BMI Formula
BMI = weight (kg) / height (m)²
BMI is a screening tool, not a diagnostic measure. Consult a healthcare professional for personalized advice.
What is BMI? Understanding Body Mass Index
Body Mass Index (BMI) is a simple calculation using your height and weight to estimate body fat. It's widely used by healthcare professionals as a quick screening tool to categorize individuals into weight categories: underweight, normal weight, overweight, and obese.
Our free BMI calculator for men and women uses the standard BMI formula recommended by the World Health Organization (WHO). Simply enter your height, weight, and gender to get your BMI score instantly.
BMI Differences Between Men and Women
While the BMI formula is the same for both genders, interpretation can differ. Women naturally have a higher body fat percentage than men at the same BMI. Men tend to carry more muscle mass, which means a man with a BMI of 26 may have less body fat than a woman with the same BMI. This is why our calculator provides gender-specific health tips.
Limitations of BMI
BMI doesn't distinguish between muscle and fat mass. Athletes and muscular individuals may have a high BMI without excess body fat. For a more complete picture of your health, consider combining BMI with waist circumference, body fat percentage, and consultation with a healthcare provider.
