Example 1: Devine male
Input
- Height: 5 ft 10 in (70 in)
Calculation
IBW = 50 + 2.3(70 - 60) = 50 + 23 = 73 kg
Result
Estimated ideal weight: 73 kg
Compare classic ideal-weight formulas and translate results into realistic target ranges.
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.
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.
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.
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
