Estimate your ideal body weight range based on gender, height, and body frame using multiple medical formulas
This calculator estimates your ideal body weight using four different medical formulas: Devine, Robinson, Miller, and Hamwi. These formulas were developed for medical dosage calculations and provide a useful reference range. The results also include the healthy BMI range (18.5-25) for comparison.
The Devine formula is the most widely used in clinical settings, particularly for medication dosing. However, no single formula is perfectly accurate for everyone. The Robinson formula tends to give lower values, while Hamwi gives higher values. Use the range across formulas and your BMI range as a guide.
Yes, people with larger frames (wider bone structure) typically weigh more at the same height. The formulas adjust by adding or subtracting approximately 10% based on frame size. You can estimate your frame size by measuring your wrist circumference relative to your height.
