Which ideal weight formula is most accurate?

No single formula is best for all people. The Devine formula is most commonly used in clinical drug dosing. Robinson and Miller were developed as refinements. The average of all three provides a reasonable reference range.

Why does ideal weight only use height and sex?

These formulas were developed as quick clinical tools, not precision fitness targets. They don't account for muscle mass, age, or bone density. A muscular athlete may be "above" ideal weight by these formulas yet be perfectly healthy.

How is ideal weight different from healthy BMI weight?

BMI-based healthy weight (18.5–24.9) gives a range; IBW formulas give a single number. Both are rough estimates. IBW is used more in pharmacology (medication dosing), while BMI is used more in population health.

Can I use this for children?

No — these formulas are validated for adults. Pediatric weight assessment uses age- and sex-specific growth charts from the CDC or WHO.

Ideal Weight Calculator

Quick answer: Enter your height and sex to see your ideal weight range from three validated formulas (Devine, Robinson, Miller) in both lbs and kg.

Ideal body weight (IBW) formulas give a reference range based on height and sex. This calculator runs three widely-cited formulas — Devine (1974, used in drug dosing), Robinson (1983), and Miller (1983) — and shows you the range and average. Note: IBW is not a personal health goal; it's a clinical reference range. Your actual healthy weight depends on muscle mass, bone density, and individual health markers.
