Ideal Weight (Body-Weight Formulas)
Devine, Robinson, Miller, and Hamwi formula estimates of a healthy weight for your height — planning references, not military standards.
Formula
Devine men: 50 + 2.3 kg per inch over 5 ft · (women: 45.5 + 2.3) — formulas differ slightly by method.
Healthy range
Formula-dependent; always pair with WHtR or body-fat %, since weight alone cannot judge composition.
Military & first-responder angle
Historical height-weight tables operated on the same idea; 2026 replaced them with WHtR. Treat ideal-weight outputs as context, not a standard.
Calculator
Healthy weight range for a height from the BMI 18.5–24.9 band — the band most accession screens sit within.
