Ideal Body Weight Calculator
This calculator uses four well-known medical formulas to estimate your ideal body weight based on height and gender. Since each formula was developed using different population data, the results may vary. The average of all four gives a reasonable estimate.
The Formulas
- Devine (1974): Men: 50 + 2.3 × (height in inches − 60) | Women: 45.5 + 2.3 × (height in inches − 60)
- Robinson (1983): Men: 52 + 1.9 × (height in inches − 60) | Women: 49 + 1.7 × (height in inches − 60)
- Miller (1983): Men: 56.2 + 1.41 × (height in inches − 60) | Women: 53.1 + 1.36 × (height in inches − 60)
- Hamwi (1964): Men: 48 + 2.7 × (height in inches − 60) | Women: 45.5 + 2.2 × (height in inches − 60)
Frequently Asked Questions
Which ideal weight formula is best?
No single formula is universally best. The Devine formula is the most widely used by clinicians. The Miller formula is considered more accurate for taller individuals. It's best to use the average of multiple formulas as a general guideline rather than relying on any single one.
What is a healthy weight range for my height?
A healthy weight corresponds to a BMI between 18.5 and 24.9. For a given height, this translates to a specific weight range. The calculator shows this BMI-based range alongside the formula results so you can compare.
What are the limitations of ideal weight formulas?
These formulas were developed for general populations and don't account for muscle mass, bone density, body frame size, age-related changes, or individual health conditions. Athletes with high muscle mass may weigh more than the 'ideal' and still be perfectly healthy. Always consult a healthcare professional for personalized advice.
