A complete guide to the most common paper sizes used in printing.

» International Paper Sizes.

A useful reference to the most common paper sizes used within the print industry.

Today, there are two widely used standards of paper sizes in use - the international standard and the North American sizes. The international paper size standard (ISO 216) is based on the German DIN 476 standard for paper sizes.

One of its great qualities is its scalability - the height of the sheet divided by the width is the square root of two. So folding any size sheet in half will make sure the two halves will always remain in the same proportion.
