Formula
Devine formula: 50 kg (men) or 45.5 kg (women) + 2.3 kg per inch over 5 feet
The Devine formula is the reference weight formula most widely used in clinical medicine (for example, to calculate medication dosing). It's validated for adult heights of 5 feet (152 cm) and up.
Example
A man who is 5'10" (178 cm) tall has an ideal weight of about 73 kg.
Frequently Asked Questions
Should I try to weigh exactly this number?
No — this is a general reference point, originally developed for medication dosing calculations, not a personal health goal. A healthy weight range varies by individual.
Why does sex change the result?
The formula uses a different baseline for men and women (50 kg vs. 45.5 kg) to reflect average differences in body composition.
