Frequently asked questions

Why a range instead of one number?
No single weight is "ideal" for everyone of a given height. Build, muscle and frame vary, so a healthy range is more useful and realistic than one figure.
Which formula does it use?
It shows the Devine formula target alongside the weight range for a healthy BMI (18.5–24.9), so you can see both perspectives.
Is this medical advice?
No. These calculators are for general information and education only. They are not a diagnosis or a substitute for professional care — talk to a doctor or qualified clinician about your health.
