Paper Sizes - commonly used in U.S. Offices

Office paper sizes as Letter, Legal, Tabloid and more

The ISO standard paper sizes are not commonly used in the United States and Canada. Instead paper formats like "Letter" (8.5 x 11 inches), "Legal" (8.5 x 14 inches), "Executive" (7 x 10 inches), and "Ledger/Tabloid" (11 x 17 inches) are widely used. The "Letter", "Legal", "Tabloid", and other formats (although not these names) are defined in the American National Standard ANSI X3.151.
