Ideal Weight Calculator
An ideal weight calculator is a health utility that provides a target weight range based on your height, gender, and age. While "Ideal Weight" is a subjective term that depends on muscle mass and body composition, mathematical formulas like the Devine, Miller, and Robinson equations provide a useful baseline for medical and nutritional planning. These formulas were originally developed to help doctors determine appropriate medication dosages, but they are now widely used as a general guide for healthy living. Our calculator provides multiple perspectives to help you find a sustainable and healthy target for your unique body type.
How to Use Ideal Weight Calculator Step by Step
- Enter your "Current Height" - provide your stature in cm or ft/in.
- Select "Gender" - biological differences affect bone density and muscle-to-fat ratios.
- Enter "Age" (Optional) - some formulas adjust for the natural changes in body mass over time.
- Click "Calculate" - the tool will apply four major medical formulas.
- Review the "Average Ideal Weight" - see the consensus across different scientific models.
- Check the "Healthy BMI Range" - compare your results with the World Health Organization (WHO) standards.
Ideal Weight Calculator Formula Explained
The weight allocated for the first 5 feet (60 inches) of height.
The additional weight added for every inch above 5 feet.
The Devine formula was developed in 1974 by Dr. B.J. Devine - originally as a method for calculating medication dosages, not as a definitive measure of healthy weight. It and similar formulas (Hamwi, Robinson, Miller) remain useful as reference points, but 'ideal weight' is not a single number. Healthy weight ranges depend on body composition, muscle mass, frame size, ethnicity, and individual health factors. The U.S. National Institutes of Health considers a BMI of 18.5-24.9 a 'healthy weight range' for most adults, but stresses that weight goals are best discussed with a healthcare provider.

The Devine formula estimates 172 lbs; healthy weight ranges vary by individual
Example 2 - Female Health Baseline
Finding the target weight for a 5'4" woman.
Gender: Female · Height: 5'4" (163cm)

Common Ideal Weight Calculator Mistakes to Avoid
Ignoring muscle mass. If you are a bodybuilder, your "Ideal Weight" will be much higher than these formulas predict.

Obsessing over reaching the "Ideal" number while ignoring other health markers like energy levels, blood pressure, and strength.
