BMI Calculator by Age and Gender
Smart BMI was developed specifically for this website. It adds age and sex to conventional BMI to give a more differentiated interpretation of your body weight.
Over twelve years of Smart BMI: developed further together →Important limitations
BMI and SBMI are not diagnoses or individual risk predictions. Pregnancy, growth, high muscle mass and illness can affect interpretation. Seek qualified advice if you are concerned.
Sources and limitations →Why enter age and gender?
The BMI formula itself uses height and weight only. Smart BMI uses age and the sex selected for calculation to place that BMI within its own reference model. It does not measure body fat, muscle or individual health. Enter your current height, weight and exact age for your own result.
