What is the Hamwi Method?

Hamwi Method is an IBW formula that is used extensively to determine a healthy range of weight in adults. It takes into account height and gender and generates a weight that is then used as a foundation for medical, nutritional, and fitness applications.(see more)

  • Primary aim: To determine the optimal body weight of adults.
  • Invented by: Dr. Hamwi, who is a doctor specializing in the evaluation of health by weight.

Applications: Clinical medicine, diet planning, and fitness goal setting.

  • 106 lbs first 5 feet + 6 lbs each inch above 5 feet: men.
  • Women: 100lbs between the first 5 feet together with 5 lbs every inch after the first 5 feet.

Example:

  • A man who is 6 feet tall (72 inches):
    106 + (6 × 12) = 106 + 72 = 178 lbs
  • A woman who is 5 feet 6 inches tall (66 inches):
    100 + (5 × 6) = 100 + 30 = 130 lbs

This calculation can also be done using a Hamwi calculator, which automates the process for convenience.
