Why Use an Ideal Weight Calculator?
Understanding your Ideal Body Weight (IBW) can be a helpful metric for setting fitness goals. Unlike a simple scale reading, IBW formulas take your height and gender into account to provide a range of healthy weights traditionally used in settings for dosage calculations and health assessments.
The Formulas We Use
This calculator aggregates results from five well-known medical formulas to give you a comprehensive range:
- Devine (1974): The most widely used formula for medical dosages.
- Hamwi (1964): Often used in dietary settings for quick estimations.
- Miller (1983) & Robinson (1983): Refined variations that adjust calculations based on empirical data.
- Peterson (2016): A modern formula designed to be more accurate across a wider range of heights.
User Reviews
"I love seeing the range from different formulas. It gives me a realistic
target zone rather than just one number."
"Very comprehensive and easy to use. The dark mode is great on eyes."
Frequently Asked Questions
Does this calculate BMI?
No, BMI is a separate calculation based purely on mass/height squared. This tool calculates Ideal
Body Weight based on gender-specific linear equations.
Why do the formulas give different results?
Each formula was developed based on different population data sets and medical goals over the
decades. Seeing multiple results gives you a better "healthy range" perspective.
