (WHO) guidelines and learn if you are in a healthy range.
Body Mass Index (BMI) is a simple yet effective screening tool used to estimate your body fat based on your height and weight. It provides a numerical value that helps determine whether you are underweight, in a healthy weight range, overweight, or obese. While it doesn't measure body fat directly, research has shown that BMI is moderately correlated with more direct measures of body fat and is a reliable indicator of various health risks. It is the standard metric used by health organizations like the WHO and CDC to assess weight status in populations.
The following table outlines the standard weight status categories associated with BMI ranges for adults:
| Weight Status | BMI Range |
|---|---|
| Underweight | Less than 18.5 |
| Normal / Healthy Weight | 18.5 – 24.9 |
| Overweight | 25.0 – 29.9 |
| Obesity (Class I) | 30.0 – 34.9 |
| Obesity (Class II) | 35.0 – 39.9 |
| Severe Obesity (Class III) | 40.0 or higher |
