BMI Calculator
Calculate your Body Mass Index to assess if your weight is healthy
About this calculator
The BMI Calculator is a simple yet powerful tool that helps you determine your Body Mass Index by using your height and weight measurements. BMI is a widely recognized screening tool used by healthcare professionals to categorize weight status and assess potential health risks associated with being underweight, normal weight, overweight, or obese. This calculator provides instant results that can help you understand where you stand on the weight spectrum and whether you should consider lifestyle changes or consult with a healthcare provider about your weight management goals.
How to use
Simply enter your current weight and height into the designated fields, selecting the appropriate units (pounds/kilograms for weight, feet/inches or centimeters for height). Click the calculate button to instantly receive your BMI score along with the corresponding weight category classification (underweight, normal, overweight, or obese).
Frequently asked questions
What is a healthy BMI range?
A healthy BMI typically falls between 18.5 and 24.9. Below 18.5 is considered underweight, 25-29.9 is overweight, and 30+ is classified as obese.
Is BMI accurate for everyone?
BMI is a general screening tool but may not be accurate for athletes, elderly individuals, or those with high muscle mass, as it doesn't distinguish between muscle and fat.
How often should I check my BMI?
Checking your BMI monthly or quarterly is sufficient for most people, as significant weight changes typically occur over longer periods rather than daily fluctuations.
