The average of all four scientific formulas, adjusted for your body frame size.
BMI-based healthy weight range (BMI 18.5-24.9) for optimal health outcomes.
Individual results from Hamwi, Devine, Robinson, and Miller formulas for comparison.
If current weight is provided, shows difference from ideal weight and current BMI.
Men: 48 kg + 2.7 kg × (height in inches - 60)
Women: 45.5 kg + 2.2 kg × (height in inches - 60)
Men: 50 kg + 2.3 kg × (height in inches - 60)
Women: 45.5 kg + 2.3 kg × (height in inches - 60)
Men: 52 kg + 1.9 kg × (height in inches - 60)
Women: 49 kg + 1.7 kg × (height in inches - 60)
Men: 56.2 kg + 1.41 kg × (height in inches - 60)
Women: 53.1 kg + 1.36 kg × (height in inches - 60)
Person: Male, 175 cm (69 inches), medium frame
Hamwi: 48 + 2.7 × (69-60) = 48 + 24.3 = 72.3 kg
Devine: 50 + 2.3 × (69-60) = 50 + 20.7 = 70.7 kg
Robinson: 52 + 1.9 × (69-60) = 52 + 17.1 = 69.1 kg
Miller: 56.2 + 1.41 × (69-60) = 56.2 + 12.69 = 68.9 kg
Average: (72.3 + 70.7 + 69.1 + 68.9) ÷ 4 = 70.3 kg
Understanding your ideal weight is important for setting realistic health goals and maintaining optimal well-being:
This calculator uses multiple validated formulas to provide a comprehensive view of ideal weight ranges rather than a single number.
Medical Dosing: Healthcare providers use ideal weight formulas for medication dosing and treatment planning.
Fitness Goals: Personal trainers and individuals use these calculations to set realistic weight targets.
Insurance: Life and health insurance companies may use these formulas for risk assessment.
Sports & Athletics: Athletes use ideal weight ranges for performance optimization in weight-class sports.
No single formula is perfect for everyone. The Hamwi formula is most commonly used clinically, but averaging multiple formulas provides a more comprehensive estimate.
These formulas work best for average builds. Very muscular individuals or those with unusual body proportions may need personalized assessment from healthcare providers.
Use the wrist test: wrap your thumb and middle finger around your wrist. If they overlap easily (small), barely touch (medium), or don't touch (large frame).
Focus on the healthy weight range rather than an exact number. Health is more important than hitting a specific weight target.
Our ideal weight calculator uses four well-established formulas from medical and pharmaceutical research:
Note: These formulas provide estimates based on height and gender. Individual ideal weight may vary based on body composition, bone density, muscle mass, and overall health. Consult healthcare professionals for personalized weight management advice.
Ideal body weight (IBW) represents the weight range associated with optimal health outcomes, longevity, and reduced disease risk. Unlike arbitrary beauty standards, IBW is based on scientific research linking specific weight ranges to improved cardiovascular health, metabolic function, and overall mortality rates. Understanding your ideal weight helps guide realistic health goals and medical treatment decisions.
Ideal body weight formulas were developed through extensive population studies and clinical observations. Each formula represents decades of research correlating height, weight, and health outcomes across diverse populations, with ongoing refinements based on modern health data and demographic changes.
