Ideal Weight Calculator
Calculate ideal body weight using Devine, Robinson, Miller, and Hamwi formulas.
What Is the Ideal Weight Calculator?
Ideal body weight (IBW) formulas provide guidelines for healthy weight ranges based on height and gender. Different formulas (Devine, Robinson, Miller, Hamwi) were developed for different medical contexts.
Formula
How to Use
Enter your height and gender. The calculator shows ideal weight ranges from four commonly used medical formulas and compares with your current weight if entered.
Example Calculation
Male, 5ft 10in (178cm): Devine IBW = 72.5 kg, Robinson = 74.4 kg, Miller = 72.0 kg, Hamwi = 77.1 kg. Average ideal weight is approximately 74 kg.

Frequently Asked Questions
Which formula is most accurate?
No single formula is universally best. The Devine formula was developed for drug dosing; all are approximations. Body composition (muscle vs fat) matters more.
Is BMI better than IBW?
BMI accounts for weight relative to height but ignores body composition. IBW is better for medication dosing. Neither replaces professional medical assessment.
Does ethnicity affect ideal weight?
Asian populations may have different optimal BMI ranges. Some formulas have been adapted for specific populations.
