Calculate your Body Mass Index and health category
Calculate your Body Mass Index (BMI) instantly with our easy-to-use BMI Calculator. BMI is a widely used screening tool that helps assess whether your weight is within a healthy range for your height. This calculator supports both metric (kilograms and centimeters) and imperial (pounds and feet/inches) measurements, making it accessible to users worldwide. Simply enter your weight and height to receive your BMI score along with your health category classification (Underweight, Normal weight, Overweight, or Obese) based on WHO standards. The tool provides color-coded results and personalized health advice to help you understand your BMI score. While BMI is a useful screening tool, it's important to note that it doesn't measure body fat directly and may not be accurate for athletes with high muscle mass, pregnant women, or elderly individuals. Always consult healthcare professionals for personalized health guidance and to discuss your specific health goals.
BMI (Body Mass Index) is a numerical value derived from your height and weight. It's used as a screening tool to categorize individuals into weight status categories: underweight, normal weight, overweight, and obese. While not a diagnostic tool, it helps identify potential health risks associated with weight.
According to WHO standards, a healthy BMI range for adults is 18.5 to 24.9. BMI below 18.5 is considered underweight, 25.0 to 29.9 is overweight, and 30.0 or higher is classified as obese.
BMI is a useful screening tool for most adults, but it has limitations. It may not be accurate for athletes with high muscle mass, pregnant or nursing women, elderly individuals with reduced muscle mass, or children and teenagers (who require age and sex-specific BMI percentiles). It also doesn't distinguish between muscle and fat mass.
If your BMI is outside the normal range, it's advisable to consult with a healthcare provider. They can perform additional assessments like body composition analysis, waist circumference measurements, and other health screenings to give you a complete picture of your health status.
For general health monitoring, checking your BMI monthly or quarterly is sufficient. If you're actively working on weight management goals, you might check it weekly, though remember that sustainable weight changes happen gradually over time.
