BMI (Body Mass Index) is a widely used measure that estimates body fat based on height and weight. It helps classify individuals as underweight, normal weight, overweight, or obese, providing a quick health screening metric.
Calculate your BMI in seconds to get a basic understanding of whether your current weight is in a healthy range for your height.
Use BMI as one of several metrics to monitor changes in your body composition as you progress through a fitness or weight management program.
Healthcare providers use BMI to screen patients for potential weight-related health risks โ though it's always used alongside other clinical measures.
BMI under 18.5 is underweight, 18.5โ24.9 is normal, 25โ29.9 is overweight, and 30+ is obese โ according to WHO classification standards.
BMI is calculated by dividing weight in kilograms by the square of height in meters (kg/mยฒ). While BMI is a useful screening tool, it does not directly measure body fat and may not accurately reflect health for athletes, elderly individuals, or those with high muscle mass. Always consult a healthcare professional for a complete health assessment.
