Ideal Weight Calculator

The Devine formula is the most commonly used in clinical settings, particularly for drug dosage calculations. However, no single formula is universally accurate. The Robinson and Miller formulas tend to give slightly higher estimates and may be more realistic for people with larger frames. Using all four formulas gives you a reasonable range to aim for.

The Devine formula (1974) calculates ideal body weight as follows: For men, 50 kg + 2.3 kg for each inch over 5 feet. For women, 45.5 kg + 2.3 kg for each inch over 5 feet. This formula was originally developed for calculating medication dosages but is widely used for general health assessment.

Yes, body frame size can affect your ideal weight. People with larger bone structures naturally weigh more. These formulas provide estimates for medium frames. If you have a large frame, aim for the higher end of the range, and for a small frame, aim for the lower end. Wrist circumference is one common way to estimate frame size.

Both tools have value. Ideal weight formulas give you a specific target weight based on height and gender, while BMI provides a range. Using both together gives a more complete picture. Neither accounts for muscle mass, so athletes and very muscular individuals may have a healthy weight above the calculated ideal.

If your weight differs significantly from the calculated ideal, consult a healthcare provider before making major changes. Gradual weight loss of 1-2 pounds per week is considered safe. Focus on overall health indicators like blood pressure, cholesterol, and energy levels rather than a single number on the scale.
