Tool description
“Ideal body weight” formulas are reference estimates based on height and sex. They don’t account for body composition, age, or individual health factors. Use these numbers as rough guides, not strict targets.
How to use
- Select sex and units.
- Enter your height.
- Calculate to see multiple ideal weight estimates.
- Compare formulas rather than relying on a single number.
Why it’s useful
- Provides a quick reference range of estimates.
- Useful for planning discussions with healthcare professionals.
- Helps contextualize weight relative to height (roughly).
Use cases & interpretation
- General reference: treat results as a broad guideline.
- Fitness planning: prioritize performance and composition rather than a single scale number.
- Clinical context: clinicians may use IBW in dosing or estimates (varies by situation).
