Paper sizes

This list of the common American and European paper sizes includes the ISO standards, which are used globally. All dimensions are specified in inches, millimeters as well as PostScript points (1/72 inch, always rounded off).

This overview covers:

  • ISO page sizes – The ISO A series is the most frequently used page measurement standard. It includes the DIN A4 format. The ISO B sizes are used for poster printing while ISO C is meant for envelopes. The SRA standard defines press sheet sizes and is used in the printing industry.
  • American paper size dimensions – such as ‘Letter’, ‘Legal’ and the ANSI series.
  • English sheet sizes – with a focus on formats for writing paper and book printing.

ISO A paper sizes

The A-series consists of a logical set of paper sizes that are defined by the ISO 216 standard. The largest size (A0) measures one square meter. The height/width ratio remains constant (1:1.41) for all sizes. This means you get the A1 size by folding an A0 paper in two along its shortest side. Then fold the A1 size in two to get an A2 size paper, and so on… A-sizes are used to define the finished paper size in commercial printing: A4 is for office documents, A5 is for notepads and A6 is for postcards.

This drawing illustrates the principle behind the ISO A series:

A0, A1, A2, A3, A4, A5, A6, A7 and A8

ISO B paper sizes

The same logic from the A-sizes also applies for the B-series, except here the starting point was the dimension of one of the sides, which starts at 1 meter. B-sizes are often used for posters.

American paper sizes

The US and Canada do not use the international standards but instead rely on the paper sizes below. The ANSI standard was added in 1995 to create a set of sizes that are based on shared dimensions. It lacks however the consistent aspect ratio of the ISO A-series.

English paper sizes (writing papers)

The English nowadays use the A-sizes for office and general use. I have no idea whether many of these definitions are still in use today. Imperial and half-imperial still seem to be widely used by artists.

76 Responses to “Paper sizes”

  1. Lars says:

    Great summary for the “non-initiated” – thanks!

  2. George Rivas says:

    I take issue with your flip comment that there is no apparent logic behind US paper sizes. The American Society for Testing and Materials sets these sizes and they are very logical and easy to remember without resorting to references (see below). Some of these sizes have also picked up synonyms such as “letter” which, I would argue, are no more illogical than British terms such as “foolscap”.
    A size is the functional equivalent to UK A4 and is 8.5in by 11 inches. As the letters increase the short dimension is doubled. E.g: B size is 17×11 inches (roughly A3 – also called ledger), C size is 17×22 inches, D size is 34×22, and E size (typically a ‘full-size” engineering drawing) is 34×44.
    Special paper sizes such as executive, legal, etc. are marketing names developed by stationary companies and immortalized by the print drivers installed on your computer.
    I would have expected more research from a professional printing site.

  3. Laurens says:

    Ouch, I never realized people could be this sensitive about paper sizes. Thanks for the explanation though, which is very informative! I have changed that line of text on the page.

    As for this site being a professional site: it isn’t. I see it as my web-enabled notebook. I can only guarantee that visitors get more than what they paid for :-) … but I acknowledge that this is no excuse for making mistakes.

    Again: thanks for the feedback!

  4. scooter says:

    Whoa… tell me about it! Sounds like a genuine paper expert there. Very helpful none the less. Thanks!!

  5. Alistair says:

    While I agree there really is some logic behind the US paper sizes I suggest the gentleman taking umbrage be a little more sensitive to the US approach to ignoring international standards in this and many related areas.

    The US continues to use measurement basis that the rest of the world largely abandoned (except for specific special cases) a while ago. Such changes are obviously not trivial for a population to embrace…but people do quickly adapt. His example of foolscap is a case in point, it is an archaic size and very difficult to find in the UK…the ISO A sizes having been adopted years ago.

    It is public record that the US was the last major player to accept SI as legal remarkably recently, and remains the last to not require it on packaging and the like.

    The US even insists on a different system of maritime navigation marks whilst everyone else not dominated by big brother uses a different internationally agreed approach.

    It should therefore be no surprise if the raison d’etre behind the US approach is less than widely understood outside the US.

    I am from the UK but have lived and worked in the US for over decade now. I know from personal experience how unnecessary these differences really are…and a little bit of flippancy in the face of such national arrogance seems totally appropriate to me…even if it was unintentional in this case.

  6. Ron Spicer says:

    I do not mind the size issue US and others. To each there own place and size. But I do mind not have copiers with preprogramed enlarge and reduction setting for standards. The common US are list or the common ISO are listed but why not have ISO to US and US to ISO the V and H ratios could be preset and ready for use.

  8. ML Jennings says:

    Thank you for the information found on this site. It has been a big help – I have printed it out and put it next to our copier for the staff to see. Knowing the exact sizes of the various papers is a great help.

  9. Samantha Leith says:

    Your information is ok. but can get a bit more stuff cause i still did not find wat i was looking for. I was looking for popular paper sizes but didnt get it.

    • Laurens says:

      I think it is difficult to list how popular certain paper sizes are. Obviously this depends on the intended usage but there are also big regional differences. Most of Europe sticks to ‘A4′ for letters and general office printing but you won’t find this size much in the US. If anyone has a list, please post a link!

  10. Linda Setzer says:

    It has taken me 70 years to get curious enough about sizes of paper and envelopes and paper. Your site has fulfilled that curiosity most admirably! Thank you.

  11. Andrea Grififths says:

    WHat is a livre demi-poche? And what size is it?
    Thanks

    • Laurens says:

      I cannot find a definition for it either. A ‘livre de poche’ is a pocketbook, typically 130×190 mm. ‘Demi-poche’ could be a half-size version but I cannot find any dimensions for it. I’ll ask one of my French colleagues, maybe they know.

  14. Ian Southen says:

    Hi

    Great list thanks.

    Can you help with paper sizes for music. I believe they are quite different.

  15. Katie Pierce says:

    Hi, I am trying to find out what paper size for a publication that folds over and is (when folded) letter size or 8.5×11? Do you know what software and printers to use for this size paper?

    • Laurens says:

      If you want to simply fold a page along the shortest side to end up with a letter size document, you need to use a tabloid size page (11×17″). If it is a more complex folding scheme you are after, such as a gatefold or one or two folding panels, then each panel needs to be smaller to compensate for inaccuracies in folding and cutting. If this isn’t done the edge of the paper will crease when the piece is folded. I think panels that are 1/16″ of an inch less wide is the general recommendation but it is better to consult with your printer.
      The regular layout applications like Adobe InDesign, QuarkXpress,… are used for designing folded documents. Typically thin lines in the bleed area indicate where the document should be folded.

      This is most likely very too late for you. However, I’m trying to learn the difference between Hagaki, Wallet, Passport, l, & 2L for a personal photo collage project I’m working on. The L is 3 1/2 x 5 The 2L is 5×7.01 like a post card w/ a borderless photo.

    • Star Kinnison says:

      Duncan, this is most likely way too late for your answer. I’m working on a kind of a collage photo like project. I’m throwing together a bunch of different pics together on an 8.5×11 photo paper (A Letter). During tips of how to put multi pics on 8.5×11 , it gave a break down of how many different size pics can fit on this size. I ran into the Passport, Wallet, Hagaki, L, & 2L. I’ve been googling the difference between all these sorts of papers. The 2L (or 5R) is 5×7.01 like a post card borderless photo. The L (3R) is 3.5×5 of Photographic Paper.

  52. Linda says:

    I wanted to change Letter to A4, but then I had to choose from a new dropdown: A4 1/4, A4 1/3. What is that?

  53. Tracey says:

    Regarding your observation: American paper sizes lacks the consistent aspect ratio of the ISO A-series.
    You are absolutely correct!!!

    That is because in the decades prior to Personal Computer, the US Standard “Letter” Sizes were for designed for the draftsman: the kind-a guy sitting at the angled desk with the only electrical device in sight would be the light bulb (he EVEN had to manually sharpen his own pencils).

    Size A is 8-1/2″ x 11″ inches (how they determined that I do NOT know).
    After that (B,C,D,etc.) sizes either doubled in width and/or height as needed for drafting (the biggest ones were nick-named bed sheets).
    At one time I the task of printing out blue prints stored on microfilm embedded in punch cards: I think F is the largest size I remember seeing on a regular basis but I am almost positive that they go larger than that (I mean in the US Standard Letter Sizes).
    Most of the blue prints stored on microfilm that I saw were of size D or E.

    BTW You can add 2 additional US Commercial Standard Paper Sizes (mostly for historical purposes):

    #1 Statement size: 8-1/2 by 5.5 (also known as the half sheet)
    As a kid I always thought that the half-sheet was just a letter size sheet of paper physically torn in half.
    I recently cleaned out an office that had numerous forms printed in the 1970′s.
    The forms that were not letter size were statement size (exactly half the size of the Letter-Size sheet of paper :-)

    #2 US Standard Fan-Fold (aka green bar): 14-7/8″ by 11″ – These are/were for the wide pin-feed (teletype / industrial / factory) printers.

    MY original post on this topic was ‘ Why is it that UK bank statements (and some other official documents), use paper that measures 300mm X 210mm – i.e. just 3mm longer than standard A4? It matters. because it won’t fit in a standard copier feed tray.

    Good post. I be taught something on completely different blogs everyday. It’s going to all the time be stimulating to read content material materials from other writers and comply with just a bit something from their blog.

      You don’t seem to have a problem with a paper size, you struggle with a printer driver or export settings. I can’t help with those.

    You mention that you’re not sure what the ISO D sizes are for – they are envelope sizes for the B series, much like C are envelope sizes for A.
