In the American market ISO paper sizes are hardly used at all. The US-alternative to A3 is called Tabloid or Ledger (ANSI B) and measures 11 x 17″ or

The basis for the whole system is the A0 format which has an area of one square meter.

With an aspect ratio equal to the square root of two, a sheet of A0 paper ends up being x millimeters. Figuring out the dimensions of the subsequent paper sizes does not require any real mathematical strain since each ensuing size can be created by simply folding the paper in half with the crease parallel to the shortest sides.

If you do this with an A0 sheet of paper, the resulting dimensions will be x millimeters, or the A1 format. Take note that the height of A1 is equal to the width of A0.

The B series was brought into being to provide a wider range of paper sizes, where as the C series is used only for envelopes. The B paper sizes are a bit larger than their A series counterparts and are based on the geometric mean of two consecutive A series sheets.

The C series was introduced to provide an envelope with enough space for an A series sheet. The sizes of the A series fit in C series envelopes of the same number. That is, a sheet of A4 easily fits into a C4 envelope.

It is sensible to check the availability of envelopes before using non-standard paper sizes. Many unusual sizes are produced but there is no guarantee that an envelope is available off-the-shelf to fit a particular size. Some sizes are only manufactured in manilla, with windows, or in banker format.

For specialiality papers off-the-shelf envelopes sizes are usually restriced or non-existent. British and US sizes There are many British Standard paper sizes, whose dimensions are defined in inches, with evocative but puzzling names such as 'foolscap', 'post', 'pinched post', 'medium', 'royal, crown', 'quad crown' or 'double imperial'.

Although these sizes do not preserve their proportions when folded down as 'A' or 'B' sizes do, they do conform to a system of sorts based on folding in half. When a book is printed on a large sheet of paper folded once it is described as a 'folio', when the sheet is folded again it becomes a 'quarto' with four leaves, then an 'octavo', then a '16mo' and so on.

At first glance it seems relatively simple: If you place an A4- and Letter-sized paper one atop the other, with their top left-hand corners touching, the differences between the two sheets is obvious: Letter is wider than A4; A4 is longer than Letter.

So, for a design or layout to fit safely on both sheet sizes it must be no wider than A4 and no longer than Letter. Put another way, the limits for a design or layout which will fit safely on either page size are the width of an A4 sheet mm or 8.

A4 vs US Letter

The working area — mm by mm — is well within the bounds noted above. Fill the page with text, however, and a problem occurs if the document is sent to someone using Letter. The text still fits onto a single US Letter sheet, but it spills over the margins. When a Letter-user prints the file, the page will either not print properly because part of the text is placed into a non-printable portion of the sheet or will print on a second page.

The second result is better but neither is desirable and the second is dependent on too many uncontrollable variables in any event.

To avoid this problem, the only option for A4-users sharing documents with Letter-users is to increase their bottom margins to 45 mm. To again show rather than tell: With a standard 25 mm margin on all sides, a landscape layout that looks fine on Letter-sized paper encroaches into the danger area on A4: Add an extra 6 mm about 0.

The layouts presented in miniature above are deliberately simple but the suggested margin changes should work even with more complicated grid-based layouts.

Troubles can and will arise, however, with layouts built around a centre axis rather than one of the traditional grids. A layout built around only one central axis should still display and print acceptably across the paper-size divide with appropriate margin tweaks. A simple Victorian-style poster, for example, set up along the vertical axis in portrait mode:
