Show reference weight ranges for a height
The featured result is the kilogram interval that matches BMI 18.5 to 24.9 for your height. Devine, Robinson, and Miller are historical conventions, not a weight “to aim at.”
Calculate
How the calculator works
Height alone sets the WHO interval: low = 18.5 × m², high = 24.9 × m². That is transparent: the same bounds as the BMI calculator, inverted. Then three Anglo-American “ideal body weight” formulas display for memory. Devine (1974) was proposed in a gentamicin dosing article, not as a public-health goal. Robinson and Miller are other conventions in the same family (base weight + a term per inch above 5 feet). We cite Devine and WHO; we do not invent papers for Robinson and Miller, while documenting the coefficients the engine actually uses.
Formula and method
Intervalle = [18,5 × taille(m)² ; 24,9 × taille(m)²]
Adult WHO BMI bounds, converted to kg. Featured.
Devine homme : 50 + 2,3 × (pouces − 60) | femme : 45,5 + 2,3 × (pouces − 60)
Inches = height(cm)/2.54. Origin: dosing, Devine 1974.
Robinson homme : 52 + 1,9 × (pouces − 60) | femme : 49 + 1,7 × (pouces − 60)
Historical convention in the same family, without an invented source here.
Miller homme : 56,2 + 1,41 × (pouces − 60) | femme : 53,1 + 1,36 × (pouces − 60)
Same: comparison display, not a target.
A single “ideal weight” is a marketing idea more than a physiologic quantity. The 18.5–24.9 interval inherits adult BMI classes; it remains silent on muscle and health. Devine still appears in some dosing (ideal vs actual vs adjusted weight), which explains its survival: that is not proof you should weigh that number. Showing Robinson and Miller shows that even stature conventions disagree. None is reviewed by a physician on this site.
Worked example
Woman, 170 cm (about 5 ft 7 in)
170 cm, female.
- height² = 1.70² = 2.89.
- BMI 18.5 → 53.5 kg; BMI 24.9 → 72.0 kg.
- Inches above 5 feet: 170/2.54 − 60 ≈ 6.93.
- Devine = 45.5 + 2.3 × 6.93 ≈ 61.4 kg; Robinson ≈ 60.8 kg; Miller ≈ 62.5 kg.
Featured interval: about 53.5 to 72.0 kg (about 118 to 159 lb). Devine ≈ 61.4 kg is not “the” weight to hit.
Input notes
- Height
- Only anthropometry for the BMI interval. Below 140 cm or above 220 cm, the inches-above-5-feet formulas get acrobatic: the tool bounds input.
- Sex
- Unused for 18.5–24.9. Used only for Devine / Robinson / Miller.
Assumptions and limits
Assumptions
- Adult, height in 140–220 cm.
- Bounds 18.5 and 24.9 are those already used for adult BMI on this site.
- 5 feet = 60 inches as the origin of the Anglo-American formulas.
Limits
- Not a personal target, not a sport “fight weight.”
- Useless in pregnancy, in children, in large muscle mass, in edema.
- Devine is not a slimming goal; it is a convention born of dosing.
- Robinson and Miller have no invented scientific leaflet here.
How to read the result
If Devine falls in the 18.5–24.9 interval, that is almost tautological for many average heights — it does not validate Devine. If you are outside the BMI interval, the page does not tell you to “join Devine.” It mostly shows that a single magic kilogram does not exist. For current weight/height, BMI; for a fat estimate, Navy.
Common mistakes
Taking Devine as a health weight to reach.
Devine comes from a 1974 gentamicin paper. It is not a weight-loss program.
Believing 18.5–24.9 is a mandatory corridor for every adult.
It is the adult WHO “normal weight” band, with all of BMI’s limits.
Averaging Devine, Robinson, and Miller for “more precision.”
The mean of three conventions is not metrology. The BMI interval is already more readable.

Related calculations
- BMI calculatorBody mass index is weight in kg divided by height in meters squared. Labels use adult WHO cut-offs. That is not an obesity diagnosis by itself, and it is not a child BMI.
- Body fat (Navy method)The percent comes from Hodgdon and Beckett (1984) circumference equations for the US Navy: logarithms and measurements converted to inches. It is a field estimate, not absorptiometry.
Frequently asked questions
Why say “ideal” if it is not one?
Because people still search that phrase. The content refuses to make it a personal target.
The slug and everyday name stay recognizable. The H1 and the main result speak of reference and an interval. Devine is explained as historical.
Is Devine still used in medicine?
Some dosing calculations still use it. That is not a reason to make it an aesthetic goal.
The 1974 article concerns gentamicin. Modern pharmacokinetics has other tools. We give no drug advice.
Does the BMI interval depend on sex?
Not in this tool: 18.5 and 24.9 apply to the same kg/m² for both formula sexes.
The adult WHO classes used here are not sex-specific. Devine & co. formulas are.
I lift. Which number should I follow?
None of these historical kg figures. BMI and Devine ignore muscle.
A weight “in the interval” can coexist with very low or very high adiposity. The Navy method estimates something else, with other flaws. Athletic follow-up sits outside these 1974 conventions.
