Curious to know if your weight is healthy for your height? You’re not alone. Every day, millions of people try to find out if their weight is in the right range—and the Body Mass Index (BMI) makes it easy. Our free online BMI Calculator is here to help you get answers instantly. Just enter your weight and height, and the tool will tell you whether you're underweight, normal, overweight, or obese.
BMI, or Body Mass Index, is a simple number that compares your weight to your height. It’s not a perfect tool, but it gives a good general idea of whether your weight is in a healthy range. Doctors, nutritionists, and fitness coaches use it as a starting point to assess your overall health. BMI doesn’t measure fat directly, but it does highlight potential health risks linked to being underweight or overweight.
Formula: BMI = weight (kg) ÷ [height (m) × height (m)]
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 - 24.9 | Normal weight |
| 25 - 29.9 | Overweight |
| 30 and above | Obese |
Let’s say your weight is 70 kg and your height is 1.75 meters:
BMI = 70 ÷ (1.75 × 1.75) = 22.86
That means you fall into the "Normal weight" category. Easy, right?
