A4 Papers

A4 paper has a variety of uses. It's the paper size you'll find in most printers, as it's used for letters, forms and other basic documents. A4 is also the size used for magazine and catalog pages.
A4, although the most common, is just one standard paper size in a series of logical sizes. The ISO A-series contains eight different sizes. There is a constant height-to-width ratio throughout the series. Therefore, you can fold one size in half and the result will be the next size down. Each A-series paper size serves a different purpose in commercial printing. A0 is the largest size, used for large drawings and posters. The A6 size, measuring 148 x 105 mm, is used for postcards
