About this calculator

Ideal body weight (IBW) formulas estimate a reference weight from height and sex. They differ slightly because each was fitted to different clinical data. All start from a base weight at 5 feet and add per-inch increments.

Formula

Devine: men 50 + 2.3×(in−60) kg · women 45.5 + 2.3×(in−60) kg (Robinson, Miller, and Hamwi use the same structure with different constants)
