Calculate your ideal body weight using the Miller formula (1983). Gives the highest IBW estimates among the four major formulas — a more generous reference weight for your height.
The Miller formula is a historical ideal body weight equation that is still reproduced in clinical references. It uses a higher base weight and a relatively small per-inch increase, which can make it a useful upper comparison point among common IBW formulas.
Because it was developed empirically, it should be treated as a reference equation rather than a precise or universal standard.
Miller is one of several historical IBW equations. It can be useful when you want to compare a higher-end IBW estimate against other formulas, but it should not be treated as inherently more accurate.
Men: IBW = 56.2 + 1.41 × (height in inches − 60) Women: IBW = 53.1 + 1.36 × (height in inches − 60) Result in kg. Healthy range: IBW ± 10%
Result: IBW: 70.3 kg (155 lbs) | Range: 63.3–77.3 kg
Male at 5'10" (70 inches): IBW = 56.2 + 1.41 × (70 − 60) = 56.2 + 14.1 = 70.3 kg (155 lbs). Miller gives a lower IBW than Devine (73.0 kg) at this height because the per-inch increment is only 1.41 kg vs. Devine's 2.3 kg.
Miller is one of several historical ideal-body-weight equations. Its smaller per-inch increment means it can sit at the higher end of the comparison range at shorter heights and shift lower relative to some other formulas at taller heights.
For practical use, the value of Miller is in comparison. Looking at Miller alongside Devine, Robinson, and Hamwi shows the spread between reference equations and makes it easier to avoid treating any one formula as exact.

This calculator applies the Miller ideal-body-weight equation and shows it as a historical reference estimate. The comparison range is intentionally descriptive: different equations were built from different assumptions, so disagreement between formulas is expected.
The page does not claim that Miller is more accurate than the others. It simply exposes the equation, shows the result, and lets the user compare it with neighboring reference formulas.
Miller is commonly reproduced as a historical ideal-body-weight equation with a higher base and smaller height increment than some older formulas. That makes it useful for comparison, but not for identifying one correct weight.
Miller and Robinson often produce higher values than Devine at shorter heights. Which one is most useful depends on the purpose, but none should be treated as a universal standard.
The formulas can differ by several kilograms at the same height because they were derived from different historical assumptions and datasets. That spread is normal and is why they are best read as a range, not a verdict.
Neither. Miller is best understood as one historical estimate among several.
No single formula is correct for all people. Comparing several formulas can help show the range of historical estimates for the same height.
No. Like all four major IBW formulas, Miller assumes a medium body frame.
