Body Health CalculatorIdeal Weight Chart by Height (Devine, Robinson, Miller, Hamwi)
Averaging the Devine, Robinson, Miller, and Hamwi formulas, ideal body weight runs from about 114 lb (male) / 106 lb (female) at 5'0" to about 178 lb (male) / 165 lb (female) at 6'2". These formulas were built for medication dosing, not personal weight goals.

Four formulas, one reference chart
Ideal body weight (IBW) formulas were built for clinical dosing and nutrition estimates, not as a personal weight goal. The most common four are Devine, Robinson, Miller, and Hamwi, each a linear formula off a 5-foot baseline. They roughly agree at typical adult heights and diverge more at height extremes.
The table below averages all four formulas by height and sex. Individual calculators may show any one formula on its own; this page is a quick-reference chart, not a substitute for the full calculator.
Average ideal body weight by height
Values are the average of Devine, Robinson, Miller, and Hamwi formulas, rounded to the nearest tenth of a pound.
Average IBW by height and sex
| Height | Male (avg. IBW) | Female (avg. IBW) |
|---|---|---|
| 5'0" (60 in) | 113.7 lb | 106.4 lb |
| 5'2" (62 in) | 122.8 lb | 114.8 lb |
| 5'4" (64 in) | 132.0 lb | 123.1 lb |
| 5'6" (66 in) | 141.1 lb | 131.4 lb |
| 5'8" (68 in) | 150.3 lb | 139.8 lb |
| 5'10" (70 in) | 159.5 lb | 148.1 lb |
| 6'0" (72 in) | 168.6 lb | 156.4 lb |
| 6'2" (74 in) | 177.8 lb | 164.8 lb |
Why the four formulas do not match exactly
Devine (1974) was designed for drug dosing, especially aminoglycoside antibiotics, and is the version most clinical software defaults to. Robinson (1983) and Miller (1983) refined it against different reference populations. Hamwi (1964) predates the others and was built as a quick bedside estimate for nutrition planning.
None of the four account for frame size, muscle mass, or body composition. A muscular person and a person with higher body fat at the identical height get the same IBW number, which is why these formulas are used for dosing reference more than personal weight targets.
How to use this chart
Clinicians most often use IBW to size medication doses, not to set weight-loss goals. If you are targeting a personal weight, body fat percentage, waist-to-height ratio, or how your clothes fit are generally more useful than IBW alone.
If a calculator or care team member asks specifically for "Devine IBW" for a dosing calculation, use the single-formula calculator rather than the averaged chart on this page.
FAQs
Which ideal body weight formula is most accurate?
None is "most accurate" for general health; they were built for different purposes, mainly medication dosing. Devine is the most widely used default in clinical software. This chart averages all four for a general reference point.
Should I try to weigh exactly my ideal body weight?
Not necessarily. IBW formulas ignore muscle mass, frame size, and body composition. A muscular person may weigh well above their IBW with a healthy body fat percentage. Use IBW as one reference point, not a strict target.
Why does my ideal weight change between calculators?
Different tools default to different formulas (Devine, Robinson, Miller, Hamwi) or report a single formula instead of an average. Check which formula a tool uses before comparing numbers across sites.
