⚖️ Ideal Weight Calculator
What is the Ideal Weight Calculator?
The Ideal Weight Calculator estimates a healthy target weight range from your height and sex using four established clinical formulas: Devine, Robinson, Miller, and Hamwi. Enter your height, sex, and current weight, and it returns each formula's estimate along with an average, so you can compare your current weight to a research-based range instead of a single number.
How to Use It
Enter your height in centimeters, select male or female, and enter your current weight in kilograms, then press Calculate. The results show the ideal weight predicted by each of the four formulas plus the average of all four, alongside your current weight in both kilograms and pounds for easy comparison.
When to Use It
Use it when setting a realistic weight goal, checking how your current weight compares to commonly used clinical reference ranges, or discussing medication dosing benchmarks (several of these formulas were originally developed for that purpose) with a healthcare provider. It's a starting point for conversation, not a diagnosis.
Who Benefits
Anyone starting a weight management plan, athletes and trainers setting benchmarks, and patients preparing questions for a doctor's visit can use it to see a range rather than fixating on one target. Because the four formulas differ, especially for taller or shorter people, use the spread between them as a sanity check.
