Calculate your BMI

What your BMI can and cannot tell you

BMI compares weight with height and is commonly used as a general screening tool. It does not measure body fat directly and does not account for muscle mass, body composition, medical history, pregnancy, or many other individual factors.

BMI rangeGeneral category
Below 18.5Underweight
18.5–24.9Normal weight
25.0–29.9Overweight
30.0 and aboveObesity
Important: BMI is not a diagnosis. If you have questions about weight, health risks, or treatment options, speak with a qualified healthcare professional.

BMI Calculator FAQ

Is BMI enough to decide if a program is right for me?

No. BMI is only one screening tool. A licensed healthcare provider may consider BMI, medical history, medications, health goals, and other factors.

Does a high BMI mean I qualify for medication?

Not necessarily. Eligibility depends on a provider evaluation and applicable medical guidelines. This website cannot determine eligibility.

Can athletes have a high BMI?

Yes. BMI does not distinguish between muscle and fat, so it can be less useful for some athletes and highly muscular individuals.
