Frequently asked questions

Is this healthy weight range the same for men and women?

Yes, the BMI-based healthy weight range is the same for adult men and women. However, body composition differences mean that BMI may not be equally accurate for all individuals; for example, men often have more muscle mass, which can elevate BMI.

What if I am very muscular?

BMI does not differentiate between muscle and fat. If you have a high muscle mass, your BMI may be in the overweight or obese range even if your body fat percentage is low. In such cases, consider body composition measurements or waist circumference for a more accurate health assessment.

Is this calculator suitable for children or teenagers?

No, this calculator is intended for adults (age 20 and older). For children and teens (ages 2–20), BMI-for-age percentiles are used, which are age- and sex-specific. Consult a pediatrician or use a growth chart for accurate assessment.
