Ideal Weight Is a Range, Not a Single Digit

Ideal weight calculators use height, sex, and sometimes frame size to estimate a 'target' weight. They were often designed for clinical or insurance contexts — not aesthetics or athletic performance.
Different formulas (Robinson, Devine, Hamwi) can disagree by several kilograms for the same person. That alone tells you these are guides, not destiny.
Your best weight usually aligns with stable energy, good blood markers, strength you are proud of, and a lifestyle you can maintain.
Use ideal weight calculators as one data point alongside body composition, waist-to-height ratio, and how you perform in daily life.
If recovering from disordered eating, skip weight targets entirely until you work with a healthcare provider.
