Calculate Your Body Mass Index
Calculate your Body Mass Index (BMI) to assess whether your weight is in a healthy range for your height. Our BMI calculator provides instant results with health category classifications based on WHO standards.
Determine your BMI and understand your weight category according to standard BMI classifications.
Body Mass Index (BMI) is a numerical value of your weight in relation to your height. It is used as a simple method to assess whether a person is underweight, normal weight, overweight, or obese.
| BMI Range | Weight Category |
|---|---|
| Less than 18.5 | Underweight |
| 18.5 - 24.9 | Normal weight |
| 25 - 29.9 | Overweight |
| 30 or more | Obesity |
While BMI is a useful screening tool, it does not directly measure body fat or account for muscle mass, bone density, overall body composition, and racial and sex differences. Always consult with a healthcare provider for a comprehensive health assessment.
By understanding your BMI and maintaining a healthy lifestyle, you can improve your overall well-being.
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is weight in kilograms and m² is height in meters squared. BMI categories: Underweight (< 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), Obese (≥ 30).
While BMI is a useful screening tool, it has limitations: it doesn't distinguish between muscle and fat mass, doesn't account for age, sex, or ethnicity differences, and may not accurately reflect health for athletes, elderly, or children. Consider BMI as one of several health indicators.
BMI correlates with various health risks. Higher BMI is associated with increased risk of: heart disease, type 2 diabetes, high blood pressure, certain cancers, and sleep apnea. Lower BMI may indicate malnutrition or other health concerns. Consult healthcare professionals for personalized health assessment.
