Calculate your ideal weight using our comprehensive ideal weight calculator 2026. Our calculator uses four scientific formulas (Robinson, Miller, Devine, Hamwi) and averages them to provide the most accurate ideal weight recommendation. Get personalized weight range based on your height, gender, and body frame size.

How Ideal Weight is Calculated

Ideal weight is calculated using multiple scientific formulas that consider height and gender. Our calculator uses four well-established formulas:

• Robinson Formula (1983): Widely used and gender-specific formula developed by Dr. Robinson
• Miller Formula: Simpler formula for quick ideal weight calculation
• Devin Formula: Traditional medical formula used in healthcare settings
• Hamwi Formula: Comprehensive method that provides detailed calculations

The calculator averages all four formulas and adjusts for body frame size (Small: -10%, Medium: ±0%, Large: +10%) to provide the most accurate ideal weight recommendation.

Understanding Body Frame Size

Body frame size is determined by wrist circumference relative to height:

• Small Frame: Wrist < 6.5 inches (men) or < 5.5 inches (women) - Reduces ideal weight by 10%
• Medium Frame: Wrist 6.5-7.5 inches (men) or 5.5-6.5 inches (women) - Standard weight (±0%)
• Large Frame: Wrist > 7.5 inches (men) or > 6.5 inches (women) - Increases ideal weight by 10%
