Ideal Weight Calculator
Calculate your ideal weight range using multiple scientific formulas and body frame size
About this calculator
The Ideal Weight Calculator determines your optimal weight range using scientifically-backed formulas including BMI, Robinson, Miller, Devine, and Hamwi methods. By considering your height, age, gender, and body frame size, it provides a comprehensive assessment rather than a single number. This multi-formula approach gives you a more accurate and personalized target range, helping you set realistic health and fitness goals based on your unique body composition and structure.
How to use
Enter your height, weight, age, and select your gender in the calculator fields. Choose your body frame size (small, medium, or large) based on wrist circumference or elbow breadth measurements. Click calculate to see your ideal weight range across multiple formulas and determine which target range best suits your body type.
Frequently asked questions
Which formula is most accurate for ideal weight?
No single formula is perfect. Our calculator uses multiple methods to provide a comprehensive range, as individual body composition varies significantly between people.
How do I determine my body frame size?
Measure your wrist circumference or elbow breadth. Small frames have smaller measurements, while large frames have bigger bone structures and joint widths.
Why do the different formulas show different results?
Each formula was developed for different populations and purposes. The variation shows why using multiple methods provides a more realistic weight range.
