Compare classic ideal-weight formulas and translate results into realistic target ranges.
Overview
Ideal weight formulas were created for quick clinical reference and medication planning, not as strict definitions of health.
Use ideal weight outputs as a directional range alongside BMI, body-fat percentage, and performance outcomes.
Steps
Most formulas use separate constants for men and women.
Provide height in inches or centimeters.
Compare Devine, Robinson, and Miller estimates.
Review each formula output.
Treat values as a band, not a fixed target.
Check body fat, waist, and performance markers.
Math
Devine (men): 50 + 2.3 x (inches over 60); Devine (women): 45.5 + 2.3 x (inches over 60)
Ideal-weight equations estimate body weight from height above 5 feet using a fixed incremental factor per inch.
Worked cases
IBW = 50 + 2.3(70 - 60) = 50 + 23 = 73 kg
Estimated ideal weight: 73 kg
IBW = 45.5 + 2.3(64 - 60) = 54.7 kg
Estimated ideal weight: 54.7 kg
Devine ~70.5 kg, Robinson ~72.6 kg, Miller ~71.5 kg
Use roughly 71 to 73 kg as formula-based zone
