Ideal Body Weight Calculator
Ideal Body Weight (IBW) is an estimation of what a person might weigh if they were at a “healthy” weight for their height. Several formulas exist to calculate IBW, and they can yield different results.
This calculator uses the following common formulas (weights are based on inches over 5 feet height):
- Devine Formula (1974):
- Men: 50 kg + 2.3 kg/inch over 5 ft
- Women: 45.5 kg + 2.3 kg/inch over 5 ft
- Robinson Formula (1983):
- Men: 52 kg + 1.9 kg/inch over 5 ft
- Women: 49 kg + 1.7 kg/inch over 5 ft
- Miller Formula (1983):
- Men: 56.2 kg + 1.41 kg/inch over 5 ft
- Women: 53.1 kg + 1.36 kg/inch over 5 ft
- Hamwi Formula (1964):
- Men: 48 kg + 2.7 kg/inch over 5 ft
- Women: 45.5 kg + 2.2 kg/inch over 5 ft
Note: These formulas are primarily designed for adults. Results may vary, and they do not account for factors like frame size, muscle mass, or age in detail.
Important: IBW calculations are estimates and should not replace professional medical advice. Consult a healthcare provider for personalized health and weight assessments.

Understanding Your Results:
- The formulas provide a range of estimates. Differences are common due to variations in their development and assumptions.
- These values are theoretical and serve as a general guideline, not a strict target.
- Focus on overall health, including diet, exercise, and body composition, rather than a single number.
- If your height is below 5 feet (152.4 cm), these formulas may be less accurate or not applicable.
