What is BMI (Body Mass Index)?
BMI stands for Body Mass Index. It’s a widely used health indicator that estimates your body fat based on height and weight. Doctors and health experts use it globally to classify whether a person is underweight, normal, overweight, or obese.
It’s not a perfect measure, but it’s a helpful starting point if you're trying to understand your weight status and overall wellness.
🔢 How is BMI Calculated?
The BMI formula is quite simple and uses your height and weight in metric units:
BMI = weight (kg) ÷ [height (m)]²
For example, if you weigh 68 kg and are 170 cm tall:
BMI = 68 ÷ (1.7 x 1.7) = 23.5 → That’s a “Normal” BMI.

- Understand if your weight is healthy or not
- Track progress in your fitness or weight loss plan

- Set realistic and safe weight goals
Whether you’re trying to gain weight, lose it, or maintain where you are — BMI is a great reference point to begin with.
⚠️ Limitations of BMI
It’s important to know that BMI doesn’t measure body fat directly. For example, athletes or muscular individuals might show a high BMI even if they’re very fit. Similarly, someone with low muscle mass might show a “normal” BMI but still have excess body fat.
That’s why BMI should be used as a general guide — not a final diagnosis. For more precise measurements, you can check your body fat percentage, waist-to-hip ratio, or use our BMR Calculator to estimate your daily calorie needs.
