📚 Understanding Ideal Weight Formulas

Robinson Formula (1983)

Most widely used formula in clinical settings. Provides conservative estimates based on height and gender with good accuracy for general population.

Best for: General population
Accuracy: High for average builds
Note: May underestimate for athletes

Devine Formula (1974)

Originally developed for medical dosing calculations. Tends to give slightly higher weights than Robinson, often used in pharmaceutical contexts.

Best for: Medical applications
Accuracy: Good for clinical use
Note: Slightly higher estimates

Healthy BMI Range

Based on BMI 18.5-24.9, provides the widest range. Accounts for natural weight variation and different body compositions within healthy parameters.

Best for: Weight ranges
Accuracy: Good population health indicator
Note: May not suit muscular individuals

Body Frame Adjustments

Body frame size affects ideal weight. Small frames may carry less weight optimally, while large frames can carry more weight healthily.

Small Frame: -10% adjustment
Medium Frame: No adjustment
Large Frame: +10% adjustment

❓ Frequently Asked Questions

Which formula is most accurate?

The Robinson formula is most widely accepted in medical practice. However, using the average of all formulas often provides the most balanced estimate for general population.

What if I'm very muscular?

These formulas may underestimate ideal weight for athletes and very muscular individuals. Consider body fat percentage and lean mass instead of just weight.

How much weight variation is normal?

A 5-10 kg range within your ideal weight is completely normal and healthy. Daily weight can fluctuate 1-3 kg due to water, food, and hormones.

Should I aim for the exact ideal weight?

Focus on the healthy range rather than exact numbers. Your ideal weight is where you feel energetic, healthy, and can maintain long-term.
