What is BMI?
The Body Mass Index (BMI) is a simple tool that relates your height to your weight. It is commonly used to assess whether a person's body weight falls within the typical range for their height—without the need for scales, measuring tape, or body scans.
Although the BMI is not an individual health assessment, it provides a useful starting point. It is particularly helpful for evaluating weight trends over time or comparing weight patterns across different population groups.
How BMI works
BMI is calculated by dividing body weight in kilograms by height in meters squared. The result is then classified into one of the following categories:
- Underweight
- Normal weight
- Overweight
Each category indicates how your weight relates to your height. The further the result deviates from “normal weight,” the more it may be worth examining additional health factors such as waist circumference, physical activity habits, or lifestyle.
Same system for everyone
The BMI formula is the same for men and women. It does not take muscle mass, fat distribution, or body composition into account, but it provides a stable reference value that is comparable across many people.
If your BMI is over 25, it may indicate that you fall outside the recommended range. This does not necessarily mean you are unhealthy, but it may be useful to review your eating habits, activity level, or seek medical advice—especially if the value increases over time.
Is BMI reliable?
BMI is a rough measurement. It describes the ratio of weight to height but does not indicate how that weight is composed—whether it is fat, muscle, or bone. People with high muscle mass, such as athletes, may appear “overweight” by BMI standards, even though they are fit.
What BMI is useful for, however, is providing guidance for concrete goals. If you want to regulate your weight, lowering your BMI by one or two points can be a realistic and trackable milestone.
BMI becomes even more meaningful when combined with other indicators—such as waist circumference or lifestyle information.
