Understanding the Body Mass Index (BMI) Calculator
Body Mass Index (BMI) is a measure that uses your height and weight to work out if your weight is in a healthy range. It is a simple, inexpensive, and noninvasive screening tool for identifying potential weight-related health issues in adults. Our calculator provides not just your BMI score, but also your healthy weight range, giving you actionable information.
Interpreting Your BMI Result: The BMI Chart
The standard adult BMI categories, as defined by the World Health Organization (WHO), are the same for both men and women:
- Below 18.5: Underweight
- 18.5 – 24.9: Healthy Weight
- 25.0 – 29.9: Overweight
- 30.0 and Above: Obesity
Beyond the Number: Actionable Steps
Your BMI score is a starting point, not a final judgment. It can empower you to make healthy lifestyle changes. Focus on sustainable habits rather than just the number on the scale:
- Balanced Nutrition: Emphasize whole foods like fruits, vegetables, lean proteins, and whole grains. Understanding your calorie needs with our TDEE Calculator can be a great first step.
- Regular Physical Activity: Aim for a combination of cardiovascular exercise (like walking, running, or cycling) and strength training.
- Body Composition: Remember that BMI doesn't distinguish between muscle and fat. For a more complete picture, consider using this tool with our Body Fat Calculator.
Limitations of the BMI Scale
While BMI is a very useful general indicator, it is important to understand its limitations. Very muscular individuals, for example, may have a high BMI due to the weight of their muscle mass, not excess fat. Always use this tool as part of a broader conversation with a healthcare provider.
