How Ideal Weight Is Calculated
There's no single "ideal weight" — it depends on many factors. This calculator uses multiple established formulas, each developed from different research populations. The results give a range that serves as a general guideline.
Formulas Used
Devine: Male: 50 + 2.3 × (inches over 60) kg | Female: 45.5 + 2.3 × (inches over 60) kg
Robinson: Male: 52 + 1.9 × (inches over 60) kg | Female: 49 + 1.7 × (inches over 60) kg
Miller: Male: 56.2 + 1.41 × (inches over 60) kg | Female: 53.1 + 1.36 × (inches over 60) kg
Hamwi: Male: 48 + 2.7 × (inches over 60) kg | Female: 45.5 + 2.2 × (inches over 60) kg
Limitations
- These formulas don't account for muscle mass, bone density, or body composition
- Athletes and muscular people may weigh more than "ideal" and still be very healthy
- The formulas were developed primarily from Caucasian populations
- Individual factors like genetics, age, and frame size matter
Frequently Asked Questions
Which formula is most accurate? The Devine formula is most widely used in clinical settings. However, the healthy BMI range (18.5-24.9) is generally considered the best overall reference.
Is BMI a good measure? BMI is a useful screening tool but has limitations. It doesn't distinguish muscle from fat. Use it alongside body fat percentage for a more complete picture.
What if I'm outside the range? These are guidelines, not absolute targets. Focus on overall health markers: blood pressure, blood sugar, cholesterol, and how you feel.
