How it works
This calculator uses the Devine formula (1974), one of the most commonly cited ideal weight formulas. For men: Ideal Weight = 50 + 2.3 × (height in inches − 60). For women: Ideal Weight = 45.5 + 2.3 × (height in inches − 60).
A ±10% range is shown to account for individual variation in frame size and body composition. No single formula captures all factors, so use this as a starting reference alongside BMI and body fat percentage.
Practical example
A 175 cm (68.9 inches) male: Ideal Weight = 50 + 2.3 × 8.9 = 70.5 kg, with a range of 63.4 to 77.5 kg.
A 165 cm (65 inches) female: Ideal Weight = 45.5 + 2.3 × 5 = 57.0 kg, with a range of 51.3 to 62.7 kg. These are population averages — individual healthy weights vary with frame size and muscle mass.
Frequently asked questions
Is this medically accurate?
These are rough estimates. Body composition, muscle mass, and frame size all matter.
Should I aim for this exact weight?
Use it as a general reference. Consult a healthcare provider for personalized guidance.
Are there other formulas for ideal weight?
Yes. The Robinson, Miller, and Hamwi formulas are also commonly used. They all give slightly different results. The Devine formula is the most widely referenced.
Does this work for all body types?
No. People with large frames or significant muscle mass may have healthy weights above this range. Use body fat percentage and BMI together for a fuller picture.
