4-formula comparison: Devine, Miller, Robinson & Hamwi with BMI range
There is no single universally agreed definition of "ideal weight" — different clinical formulas developed over decades give different results depending on their intended use. This calculator computes your ideal weight using four established formulas (Devine, Miller, Robinson, and Hamwi) alongside the WHO BMI-based healthy range, letting you see where the consensus lies.
Frequently Asked Questions
Sobre Esta Calculadora
The four ideal weight formulas in this calculator were each developed for different clinical purposes. The Devine formula (1974) was originally created to calculate drug dosing for patients — not as a fitness target. The Hamwi formula is used in clinical nutrition to determine caloric requirements. Robinson and Miller updated these models in 1983 using different population datasets.
Each formula was derived from height-based linear regressions of population samples, which is why they produce slightly different results. None of them account for muscle mass, frame size, or ethnicity — a heavily muscled athlete and a sedentary person of the same height would get the same "ideal weight" from every formula.
Think of these values as a range rather than a fixed target. If all four formulas and the BMI range overlap on a similar number, that convergence is meaningful. Where they diverge, your frame size, fitness goals, and personal health context matter more than any single formula's output.

Exemplo Resolvido
Ideal weight estimates for a 5'10" (178 cm) male
Entradas:
- Sex: Male
- Height: 178 cm (5 ft 10 in)
Passo a Passo:
- Devine formula (1974): 50 + 2.3 × (inches over 5 ft) = 50 + 2.3 × 10 = 73.0 kg
- Miller formula (1983): 56.2 + 1.41 × (inches over 5 ft) = 56.2 + 14.1 = 70.3 kg
- Robinson formula (1983): 52 + 1.9 × (inches over 5 ft) = 52 + 19 = 71.0 kg
- Hamwi formula (1964): 48.0 + 2.7 × (inches over 5 ft) = 48 + 27 = 75.0 kg
- WHO BMI-based range (18.5–24.9): 58.7 kg – 79.1 kg
Dicas
- No single formula is 'correct' — we show all four plus the BMI range so you can see the consensus.
