Ideal Weight Calculator
Calculate your ideal body weight based on height and gender.
How Ideal Weight is Calculated
Uses the Devine formula (1974): Men = 50 + 2.3 kg per inch over 5 feet. Women = 45.5 + 2.3 kg per inch over 5 feet. This provides a baseline; individual ideal weight depends on body composition.
FAQ
What is ideal body weight?
A weight range associated with lowest health risks for your height and frame, typically corresponding to BMI 20-25.
Is the Devine formula accurate?
It provides a reasonable estimate but does not account for muscle mass or body composition.
Should athletes use this?
Athletes often exceed ideal weight ranges due to muscle mass. FFMI is more appropriate.
What other formulas exist?
Robinson (1983), Miller (1983), and Hamwi (1964) are alternatives with slightly different results.
