BMI Calculator With Limitations Explained

A simple BMI calculator that explains what the number can and cannot tell you.

Enter height and weight to estimate BMI.

How to use this estimate

Use BMI as one context clue. It can help start a conversation about weight and health, but it cannot tell you whether a specific plan is right for your body.

If you are pregnant, postpartum, highly muscular, under 18, medically complex, or distressed by weight numbers, use clinician guidance instead of a generic calculator.

FAQ

Is BMI a diagnosis?

No. BMI is a screening measure, not a diagnosis or complete assessment of health.

Can BMI be misleading?

Yes. It does not directly measure muscle, body fat distribution, pregnancy status, or medical history.

Should I set a weight-loss goal from BMI alone?

No. Use BMI with other context and professional guidance when needed.
