What is Body Mass Index (BMI)?
BMI is a widely used health screening tool that estimates body fat based on your height and weight. Healthcare professionals use BMI to assess risk for conditions like heart disease, diabetes, and obesity.
Why it matters:
BMI is a widely-used screening tool in healthcare to assess whether you’re underweight, at a healthy weight, overweight, or obese. While it’s not a diagnostic tool, it gives you a quick snapshot of your overall weight health—and can help you start important conversations about your fitness, nutrition, and wellness goals.
Benefits of using this tool:
- Instant Results: Get your BMI in seconds.
- Simple: No sign-ups or downloads required.
- Health Awareness: Understand your weight category (underweight, normal, overweight, obese).
Whether you’re starting a new diet, fitness routine, or simply want to stay informed about your health, our free BMI calculator provides a quick and easy way to measure your body composition.
