Reference-Weight Formula Calculator result
The four labeled formulas use their published sex-specific 5-foot base weights and per-inch additions. They are historical dosing/reference equations, not healthy-weight targets, and are not applied below 5 feet. Body composition, disability, age, ethnicity, and individual health goals are not captured.

How this tool works
For each inch above 5 feet, Robinson adds 1.9 kg (male) or 1.7 kg (female) to 52/49 kg; Miller adds 1.41/1.36 kg to 56.2/53.1 kg; Devine adds 2.3 kg to 50/45.5 kg; and Hamwi adds 2.7/2.2 kg to 48/45.5 kg. The tool does not extrapolate below 5 feet.
Limits to know
The four formulas are historical height-and-sex references originally used in clinical or dosing contexts. They are not applied below 5 feet and do not account for body composition, disability, ethnicity, age, pregnancy, or personal health goals; they are not clinical targets.
