Body Mass Index, or BMI, uses height and weight to estimate a general adult weight-status category. It is often used as a quick screening tool, not as a full measure of health or body fat.
BMI = weight (kg) ÷ height (m²)

|---|---|
| Less than 18.5 | Underweight |
| 18.5 - 24.9 | Normal weight |
| 25.0 - 29.9 | Overweight |

Body Mass Index, or BMI, uses your weight and height to estimate a general adult weight-status category. The calculator converts your height into meters, squares that value, and divides your weight in kilograms by the result.
BMI = weight (kg) / height (m²)
The result is then matched to the common adult BMI ranges so you can see whether it falls into underweight, normal weight, overweight, or obese. The page also estimates a general healthy-weight range for your height to add more context.
| BMI Range | Category |
|---|---|
| Less than 18.5 | Underweight |
| 18.5 - 24.9 | Normal weight |
| 25.0 - 29.9 | Overweight |
| 30.0 or higher | Obese |

This page is useful when you want more than a raw BMI number. It gives you the score, a general adult category, and a rough healthy-weight range for your height, so the result is easier to understand at a glance.
That makes it helpful for basic awareness, fitness tracking, and simple check-ins over time. You can quickly see whether a weight change is moving you closer to or farther from the general adult normal range.
It also works well as a starting point. Many people use BMI as a simple first look before thinking about progress goals, percentage changes, or broader health questions.
BMI is most useful when you want a fast, general screening measure based on height and weight. It can help with personal check-ins, fitness progress reviews, and everyday awareness when you want a rough category without doing the math yourself.
BMI does not directly measure body fat, muscle mass, fitness level, or overall health. Two people can have the same BMI and still have very different body composition. That is why this tool is best used as general guidance, not as a diagnosis.
People use this page to calculate BMI, check BMI by height and weight, find a healthy weight range, and understand adult BMI categories. Keeping those practical use cases together helps both users and search engines understand what the page solves.
Enter your weight in kilograms and your height in centimeters, then click Calculate BMI. The result gives your BMI value, a general adult category, and a rough healthy-weight range for the height you entered.
Use the result as a quick awareness tool or progress check, then move into related calculators if you want to compare changes, track time, or continue with other planning tasks.
