Here is a Table of The American Paper Sizes. These include Letter, Legal, Tabloid, Ledger, Junior Legal, Half Letter or Memo, Government Letter, and Government Legal. Standard Dimensions or Length and Width of American Paper in unit of measurements in mm (millimeter), cm (centimeter), and inch (inches).

The United States, Canada, and the Philippines primarily use a different system of paper sizes compared to the rest of the world. The current standard sizes are unique to those countries, although due to the size of the North American market and proliferation of both software and printing hardware from the region, other parts of the world have become increasingly familiar with these sizes (though not necessarily the paper itself). Some traditional North American inch-based sizes differ from the Imperial British sizes.

Letter, Legal and Ledger/Tabloid are by far the most commonly used of these for everyday activities, and the only ones included in Cascading Style Sheets (CSS). US paper sizes are currently standard in the United States and are the most commonly used formats at least in the Philippines, most of Mesoamerica and Chile. The latter use US Letter, but their Legal size is one inch shorter than its US equivalent.
