Body measurements
BMI calculator
Calculate your body mass index using height and weight, and understand the limits of this adult screening measure.
Your starting point
Let’s work it out.
For adults aged 18 and over. Do not use these ranges during pregnancy or for children. BMI can be less useful for older adults, muscular people and some ethnic backgrounds.

Does a BMI result diagnose a health problem?
No. A result is a screening measure, not a diagnosis or a target weight. If you are concerned about your weight or a change in it, speak with your usual health professional.
