Ideal Weight Calculator
Estimate a healthy weight range for your height using the Devine formula and the BMI healthy band.
Quick guide
Choose your sex and enter your height. You get a single reference weight from the Devine formula and a healthy weight range from the BMI band; frame size and muscle mass can shift what is right for you.
Read the full explanationHow It Works
“Ideal weight” formulas like Devine give a single reference point from height and sex, while the BMI healthy band gives a range. Frame size and muscle mass shift what is truly ideal for you.
Formula Used
Devine: men 50 kg + 2.3 kg per inch over 5 ft; women 45.5 kg + 2.3 kg per inch over 5 ft.
Example Calculation
At 170 cm, the Devine estimate is about 66 kg for a man, with a healthy BMI range of roughly 53.5–72 kg.
Practical Use Cases
- Set a realistic goal weight range.
- Cross-check a single-formula estimate against the BMI band.
- Support conversations with a healthcare professional.
