Ideal Weight Calculator: Find Your Healthy Weight Range
There’s No Single "Ideal" Weight
Multiple formulas exist to estimate ideal weight, and they give different numbers. That’s because "ideal" depends on your frame size, muscle mass, and body composition — not just height. Use these formulas as rough guides, not definitive targets.

Better Metrics Than Weight Alone
- BMI: Quick screen, but blind to body composition. Use the BMI calculator with caution.
- Body fat %: The gold standard. See the body fat guide.
- Waist-to-height ratio: Keep waist circumference below half your height for metabolic health
- Waist circumference: Men < 90 cm, Women < 80 cm (Indian standards)
Use the ideal weight calculator to see your range across all formulas and find a realistic target.
