What is a ideal weight?

Ideal-weight formulas provide historical reference estimates based on height and sex. They do not account for body composition, age, ethnicity, health conditions or individual goals. Treat this number as one rough reference rather than a target or medical recommendation.

Formula and calculation method

Devine reference: men = 50 kg + 2.3 kg per inch over 5 ft; women = 45.5 kg + 2.3 kg per inch over 5 ft.

The result is only as reliable as the inputs and assumptions. This tool is educational and does not replace professional financial, medical, legal or academic advice.
