FAQ

What is ideal body weight?
Ideal body weight (IBW) is a statistical estimate of a healthy weight for a given height and gender. In medicine it is used to calculate drug dosages and assess nutritional status — not as a strict target.
Which formula should I use?
The Devine formula is the most commonly cited in clinical practice. For general wellness, the spread across all three formulas gives a useful reference range of a few kilograms.
Are these results accurate for everyone?
No formula fits everyone. These estimates do not account for muscle mass, bone density, or body fat distribution. Always consult a healthcare professional for personalised advice.
