BMI Calculator — Calculate Your Body Mass Index
Determine your Body Mass Index (BMI) instantly. Input your weight and height to get a quick evaluation of your body weight classification.
A Body Mass Index (BMI) is a simple, internationally recognized calculation used to estimate total body fat based on your height and weight. Calculating your BMI is the first step in identifying whether you fall into an underweight, healthy, overweight, or obese category. It is widely used by doctors and healthcare providers globally as an essential screening tool for prospective health risks. Maintaining a healthy BMI is critical because it significantly lowers your risk of developing severe, life-altering conditions like Type-2 Diabetes, Hypertension (High Blood Pressure), and Coronary Artery Disease. Use our clinical-grade tool below to instantly check your current health status and take the first step toward a healthier lifestyle.

What Your Result Means
Standard international BMI ranges are defined by the World Health Organization (WHO), but clinical research shows that Indian adults are more susceptible to cardiovascular disease and diabetes at lower BMIs. Therefore, the Indian Consensus BMI ranges are slightly stricter:
| Category | Indian BMI Range | What It Means For You |
|---|---|---|
| Underweight | < 18.5 | You may be experiencing nutritional deficiencies. This can lead to a weakened immune system, osteoporosis, and chronic fatigue. |
| Normal / Healthy | 18.5 – 22.9 | Excellent! You are at a low risk for metabolic syndromes. Maintain this with a balanced diet and regular exercise. |
| Overweight | 23.0 – 24.9 | You are at moderate risk for developing diabetes and hypertension. A proactive approach to diet and fitness is highly recommended. |
| Obese | ≥ 25.0 | You are at a high to extreme risk for chronic heart conditions, severe joint pain, and sleep apnea. Medical intervention may be required. |
When to See a Doctor
If your BMI falls into the Overweight or Obese category, or if you have experienced sudden, unexplained weight loss dropping you into the Underweight category, it is time to consult a healthcare professional. High BMI is a direct precursor to life-threatening conditions such as Coronary Artery Disease, Type-2 Diabetes, and severe osteoarthritis.
