Scientific Formulas for Calculating Ideal Body Weight: A Comprehensive Guide
Understanding the various scientific approaches to calculating ideal body weight is crucial for healthcare professionals and individuals alike. These evidence-based formulas have evolved through decades of medical research, each offering unique insights into optimal weight determination.
Hamwi Formula (1964)
Male: 48.0 kg + 2.7 kg per inch over 5 feet
Female: 45.5 kg + 2.2 kg per inch over 5 feet
Originally developed for medicinal dosage calculations, this formula considers:
- Gender-specific metabolic differences
- Height-based weight progression
- Basic body frame variations
Devine Formula (1974)
Male: 50.0 kg + 2.3 kg per inch over 5 feet
Female: 45.5 kg + 2.3 kg per inch over 5 feet
The most widely adopted formula, supported by extensive research, known for:
- Universal clinical application
- Balanced weight distribution
- Consistent results across populations
Robinson Formula (1983)
Male: 52 kg + 1.9 kg per inch over 5 feet
Female: 49 kg + 1.7 kg per inch over 5 feet
A refined version of the Devine formula, validated by modern studies, featuring:
- More conservative weight estimates
- Modern population considerations
- Refined height-weight ratios
Miller Formula (1983)
Male: 56.2 kg + 1.41 kg per inch over 5 feet
Female: 53.1 kg + 1.36 kg per inch over 5 feet
Based on comprehensive analysis, this formula accounts for:
- Contemporary body composition trends
- Adjusted metabolic factors
- Modern lifestyle considerations

Frequently Asked Questions About Ideal Weight
Why do different ideal weight calculators give different results?
Think of it like getting opinions from different doctors – each formula (Devine, Hamwi, etc.) was developed with slightly different research groups and purposes in mind. While they might vary a bit, they all provide a reasonable range to consider. That’s why we show you multiple results – it helps you understand the bigger picture rather than fixating on a single number.
Should I strictly follow the ideal weight calculator results?
Not necessarily! Think of these results as helpful guidelines rather than strict rules. Your ideal weight can vary based on factors the calculator can’t measure – like muscle mass, body type, and overall health. It’s best to use these results as a starting point for discussions with your healthcare provider about what’s healthy for your unique body.
Which formula is the most accurate for calculating ideal weight?
The Devine formula is generally considered the most widely accepted, but here’s the thing – there’s no one-size-fits-all answer. Each formula has its strengths. The Devine formula works well for most people, while the Miller formula might be better for modern body types. That’s why we recommend looking at the range of results rather than focusing on a single formula.
How often should I check my ideal weight?
No need to check daily! Your ideal weight range doesn’t change much unless there are significant changes in your height (which is unlikely for adults). It’s good to reassess every few months or when you’re starting a new health journey. Remember, sustainable health is a marathon, not a sprint!
What if I’m athletic or very muscular?
Great question! If you’re athletic or muscular, you might weigh more than these calculators suggest – and that’s perfectly fine! These formulas don’t account for muscle mass, which is heavier than fat. Athletes often fall outside these ranges while being perfectly healthy. Consider working with a sports nutritionist for more personalized guidance.
How can I reach my ideal weight in a healthy way?
The key is making sustainable changes – no crash diets! Start with small, manageable adjustments to your eating habits and physical activity. Aim for a balanced diet, regular exercise you enjoy, and adequate sleep. Most importantly, be patient with yourself. Healthy weight management typically means changes of 1-2 pounds per week. Remember to consult with healthcare providers before starting any new health program.
