What Is BMI?
BMI, or Body Mass Index, is a simple measurement used to estimate whether your weight is appropriate for your height. It can be a useful starting point for understanding your general weight category.
How Does a BMI Calculator Work?
A BMI calculator uses your height and weight to calculate your BMI.
BMI = Weight (kg) ÷ Height (m)²

BMI Categories
For adults, BMI is generally grouped into these categories:
- Underweight: Below 18.5
- Healthy weight: 18.5–24.9
- Overweight: 25–29.9
- Obesity: 30 or higher
These ranges are general guidelines and may not accurately reflect body composition for everyone.
Why Use a BMI Calculator?
A BMI calculator can help you:
- Understand your current weight category
- Track changes in your weight over time
- Set realistic fitness goals
- Get a quick overview of your weight in relation to your height
Is BMI an accurate measure of health?
BMI is useful as a general screening tool, but it does not directly measure body fat or account for muscle mass, body composition, or many other factors that affect health.
How often should I calculate my BMI?
There is no need to calculate BMI every day. Checking it occasionally can help you monitor longer-term changes, especially when combined with other meaningful fitness and health measurements.
