Understanding Ideal Weight
Ideal weight is a range of body weight that is considered healthy for a person's height, gender, and frame size. While there's no single "perfect" weight for everyone, ideal weight ranges can serve as useful guidelines for maintaining good health and reducing the risk of weight-related health issues.
Factors Affecting Ideal Weight
Height
Taller individuals typically have higher ideal weight ranges due to increased bone and muscle mass.
Gender
Men generally have higher ideal weights than women of the same height due to differences in body composition.
Frame Size
People with larger frames can typically carry more weight healthily than those with smaller frames.
Common Ideal Weight Formulas
| Formula | Male Formula | Female Formula | Description |
|---|---|---|---|
| Hamwi | 106 + 6 * (height - 60) | 100 + 5 * (height - 60) | Developed in 1964, widely used in clinical settings |
| Devine | 110 + 5 * (height - 60) | 100 + 5 * (height - 60) | Created for medication dosing calculations |
| Robinson | 115 + 4.5 * (height - 60) | 100 + 4.5 * (height - 60) | Modified version of the Devine formula |
| Miller | 120 + 3.5 * (height - 60) | 100 + 3.5 * (height - 60) | Most recent formula, tends to give lower weights |

Frequently Asked Questions
What's the difference between ideal weight and BMI?
BMI (Body Mass Index) is a simple calculation based on height and weight, while ideal weight formulas take into account additional factors like gender and frame size. Ideal weight ranges provide more personalized recommendations than BMI alone.
How do I determine my frame size?
Frame size can be estimated by measuring your wrist circumference and comparing it to your height. Generally, a wrist circumference of less than 6.5 inches for men or 5.5 inches for women indicates a small frame, while measurements above 7.5 inches for men or 6.5 inches for women suggest a large frame.
Why do different formulas give different results?
Each formula was developed for different purposes and populations. The Hamwi formula was created for clinical use, while the Devine formula was designed for medication dosing. The Miller formula is more recent and tends to give lower weights. Using multiple formulas helps provide a more comprehensive range.
Should I aim for the lowest weight in my range?
Not necessarily. The healthiest weight for you depends on many factors, including your body composition, activity level, and overall health. It's often better to aim for a weight where you feel strong, energetic, and can maintain healthy habits long-term.
How often should I recalculate my ideal weight?
Your ideal weight range should be recalculated if your height changes significantly or if you're transitioning between life stages (e.g., adolescence to adulthood). Otherwise, the range remains relatively stable throughout adulthood.
