Ideal Weight Calculator

Determining your ideal weight is more complex than it might seem. Different scientific formulas have been developed over the decades, each with its own approach and considerations. Our calculator uses four well-established formulas to give you a comprehensive view of your ideal weight range.

The Four Scientific Formulas

1. Robinson Formula (1983)

Developed by J.D. Robinson, this formula is widely used in clinical settings and provides a good balance for most body types.

2. Miller Formula (1983)

Dr. Miller's formula tends to give slightly higher weights and is often preferred for athletic builds.

3. Devine Formula (1974)

One of the most commonly used formulas in medical practice, originally developed for drug dosage calculations.

4. Hamwi Formula (1964)

The oldest formula in our calculator, developed by Dr. G.J. Hamwi for quick clinical assessments.

BMI-Based Healthy Weight Range

In addition to the formula-based calculations, we also provide the healthy weight range based on Body Mass Index (BMI). A BMI between 18.5 and 24.9 is considered normal weight by the World Health Organization.

Factors That Influence Ideal Weight

• Body Frame Size: Small, medium, or large frame affects ideal weight
• Muscle Mass: Athletes may weigh more due to muscle density
• Age: Metabolism and body composition change with age
• Bone Density: Varies between individuals and ethnicities
• Overall Health: Medical conditions can affect optimal weight
• Lifestyle: Activity level and occupation influence ideal weight

Limitations of Ideal Weight Formulas

While these formulas provide useful guidelines, they have limitations:

• They don't account for body composition (muscle vs. fat)
• They may not be accurate for very tall or very short individuals
• They don't consider individual health conditions
• They're based on population averages, not individual needs
