FAQ

BMI of 39 — is it good or bad?

BMI 39 for Males and Females means Obese/Class II

Is BMI of 39 dangerous?

BMI of 39 falls into the "Obese/Class II" category. A BMI of 25 or more may indicate excess body weight. Consult a healthcare professional for personalized advice.

What weight gives a BMI of 39?

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 39 means about 248.5 lb (112.7 kg). A taller person reaches the same BMI at a proportionally higher weight.

Does a BMI of 39 mean the same for men and women?

Yes — the WHO adult scale has no separate cut-offs by sex, so a BMI of 39 reads as "Obese/Class II" 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.
