Body weight formulas

Ideal Weight Calculator

Compare Devine and Robinson ideal-weight estimates from height. These formulas are reference points, not personal targets.

How to read the estimate

Ideal-weight formulas were developed for broad clinical estimates. They do not account for frame size, ethnicity, muscle mass, health status or personal goals, so compare the result with other health context rather than treating it as a required weight.

Example

For a 175 cm adult, the calculator converts height to the units used by the formulas and compares the Devine and Robinson estimates. The result is a formula-based reference range, not a diagnosis.

Common mistakes

Do not use ideal-weight formulas to judge athletic bodies, pregnancy, children, older adults or people with unusual body composition. Height-only formulas miss important context.

Limitations

This page is informational and not medical advice. Discuss weight goals with a qualified health professional if the result affects treatment, nutrition planning or body image concerns.
