BMI Calculator: Understand Your Body Mass Index and Health
Use a BMI calculator to find your body mass index and understand what it means for your health (informational only, not medical advice).
What is BMI?
Body Mass Index (BMI) is a screening tool for weight categories that may indicate health risks. It is calculated as weight (kg) divided by height (m²). BMI categories are underweight, normal weight, overweight, and obese.
BMI categories explained
BMI under 18.5 is underweight, 18.5-24.9 is normal weight, 25-29.9 is overweight, and 30+ is obese. These are screening ranges; BMI does not directly measure body fat or account for muscle mass.
How to use the BMI calculator
Enter your weight and height. The calculator instantly shows your BMI and category. Remember: BMI is one health screening tool among many. Consult healthcare providers for personalized health advice.
Understanding your results
A healthy BMI is a starting point for wellness planning. Factors like muscle mass, age, metabolism, and overall fitness also matter. Use BMI results alongside other health metrics and professional guidance.
