What Is Ideal Weight Calculator?
The Ideal Weight Calculator puts four published reference formulas side by side for your height and sex: Devine, Robinson and Hamworth, plus Miller as soon as you supply an age. Every figure is given in kilograms and pounds, with the average of the three height-only formulas presented as the headline number. Laying them out together makes plain that these formulas do not agree with one another.
Who Uses the Ideal Weight Calculator?
People who want a neutral reference point for their weight, students comparing the classic formulas, and writers checking how the older published tables differ use it. Clinicians often point clients at these numbers precisely to show how wide the spread between them is.
How to Use the Ideal Weight Calculator
- Choose Centimetres (cm) or Inches (in) with the height units buttons, select Male or Female, and enter your Height.
- Add your Age in years if you want the Miller formula included, since it is the only one of the four that uses age at all.
- Press the compare button to see every result in kg and lb alongside the average, with your height restated in feet and inches.
Why Choose Our Ideal Weight Calculator?
- Four named formulas compared in a single table, so you can see exactly where Devine, Robinson, Hamworth and Miller disagree for your height
- Entering an age unlocks Miller, and the note beneath the table explains why that result is held outside the average
- Reports in kilograms and pounds side by side, removing the need to convert between the two systems by hand
- Carries an explicit medical disclaimer that these are population averages ignoring muscle mass and body composition, not a prescription or a target
