Calculate your Body Mass Index and understand what it means for your health
Calculate your Body Mass Index and health status
Our free BMI calculator helps you determine your Body Mass Index (BMI) and understand what it means for your health. BMI is a simple measure that uses your height and weight to work out if your weight is healthy.
Body Mass Index (BMI) is a number calculated from your weight and height. It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.
While BMI is a useful screening tool, it doesn't measure body fat directly or account for factors like muscle mass, bone density, age, sex, and ethnicity. For a complete health assessment, consult with a healthcare professional.
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.
BMI = Weight (kg) ÷ Height (m)²
