FAQ

BMI of 11 — is it good or bad?

BMI 11 for Males and Females means Underweight/Severe thinness

Is BMI of 11 dangerous?

BMI of 11 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 11?

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 11 means about 70.1 lb (31.8 kg). A taller person reaches the same BMI at a proportionally higher weight.

Does a BMI of 11 mean the same for men and women?

Yes — the WHO adult scale has no separate cut-offs by sex, so a BMI of 11 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.
