Ideal Weight Calculator: A Practical Way to Compare Healthy Weight References
The Ideal Weight Calculator on Dxcalculator.com provides an objective reference for how height and gender relate to common ideal body weight estimates[cite: 2]. Rather than prescribing an inflexible target, this tool displays multiple formulas side by side with a standard healthy BMI weight range to give you comprehensive context.
The Four Ideal Weight Formulas
Robinson Formula (1983)
A modernized modification of Devine's earlier work based on population weight statistics.
Miller Formula (1983)
Proposes lower increments per inch of height above 5 feet compared to Robinson and Devine.
Devine Formula (1974)
Originally designed for standardized clinical drug dosing calculations, it remains the most commonly cited formula.
Hamwi Formula (1964)
A classic rule-of-thumb system frequently used by dietitians and nutritionists.
