Frequently Asked Questions

No single formula applies to everyone. The BMI-based range (18.5–24.9 × height²) is widely used. Hamwi and Devine formulas are commonly used in clinical settings. Body composition matters more than any formula.

Yes. Men generally have higher muscle mass, so most formulas give men a higher ideal weight than women at the same height. The difference is typically 2–5 kg at the same height.

Ideal weight is a guideline, not a strict target. Factors like muscle mass, bone density, and age all affect what's healthy for you. Consult a doctor or registered dietitian for personalised advice.
