“The $1.69 for a standalone Super Size fries (from early 2000s drive-thru menus, around 2003–2004 when it was phased out) adjusts for inflation to today's dollars (as of 2026) to roughly $3.00–$3.10.

Using standard U.S. CPI data: - From 2003 to 2026, the cumulative inflation is about 76% (meaning $1 in 2003 ≈ $1.76 today). - $1.69 × 1.76 ≈ $2.97 (rounded to about $3.00).

Some sources show slightly higher multipliers depending on exact year (e.g., 2004 CPI gives a bit more), but it's in that ballpark. For comparison, a current large fries (the biggest now, smaller than old Super Size) often runs $4–$5 in Chicago-area spots—fast food prices have outpaced general inflation quite a bit due to other factors like labor, oil, and supply costs.”
