BMI is a screening tool and does not measure body fat or diagnose health.

Understanding your BMI result

Body mass index is calculated from height and weight. It is often used as a quick, broad screening measure because it is easy to calculate, but it cannot describe every part of a person's health. Treat this result as one reference point rather than a diagnosis.

Healthy weight range

The range shown here uses standard adult BMI cutoffs for your entered height. It does not account for body composition, medical history, or personal circumstances. A healthcare professional can help put a BMI result into the right context.

A calm, practical next step

If you have a health concern, focus on sustainable habits and ask a qualified clinician for personalized guidance. Avoid making decisions based only on a calculator result, especially for children, pregnancy, athletes, or older adults.

Frequently asked questions

A few quick answers before you go.

What does BMI measure?

BMI compares weight with height. It is a useful population screening measure, but it does not directly measure body fat or overall health.

Can BMI be inaccurate?

Yes. Muscle mass, pregnancy, age, ethnicity, and other factors can affect how well BMI represents an individual.
