How this calculator works
This calculator estimates ideal body weight using the Devine formula and shows a practical range around the estimate. Enter height and sex to see the estimated ideal weight and a range. Use it for weight goal setting, health reference, and understanding formula-based estimates. The key inputs are height and sex. The output is the estimated ideal weight and a practical 10% range. Real-world applications include weight management, health reference, fitness planning, and goal setting. The calculator uses the Devine formula, which is a widely referenced ideal weight formula. It shows a range because a single number is less useful than a practical range that accounts for real body variation. There is no one ideal weight for everyone. Frame size, muscle mass, health history, and personal goals matter. Athletes may find formula-based ideal weight less useful because muscle mass can raise weight without indicating poor health.
