    FAQ

    BMI of 18 — is it good or bad?

    BMI 18 for Males and Females means Underweight/Mild thinness

    Is BMI of 18 dangerous?

    BMI of 18 falls into the "Underweight/Mild 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 18?

    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 18 means about 114.7 lb (52 kg). A taller person reaches the same BMI at a proportionally higher weight.

    Does a BMI of 18 mean the same for men and women?

    Yes — the WHO adult scale has no separate cut-offs by sex, so a BMI of 18 reads as "Underweight/Mild thinness" 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.
