What is Ideal Body Weight?
There is no single universally agreed-upon ideal body weight — different medical formulas give different answers based on height, gender, and body frame size. Our calculator shows you results from four widely-used clinical formulas so you can see the range of healthy weights for your height.
The Four Ideal Weight Formulas
- Devine Formula (1974): The oldest, originally developed for drug dosage calculations. Still widely used in clinical practice.
- Robinson Formula (1983): A refinement of Devine, considered slightly more accurate.
- Miller Formula (1983): Tends to produce lower weight estimates, especially for taller individuals.
- Hamwi Formula (1964): Allows for frame size adjustments — add 10% for large frames, subtract 10% for small frames.
📌 The Healthiest Metric: Body Composition
Ideal weight charts are a general guide. What matters most is your body composition — the balance of muscle to fat. A fit 80kg athlete may be far healthier than a sedentary 65kg person. Use this alongside our BMI and Body Fat calculators for a complete picture.
Frequently Asked Questions
While the Devine (1974) formula is widely used in medical settings, no single formula is perfect. Our calculator uses a blend of established biometric formulas to provide a realistic target range.
No. Standard ideal weight equations rely solely on height and sex. A bodybuilder may weigh well above their 'ideal weight' purely due to heavy muscle tissue, yet remain immaculately healthy.
Not implicitly. The range is a statistical average for longevity. Having a heavier skeletal structure or high athletic mass naturally shifts your healthy zone outside of generalized mathematical formulas.
