This tool estimates your ideal body weight using four well-established medical formulas developed for clinical and fitness use. Results are averaged for a balanced, realistic estimate. This calculator draws on peer-reviewed, industry-standard formulas used by fitness professionals, dietitians and clinicians worldwide, translated into a fast, easy-to-use browser tool.
Tracking metrics like this over time — rather than relying on a single reading — gives you a much clearer picture of trends in your health and fitness journey. Use this tool regularly alongside our other calculators for a fuller picture of your overall wellbeing.

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