Ideal Weight Calculator
Determine your ideal weight using four medical formulas and healthy BMI ranges based on your frame size.
Find your target weight range:
Step 1: Select your gender and enter your height in centimeters.
Step 2: Select your body frame size (Small, Medium, or Large).
Step 3: Calculate to see a detailed comparison of the Devine, Robinson, Miller, and Hamwi formulas.
Step 4: Review the World Health Organization (WHO) healthy BMI weight range (18.5 - 25) for your height.
We use the four most respected medical formulas:
1. Devine (1974): The medical standard for drug dosing. 2. Robinson (1983): Modified Devine for better accuracy in men. 3. Miller (1983): Modified Devine for better accuracy in women. 4. Hamwi (1964): The original clinical standard.
Adjustments: We adjust results by ±10% for Small and Large frame sizes to account for bone density and muscle potential.
