BMI Limitations:
BMI is a useful screening tool, but it has several limitations:
- Doesn't distinguish between fat, muscle, or bone mass
- May overestimate body fat in athletes and muscular individuals
- May underestimate body fat in older adults who have lost muscle mass
- Doesn't account for differences between ethnic groups
- Doesn't consider where fat is distributed in the body
For a more complete assessment, consult with a healthcare professional.
Note: This calculator is for adults 20 years and older. BMI for children and teens is calculated differently. The BMI formula is weight (kg) / [height (m)]².

BMI Formula
BMI = weight (kg) / [height (m)]²
Or in imperial units:
BMI = [weight (lb) / height² (in)] × 703
BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women.
While BMI is an useful screening tool, it is not a diagnostic of body fatness or health. A healthcare provider can help you interpret your BMI and evaluate your overall health.
