Estimates only - not medical advice.
There is no single ideal weight for a given height. The calculator shows the healthy BMI range (18.5 to 24.9) alongside three classic clinical formulas: Devine, Hamwi and Robinson. Each was developed in a different decade for a different purpose. Together they bracket a reasonable range. None of them knows your muscle mass, bone density or health history.

None of them is definitively correct. The BMI-derived range is the broadest; the clinical formulas (Devine, Hamwi, Robinson) tend to produce narrower numbers. Use the spread as a starting reference, not a finish line.
The Devine formula (1974) was originally derived for drug dosing calculations. Hamwi (1964) was developed for estimating caloric needs. Robinson (1983) updated Devine using a different sample. Each produces a slightly different number because each was built for a slightly different purpose.
No. These formulas use height only and ignore muscle mass entirely. A highly trained athlete may sit well above the calculated range while being in excellent health. If body composition is a concern, a body-fat estimate is more informative.
No - an estimate.
