Formula Insights
Devine Formula
The most commonly used formula in clinical settings.
Developed in 1974 for drug dosage calculations.
Robinson Formula
Focuses on providing a more moderate target for women.
A 1983 revision of the Devine formula.
Miller Formula
Preferred for taller individuals as it scales differently.
Introduced in 1983 together with Robinson's.
Hamwi Formula
A simple, widely-known calculation for general health.
One of the oldest formulas (1964) still in use.
Beyond Formulas
While these formulas provide baseline targets, modern healthcare emphasizes Body Composition. Muscle is denser than fat, and frame size varies greatly.
Always cross-reference with body fat % and waist-to-height ratio.
Health Reminder
"Ideal body weight should be viewed as a guide, not a strict rule. Your energy levels, strength, and overall wellness are far more critical indicators than a single number on a scale."
Science of Formulas
Historically, ideal body weight was developed to calculate clinical settings such as drug clearance and ventilator settings. These models consider your height as the primary driver of skeletal and organ mass.
Consolidated Approach
Rather than relying on a single formula, our calculator provides an average across the four major clinical formulas (Devine, Robinson, Miller, and Hamwi) to give you a more robust and balanced target.
