Frequently Asked Questions
What is the Devine formula?▾
The Devine formula estimates ideal body weight for adults from height alone: 50 kg for men and 45.5 kg for women at 5 feet, plus 2.3 kg per inch above.
Does ideal weight vary with build or muscle mass?▾
Yes. Height-based formulas ignore frame size, age and muscle mass, so they are best used as a rough target rather than an exact prescription.
