Ideal weight formulas give a rough healthy range for your height. They ignore muscle, so if you lift, aim for a body fat target rather than a single number on the scale.
How this ideal weight calculator works
Four classic formulas (Devine, Robinson, Miller, Hamwi) start from a base weight at 5 feet and add a set amount per inch. The Asian healthy BMI range (18.5 to 22.9) is shown alongside them.
Frequently asked questions
Which formula is most accurate?
None is accurate for an individual. They agree within a few kg; use the overlap as a rough guide.
