Use this BMI calculator to estimate your body mass index from your height and weight. BMI is a common screening tool used to classify weight status into broad categories such as underweight, normal weight, overweight and obesity. This page also shows an estimated healthy weight range for your height, which can be useful for general awareness, fitness tracking and health-related forms.
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat mass. Athletes may show high BMI despite being healthy. Always consult a healthcare professional for a full assessment.
No. BMI is a screening indicator, not a diagnosis. It can help flag a possible issue, but medical assessment usually considers other factors such as age, body composition, waist size and overall health.
Formula: BMI = Weight (kg) / Height² (m) | Underweight: <18.5 | Normal: 18.5–24.9 | Overweight: 25–29.9 | Obese: ≥30
Example: Weight 70 kg, Height 175 cm → BMI = 70 / 1.75² = 22.9 → Normal weight. Ideal range: 56.7–76.3 kg.
