Ideal weight formulas

Several formulas — Devine, Robinson, Miller and Hamwi — have been used since the mid-20th century to estimate a "reference" body weight from height alone, originally for medical dosage calculations. They're rough guides rather than personalized targets; body composition, frame size and muscle mass all matter more than any single number on a scale.
