Calculate Your BMI
Calculate your Body Mass Index (BMI) with our free online calculator. Enter your height and weight to find out if you are in the underweight, normal, overweight, or obese range. BMI is a widely used screening tool that provides a general indication of whether your weight is in a healthy range for your height.
BMI is calculated by dividing your weight in kilograms by your height in meters squared. While it does not directly measure body fat, it is a useful starting point for understanding your weight status. Our calculator supports both metric and imperial units.
Understanding Your Results
A BMI under 18.5 is considered underweight, 18.5 to 24.9 is normal, 25 to 29.9 is overweight, and 30 or above is obese. Remember that BMI is a general guideline and does not account for muscle mass, bone density, or body composition. Consult a healthcare professional for personalized advice.
