Understanding Ideal Weight
Ideal weight is a recommended weight range based on your height and gender. There is no single "perfect" number - every height has a healthy weight range, typically based on a BMI between 18.5 and 24.9.
Common Formulas
- Robinson (1983) - Modern, widely used
- Miller (1983) - Modern alternative
- Devine (1974) - Standard in medical settings
- Hamwi (1964) - Oldest of the four
Each formula gives slightly different results. The average is a reasonable target.
