Who this is for

Adults aged 20 or older, outside pregnancy.

How it works

Lower boundary = 18.5 × height(m)². Exclusive upper boundary = 25 × height(m)². This is the weight interval for adult BMI 18.5 to below 25; it is not a personalized target.

Keep in mind

Rounded boundary values are approximate; the upper boundary remains excluded.
Muscle, body composition and individual circumstances are not assessed.
