Frequently Asked Questions About Ideal Weight Calculator
What is ideal body weight?
Ideal body weight is an estimate of a healthy weight for your height and gender. Several formulas exist (Devine, Robinson, Miller, Hamwi), and they give slightly different numbers, so it is best to think in terms of a range.
Which ideal weight formula is best?
There is no single best one. The Devine formula is the most widely used (originally for medication dosing). This tool shows all four plus the healthy BMI range so you get a balanced picture instead of one figure.
Is ideal weight the same as healthy weight?
Not exactly. Ideal weight formulas are based only on height and gender, while a healthy weight also depends on muscle, frame size, and body composition. Use the result as a guide and pair it with BMI and body fat percentage.
