These formulas were built for adults, originally to dose medicines. They ignore muscle and frame size, so treat them as a range, not a target.

How it was calculated

  1. Robinson (1983): 52 kg + 1.9 kg × 10 in over 5 ft = 71 kg
  2. Miller (1983): 56.2 kg + 1.41 kg × 10 in over 5 ft = 70.3 kg
  3. Devine (1974): 50 kg + 2.3 kg × 10 in over 5 ft = 73 kg
  4. Hamwi (1964): 48 kg + 2.7 kg × 10 in over 5 ft = 75 kg

How the ideal weight calculator works

Each formula starts from a base weight at 5 feet and adds a fixed amount for every inch above it. Devine (1974): men 50 kg + 2.3 kg per inch, women 45.5 kg + 2.3 kg. Robinson (1983): men 52 + 1.9, women 49 + 1.7. Miller (1983): men 56.2 + 1.41, women 53.1 + 1.36. Hamwi (1964): men 48 + 2.7, women 45.5 + 2.2.

The healthy BMI range (18.5 to 25) gives a wider band that many doctors use today. None of these account for muscle, age or frame, so a fit, muscular person can be healthy above them.
