Ideal Weight Calculator
Estimate your healthy ideal body weight using height and gender-based formulas. This calculator helps you understand the weight range commonly recommended for good health and optimal body composition.
How Ideal Weight Is Calculated?
Ideal weight is calculated using formulas that estimate a healthy weight range based on your height and gender. These methods provide a guideline for understanding what weight is typically associated with better health, though individual factors may vary. This calculator uses the Devine and Hamwi formulas — common clinical standards.
Common Ideal Weight Formulas: Devine Formula: Men: 50 kg + 2.3 kg for each inch over 5 ft Women: 45.5 kg + 2.3 kg for each inch over 5 ft Hamwi Formula: Men: 48 kg + 2.7 kg per inch over 5 ft Women: 45 kg + 2.2 kg per inch over 5 ft (Your calculator applies height in centimeters and adjusts using metric conversions.)

FAQ
What is ideal body weight?
Ideal body weight (IBW) represents a medically recommended weight range for your height and gender. It helps assess overall health and guides nutrition and fitness plans.
Is ideal weight the same for everyone of the same height?
No. Muscle mass, bone structure, genetics, and body composition influence your actual healthy weight. Ideal weight is a guideline, not a strict rule.
Which formula is most accurate?
Devine and Hamwi formulas are widely used in medical settings. They provide reasonable estimates, but athletic or muscular individuals may weigh more while still being healthy.
Why does gender affect ideal weight?
Men typically have higher muscle mass and bone density, leading to higher ideal weight ranges compared to women of the same height.
Can I use ideal weight to plan my fitness goals?
Yes, IBW is helpful for setting weight goals, but combining it with BMI, body fat percentage, and lifestyle factors gives a more complete picture.
