Understanding Ideal Body Weight
Ideal body weight (IBW) is an estimated healthy weight for a person based on their height and sex. While originally developed for medication dosing in medical settings, IBW formulas provide a general guideline for healthy weight ranges. However, they don't account for individual factors like muscle mass, bone density, or body composition.
The Four Main Formulas
Devine Formula (1974): Most widely used in medical practice. Men: 50kg + 2.3kg per inch over 5ft. Women: 45.5kg + 2.3kg per inch over 5ft.
Robinson Formula (1983): A refinement of Devine. Men: 52kg + 1.9kg per inch over 5ft. Women: 49kg + 1.7kg per inch over 5ft.
Miller Formula (1983): Similar to Robinson with slight variations. Men: 56.2kg + 1.41kg per inch over 5ft. Women: 53.1kg + 1.36kg per inch over 5ft.
Hamwi Formula (1964): Simple quick calculation. Men: 48kg + 2.7kg per inch over 5ft. Women: 45.5kg + 2.2kg per inch over 5ft.
Limitations of Ideal Weight Formulas
These formulas were developed for average population groups and have significant limitations. They don't account for athletes with high muscle mass, individuals with different bone densities, or variations in body composition. A bodybuilder and a sedentary person of the same height and sex would have very different healthy weights.
Using IBW as a Guideline
Use ideal weight as one of several health indicators, not an absolute target. Focus on body composition, fitness level, and health markers like blood pressure, cholesterol, and blood sugar. Consult with healthcare professionals for personalized weight recommendations based on your individual circumstances.
Important Note
Ideal weight calculators provide general estimates only. Your healthy weight depends on many individual factors. Always consult with a healthcare provider for personalized health advice.
Frequently Asked Questions
What is ideal body weight?
Ideal body weight (IBW) is an estimated healthy weight range based on height and sex. It's calculated using medical formulas developed for health assessment.
Which ideal weight formula is most accurate?
No single formula is perfect. The Devine formula is widely used medically. The Robinson and Miller formulas are also reliable. We show multiple formulas for comparison.
Does ideal weight account for muscle mass?
No, ideal weight formulas are based on population averages and don't account for individual muscle mass, bone density, or body composition.
Is ideal weight the same as BMI?
No, BMI is a ratio of weight to height. Ideal weight formulas estimate a specific healthy weight range based on your height.
Should I weigh my ideal body weight?
