Hamwi (1964): Men: 48 kg + 2.7 kg per inch over 5ft. Women: 45.5 kg + 2.2 kg per inch over 5ft. One of the most widely used in clinical settings.
Devine (1974): Men: 50 kg + 2.3 kg/inch. Women: 45.5 kg + 2.3 kg/inch over 5ft. Originally developed for medication dosing, widely adopted as a general IBW formula.
Robinson (1983): Men: 52 kg + 1.9 kg/inch. Women: 49 kg + 1.7 kg/inch over 5ft. Slight variation accounting for frame differences.
Miller (1983): Men: 56.2 kg + 1.41 kg/inch. Women: 53.1 kg + 1.36 kg/inch over 5ft. Tends to produce higher ideal weights for taller individuals.
BMI Range: The healthy BMI range (18.5–24.9) translated to weight for your height. The widest range — acknowledges that a single ideal weight is arbitrary.
Important: No single ideal weight formula is definitive. Muscle mass, bone density, age, and ethnicity all affect what "ideal" means for you. Use these as ranges, not exact targets.
⚠️ Ideal weight formulas are population-based estimates and do not account for muscle mass, body composition, or individual health status. Consult a healthcare provider for personalized weight guidance.
