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.
