Note: These formulas were developed for clinical dosing purposes, not aesthetic goals. They do not account for muscle mass, build, or ethnicity. The healthy BMI weight range is a broader and more accepted standard.
See your ideal body weight estimated by four clinically-used formulas — Robinson, Miller, Hamwi, and Devine — plus the healthy BMI weight range for your height. Supports metric and imperial, and shows results for both men and women.
Key Features
Four formula comparison
Robinson (1983), Miller (1983), Hamwi (1964), and Devine (1974) ideal weight formulas are all calculated and shown side by side.
Formula average
A single averaged value across all four formulas gives a balanced ideal weight estimate at a glance.
Healthy BMI range
The WHO healthy BMI range (18.5–24.9) is converted to a weight range for your specific height, providing a broader and more accepted reference.
Metric and imperial
Results appear in both kg and lb when using imperial, no manual conversion needed.
