An Ideal Body Weight (IBW) Calculator provides healthy target weight ranges using recognized clinical formulas originally developed for medical dosing and nutritional planning.
Formulas Overview: Devine Formula (Men: 50 kg + 2.3 kg per inch over 5ft; Women: 45.5 kg + 2.3 kg per inch over 5ft); Robinson Formula (Men: 52 kg + 1.9 kg/inch; Women: 49 kg + 1.7 kg/inch); Hamwi Formula (Men: 48 kg + 2.7 kg/inch; Women: 45.5 kg + 2.2 kg/inch).
Range Interpretation: Because body frame size, bone density, and muscle mass vary, ideal weight is best viewed as a 10%–15% healthy range rather than a single rigid number.
Goal Setting: Use IBW alongside body fat measurements to establish realistic, sustainable fitness and weight management goals.
What is the Devine formula for Ideal Body Weight?
The Devine formula sets a baseline at 5 feet tall (50 kg for men, 45.5 kg for women) and adds 2.3 kg for each additional inch of height.
