Calculate your Body Mass Index (BMI) and assess whether you're in a healthy weight range. Our BMI calculator provides personalized recommendations and health insights based on your measurements.
Understanding Body Mass Index (BMI)
BMI is a widely used screening tool that estimates body fat based on height and weight. While not perfect, it provides a quick assessment of whether you're in a healthy weight range.
BMI Categories
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5-24.9
- Overweight: BMI 25-29.9
- Obese Class I: BMI 30-34.9
- Obese Class II: BMI 35-39.9
- Obese Class III: BMI 40 and above
BMI Limitations
BMI doesn't distinguish between muscle and fat mass, so it may not be accurate for:
- Athletes with high muscle mass
- Elderly people who may have lost muscle mass
- Children and adolescents (use pediatric BMI charts)
- Pregnant or breastfeeding women
Health Implications
Healthy Weight Benefits: Lower risk of heart disease, diabetes, high blood pressure, and certain cancers.
Underweight Risks: May indicate malnutrition, eating disorders, or other health issues.
Overweight/Obesity Risks: Increased risk of cardiovascular disease, type 2 diabetes, sleep apnea, and joint problems.
Beyond BMI: Other Health Indicators
- Waist circumference (abdominal obesity indicator)
- Body fat percentage
- Muscle mass and bone density
- Overall fitness and cardiovascular health
- Blood pressure, cholesterol, and blood sugar levels
