Ideal Weight Calculator Information
What is Ideal Weight?
Ideal weight is an estimated healthy weight range based on your height, gender, and body frame size. It's a guideline for maintaining good health and fitness, not a strict target. Understanding your ideal weight can help you set realistic health and fitness goals.
- Multiple formulas: Robinson, Miller, Devine, and Hamwi methods
- Considers height, gender, and frame size
- Provides a healthy weight range, not a single number
- Guideline for health, not a strict requirement
How Ideal Weight is Calculated
The Ideal Weight Calculator uses multiple formulas to provide a comprehensive range. Each formula has been developed based on different populations and research studies, giving you various perspectives on healthy weight ranges.
- Base Weight = Starting weight based on gender and height
- Height Adjustment = Additional weight per inch above base height
- Frame Size Multiplier = Adjustment for small (0.9), medium (1.0), or large (1.1) frame
- Ideal Weight = Estimated healthy weight in pounds or kilograms
Example: 5 feet 8 inches male with medium frame
Ideal Weight Range: 130-142 lbs
Popular Ideal Weight Formulas
Robinson Formula (1983)
Most commonly used formula, based on extensive research and widely accepted in medical practice.
Miller Formula (1983)
Similar to Robinson but with slight adjustments, often used as an alternative reference.
Devine Formula (1974)
Originally developed for medication dosing, now commonly used for ideal weight estimation.
Hamwi Formula (1964)
One of the older formulas, still referenced in medical literature and practice.
Frame Size Determination
Frame size affects your ideal weight range. Here's how to determine your frame size:
Small Frame
- Wrist circumference < 6.5" (men)
- Wrist circumference < 6" (women)
- Narrow shoulders and hips
- Multiply ideal weight by 0.9
Medium Frame
- Wrist circumference 6.5-7.5" (men)
- Wrist circumference 6-6.5" (women)
- Proportional build
- Use ideal weight as calculated
Large Frame
- Wrist circumference > 7.5" (men)
- Wrist circumference > 6.5" (women)
- Broad shoulders and hips
- Multiply ideal weight by 1.1
