Ideal Weight Calculator
Calculate your optimal weight based on height and sex
⚖️ What is ideal weight
Ideal weight is an approximate healthy body-mass range for your height and sex. The calculator uses two popular formulas: Lorentz and Broca.
The result helps you see a typical healthy range, but it does not replace a medical assessment.
📐 Formulas
Lorentz
M: (Height − 100) − (Height − 150) / 4
F: (Height − 100) − (Height − 150) / 2
Broca
Base = Height − 100
Range: 90% to 110% of base
💡 Example
Male, height 175 cm:
- Lorentz: 75 − 6.25 = 68.8 kg
- Broca: 67.5–82.5 kg (±10% of 75 kg)
✅ Tips
- These formulas do not account for muscle mass, body type, or age.
- Results may be less accurate for people who are very tall or very short.
- Combine this with BMI and see a doctor if you plan to change your weight.
