Ideal Weight Calculator
Discover your ideal body weight based on multiple scientific formulas (Robinson, Miller, Devine, Hamwi) and your healthy BMI range.
Note: Formulas only apply to heights 5 feet (152.4 cm) and above.
Please enter a height of at least 5 feet (153 cm) to see your ideal weight estimates.
The Science of Ideal Weight
"Ideal weight" is a subjective term, but medical science has developed several formulas over the decades to estimate a healthy weight range based strictly on height and gender. Our calculator computes your ideal weight using the four most prominent clinical formulas simultaneously.
The Four Formulas
- J.D. Robinson (1983): The most widely used formula in modern medical institutions. It slightly modifies older models to reflect healthier baseline weights.
- D.R. Miller (1983): A secondary prominent formula that typically yields a slightly lower, more conservative weight range.
- G.J. Hamwi (1964): The original clinical formula, often used as a baseline reference for calculating drug dosages in clinical settings.
- B.J. Devine (1974): Widely used for determining pharmacokinetic drug clearances in obese patients.
