How Our Advanced Ideal Weight Calculator Works
Our 2026 ideal weight calculator uses multiple clinically validated formulas to provide the most accurate healthy weight range for your specific body metrics. Unlike basic tools, we adjust for age, gender, height, and crucially, body frame size—a factor often overlooked but essential for accuracy.
Key Formulas Applied
- Devine Formula (1974): Widely used in medical dosing calculations
- Robinson Formula (1983): Developed from actuarial statistics
- Miller Formula (1983): Revision of Devine formula
- Hamwi Formula (1964): Common in clinical settings
Our algorithm calculates all four formulas, then applies frame-size adjustments (±10% for small/large frames) to generate your personalized range.
BMI Integration
We integrate Body Mass Index (BMI) calculations to categorize your result according to World Health Organization standards:
| BMI Range | Category |
|---|---|
| < 18.5 | Underweight |
| 18.5–24.9 | Normal weight |
| 25.0–29.9 | Overweight |
| ≥ 30.0 | Obesity |
