Healthy weight range using BMI, Hamwi, Devine and Miller formulas with BMI zone chart
This calculator identifies a healthy weight range for your height using multiple methods — the WHO BMI range (18.5–24.9), and three clinical ideal weight formulas (Hamwi, Devine, and Miller). Showing all methods together helps you understand where there is consensus and where you might set a realistic weight target.
Frequently Asked Questions
Sobre Esta Calculadora
A "healthy weight" is a range, not a single number. The WHO BMI-based range (18.5–24.9) gives a broad window based on population-level cardiovascular risk data. The clinical formulas (Hamwi, Devine, Miller) were developed for specific medical purposes like drug dosing and nutritional planning, and they converge on a narrower midpoint within the BMI range.
None of these approaches are perfect. They don't account for muscle mass distribution, age-related changes in body composition, or ethnicity-based differences in risk thresholds. Some research suggests Asian populations have elevated metabolic risk at BMI values as low as 23, while musculoskeletal athletes may be healthiest at BMI values above 25.
The most practically useful application of this calculator is to establish a target weight range for gradual, sustainable progress. A 1–2 kg monthly change is generally achievable and clinically safe. Dramatic, rapid weight changes — in either direction — carry health risks independent of the goal.

Exemplo Resolvido
Healthy weight range for a 5'6" (168 cm) woman
Entradas:
- Sex: Female
- Height: 168 cm (5 ft 6 in)
Passo a Passo:
- WHO BMI range (18.5–24.9): min = 18.5×(1.68)² = 52.2 kg | max = 24.9×(1.68)² = 70.3 kg
- Hamwi formula (female): 45.4 + 2.27 × (inches over 5 ft) = 45.4 + 2.27 × 6 = 59.0 kg
- Devine formula (female): 45.5 + 2.3 × (inches over 5 ft) = 45.5 + 13.8 = 59.3 kg
- Miller formula (female): 53.1 + 1.36 × (inches over 5 ft) = 53.1 + 8.16 = 61.3 kg
