Understanding Your Ideal Weight: Formulas and Reference Data
Determining an ideal weight is not an exact science, as it depends on various factors including body composition, muscle mass, bone density, and overall health. This calculator computes both the Hamwi formula and the Devine formula from your height and gender and shows the range between them — it does not use your current weight, since neither formula takes weight as an input.
The Hamwi formula, developed by Dr. George Hamwi in 1964, is a simple and widely used method. For men, it's 106 pounds for the first 5 feet of height, plus 6 pounds for each additional inch. For women, it's 100 pounds for the first 5 feet, plus 5 pounds for each additional inch.
The Devine formula, created by Dr. Willard Devine in 1974, is another popular choice. For men, it's 50 kg for the first 5 feet of height, plus 2.3 kg for each additional inch. For women, it's 45.5 kg for the first 5 feet, plus 2.3 kg for each additional inch.
While these formulas provide a baseline, it's important to remember that they are estimations. A healthy weight is best determined in consultation with a healthcare professional who can consider your individual circumstances.
