Frequently Asked Questions

Which formula is most accurate?

No single formula is perfect for everyone. We average four respected formulas (Devine, Robinson, Miller, Hamwi) to reduce individual formula bias.

Does ideal weight account for muscle mass?

These formulas are based on height alone and don't account for muscle mass, frame size, or body composition — use alongside the Body Fat Calculator for a complete view.

Is being below my 'ideal weight' unhealthy?

Not necessarily. These are population-based estimates, not individual medical targets. Always consult a healthcare provider for personalised advice.
