What is Body Mass Index (BMI)?
BMI or Body Mass Index is a measurement that helps to determine how fat you are with regards to your weight and height. It is the formula simple to calculate:
BMI = kg / m² (weight in kilograms divided by height in meters squared)
BMI = (weight in pounds / inches²) × 703
Is this outdated? Not quite. All over the world, BMI remains a fast and useful tool for health screening. It’s used by doctors in the U.S., clinics in India, and nutritionists in the UK.
What is the Reason to Use a BMI Calculator in the Year 2025?
Remote work, sedentary lifestyles, fast food—our routines have changed. A BMI calculator in 2025 is more than a number—it’s an alarm.
- Self awareness: Know your baseline before starting a gym or diet.
- Health monitoring: Spot weight changes early.
- Preventive care: Early detection of weight-related issues.
What do the BMI Categories Mean?
| Range of BMI | Category |
|---|---|
| Less than 18.5 | Underweight |
| 18.5 - 24.9 | Normal |
| 25.0 - 29.9 | Overweight |
| 30.0 and over | Obese |
Note: These apply to adults 18 years and older. Children and teens are interpreted differently.
BMI is not perfect—it doesn’t account for muscle mass or bone density—but it’s still a great starting point for most people.

Human Factor: BMI is Not Enough?
Consider Rishi, a 29-year-old software engineer in Delhi. His BMI was 27 (overweight), but he had visible abs from daily workouts. BMI doesn't distinguish muscle from fat.
It also doesn’t account for age, gender, or bone density. So no—it’s not perfect. But it’s still useful.
Think of BMI like a fuel gauge: it shows when something might be wrong, but it doesn’t replace the mechanic.
Children and Teenager BMI
For children and teens, BMI is interpreted using percentiles based on age and gender.
For example, a 12-year-old girl in the 90th percentile may be overweight, but that could be normal based on her development. Always consult a pediatrician.
