Sizes for Paper Screen and Tablet.
The sizes listed for screens tablets and paper can often be confusing with a number like A3, Tabloid or 8 1/2 X 11 given.
Here is a reference for most of the sizes in use today whether European (Metric) or USA and Canadian which is mixed but mostly in Imperial English or Inch sizes. To two of the tables I have added the diagonal size since it is often quoted (Some times to confuse you as to practical size.).
Sizes are in both Metric and the American/Canadian sizes. In reality Canadians most often use the ANSI sizes for paper.
The majority of the information on this page is available at:
The ISO sizes are in wide use in Canada and the United States of America. The most confusion of North Americans will be for the ISO or Metric styles -- so they are first.
The ISO sizes are in wide use in Canada and the United States of America.

US Paper Sizes

US Paper Sizes |
|||
|
North America, including the US, Canada and parts of Mexico, is the only area of the first world that doesn't use the ISO 216 standard paper sizes, instead they use Letter, Legal, Executive and Ledger/Tabloid paper sizes and those that have been formalised in ASME Y14.1M - Metric Drawing Sheet Size & Format. US Envelope Sizes are also non ISO 216 and are listed on this page. The following table gives the sizes in millimeters and inches of the Commonly used American paper sizes. |

ANSI Standard Paper Sizes |
||||||
|
ANSI (American National Standards Institute) defined a regular series of paper sizes based around the Letter (8.5" x 11") format, with this becoming the A sizes and larger sizes being B,C,D & E. Surprisingly these ANSI standard sizes were defined in 1995 well after the ISO standard sizes. ANSI A sized paper is commonly referred to as Letter and ANSI B as Ledger or Tabloid. |
||||||
|
Unlike the ISO standard sizes which have the single aspect ratio of 1:root2, ANSI standard sizes have two aspect ratios 1:1.2941 and 1:1.5455 which means that enlarging and reducing between the sizes is not as easy as with the ISO sizes and leaves wider margins on the enlarged/reduced document. |

Architectural Paper Sizes |
|||
|
North America also has a special series of paper sizes defined for architectural purposes, in general these have aspect ratios of 4:3 or 3:2. These aspect ratios are very similar to the aspect ratio used for computer screens. |

|
The following table gives details of the sizes for architectural paper. |
