⚖️ Ideal Body Size Calculator
📐 About this advanced tool: The ideal body size calculator integrates globally accepted formulas (Devine, Robinson, Miller, Hamwi) combined with body frame adjustment and healthy BMI range. It provides personalized ideal weight targets for both men and women. Unlike generic tools, this advanced calculator visualizes different medical standards, frame effect, and current weight comparison — used worldwide by clinicians, fitness experts, and health-aware individuals.
Formulas differ by sex (hormonal & body composition standards).

📈 Ideal weight comparison (clinical formulas vs BMI range)
🔍 Explanation of each factor (USA & worldwide standards)
• Gender: Hormonal & muscular differences – Devine, Robinson, Miller formulas use distinct baselines.
• Height: Metric/imperial conversion; all formulas reference inches above 5 feet (common in clinical practice).
• Body Frame: Small/Large frame modifies ideal weight ±10% (based on wrist circumference & elbow breadth – NIH/WHO compatible).
• BMI Range: 18.5–24.9 (WHO global standard) – no frame adjustment, gives healthy weight interval.
• Current Weight Delta: shows surplus/deficit vs Devine ideal (most cited for medication dosing).
💡 All results combine international medical reference data (USA, EU, Asia) & are unit-agnostic.
