FAQ

BMI of 31 — is it good or bad?

BMI 31 for Males and Females means Obese/Class I

Is BMI of 31 dangerous?

BMI of 31 falls into the "Obese/Class I" category. A BMI above 24.9 may indicate excess body weight. Consult a healthcare professional for personalized advice.

What weight gives a BMI of 31?

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 31 means about 197.5 lb (89.6 kg). A taller person reaches the same BMI at a proportionally higher weight.

Does a BMI of 31 mean the same for men and women?

Yes — the WHO adult scale has no separate cut-offs by sex, so a BMI of 31 reads as "Obese/Class I" for both. Age is what changes it: the same table applies from 18 to 65, while children and teenagers are compared with age-and-sex percentiles instead.
