What does "ideal weight" mean?

"Ideal weight" is a clinical estimate — originally used for medication dosing. Four mid-20th-century formulas are still widely used; the spread between them gives a range rather than a single number.

The four classic formulas

Devine (1974), Robinson (1983), Miller (1983), Hamwi (1964). All use a base weight at 60 in (152 cm) plus a per-inch increment above that.

BMI healthy range

Modern guidance often prefers WHO BMI 18.5–24.9 — a window rather than a single number. We show both.

Limitations & caveats

  • Assumes an average frame size — doesn't adjust for muscularity.
  • Originally for drug dosing, not body-image goals.
  • May be inaccurate for very short/tall individuals.
  • Not for children or pregnancy.
  • Pair with BMI, waist-to-height and body-fat %.
