About Our BMI Calculator
Our free BMI calculator helps you understand your body mass index and provides insights into your healthy weight range. Body Mass Index (BMI) is a widely used screening tool that relates your weight to your height. While BMI has limitations and doesn't measure body fat directly, it's a useful starting point for assessing weight-related health risks and understanding whether you're in a healthy weight range.
What is Body Mass Index (BMI)?
BMI is calculated by dividing your weight by the square of your height. The result places you in one of several categories: underweight, normal weight, overweight, or obese. These categories help healthcare professionals assess potential weight-related health risks. However, it's important to note that BMI doesn't distinguish between muscle and fat mass, so athletes or very muscular individuals may have a high BMI despite having low body fat.

Limitations of BMI
While BMI is a useful screening tool, it has several limitations:
- •Doesn't distinguish between muscle and fat mass
- •May not be accurate for athletes, bodybuilders, or very muscular individuals
- •Doesn't account for age, sex, ethnicity, or bone density
- •Not suitable for pregnant or breastfeeding women
- •Should be used alongside other health assessments
Always consult with healthcare professionals for a comprehensive health evaluation that considers your unique circumstances, body composition, and overall health status.
