Ideal Weight Calculator
Compare the Devine, Robinson and Miller formulas side by side, plus the healthy BMI weight range for your height.
| Devine (1974) | 70.6 kg |
|---|---|
| Robinson (1983) | 73.4 kg |
| Miller (1983) | 72 kg |
| Healthy BMI range | 56.7 – 76.3 kg |
These are reference values from old dosing formulas, not beauty standards.
What is it
“Ideal weight” is not one number — it is what three classic doctor formulas guess from your height alone. Devine, Robinson and Miller were built to dose medicines in the 1970-80s, and they still disagree slightly. Alongside them, the healthy BMI window shows the weight that doctors today consider reasonable for your height.
Notes & fun facts
The funny secret of these formulas: none of them was ever designed to tell you whether you look good. Devine was built to dose antibiotics by body weight, and his “ideal” values were really “useful dosing weights”. Generations of patients have been weighed against a number invented for pharmacy tables.
Origin & history
The Devine formula appeared in 1974, in a drug-dosing paper by B. J. Devine. In 1983, Robinson proposed a refined version, while Miller published another linear estimate the same year. All three assumed “ideal = height minus fixed offset”, and none has been retired — because nothing practical replaced them.
