    FAQ

    BMI of 13 — is it good or bad?

    BMI 13 for Males and Females means Underweight/Severe thinness

    Is BMI of 13 dangerous?

    BMI of 13 falls into the "Underweight/Severe thinness" category. A BMI below 18.5 may indicate insufficient body weight. Consult a healthcare professional for personalized advice.

    What weight gives a BMI of 13?

    BMI is weight divided by height in metres squared, so it names a weight only once the height is fixed: at 170 cm (5 ft 7 in) a BMI of 13 means about 82.9 lb (37.6 kg). A taller person reaches the same BMI at a proportionally higher weight.

    Does a BMI of 13 mean the same for men and women?

    Yes — the WHO adult scale has no separate cut-offs by sex, so a BMI of 13 reads as "Underweight/Severe thinness" for both. Age is what changes it: the adult table starts at 18, while children and teenagers aged 5–19 are compared with age- and sex-specific reference values instead.
