How This Calculator Works

Unlike simple BMI calculators, this tool combines four distinct medical formulas to provide a precise range. It also adjusts for your body frame size, recognizing that bone structure affects healthy weight.

  • Devine Formula (1974): The most widely used standard for medical dosages.
  • Robinson Formula (1983): An improvement on Devine, often used for men.
  • Miller Formula (1983): Typically results in a lower ideal weight estimate.
  • Hamwi Formula (1964): A classic "Rule of Thumb" used in clinical settings.

The "Healthy BMI Range" is based on the World Health Organization standard of 18.5 - 24.9 kg/m².
