What this calculator does
An ideal weight calculator estimates optimal body weight based on height using established formulas like Devine, Robinson, or Hamwi. These formulas provide reference ranges, not absolute targets, since body composition and frame size affect individual ideals.
How it works
Enter height and sex. The calculator applies formulas (Devine: base weight + adjustment per inch) to estimate ideal weight.
Formula
Devine (men): 50 kg + 2.3 kg per inch over 5 ft. Devine (women): 45.5 kg + 2.3 kg per inch over 5 ft. Adjust ±10% for frame size.
Tips for using this calculator
- Ideal weight is a range, not single number
- Frame size affects appropriate weight (±10%)
- Muscle mass isn't captured in formulas
- Focus on body composition over scale weight
- Consult healthcare provider for personalized goals
Frequently asked questions
Why do formulas give different results?
Different populations and methods produced different formulas. Use as reference ranges, not absolutes.
Should I aim for the exact number?
