How It Works
The Devine formula
Ideal weight starts from a base value for someone 5 feet tall, then adds a fixed amount for every inch above that — the base and per-inch amount differ slightly between men and women.
A reference point, not a target
This formula was originally developed for medical dosing calculations, not as a personal fitness goal — it doesn't account for muscle mass, frame size, or individual body composition.
Example Calculation
A man who is 175cm (about 5'9") tall has an estimated ideal weight of around 71kg using the Devine formula.
Common Mistakes
- Treating the result as a strict target rather than a rough reference point — healthy weight varies by frame size, muscle mass, and individual factors.
- Using it for children or teens, since it's calibrated for adult body proportions.
- Ignoring that muscular or larger-framed individuals may naturally and healthily weigh more than this estimate.
Frequently Asked Questions
- Is the Devine formula the only 'ideal weight' formula?
- No — other formulas like Robinson, Miller, and Hamwi exist and give slightly different results. The Devine formula is one of the most commonly referenced, especially in clinical settings.
- Should I use this as a weight loss goal?
- It's better used as a general reference point alongside other measures like BMI and body fat percentage, rather than as a strict personal target — consult a healthcare provider for individualized advice.
