on a larger piece of paper or film to accommodate any printer’s marks or the bleed and slug areas.
The list of paper sizes available to InDesign comes from the PPD (PostScript printers) or from the printer driver (non-PostScript printers). If the
printer and PPD you’ve chosen for PostScript printing support custom paper sizes, you’ll see a Custom option in the Paper Size menu.
Most imagesetters can accommodate regular paper sizes, such as letter and tabloid, as well as transverse orientation, where the regular page size
is rotated 90° when printed. The transverse orientation is often a more efficient use of imagesetter media.
Page size and orientations for imagesetters
A. Letter (tall orientation) B. Custom page size (tall orientation) C. Letter (transverse orientation)
Paper sizes are listed by familiar names (such as Letter). The dimensions define the limits of the imageable area—the total paper size, less any
unprintable border used by the printer or imagesetter. Most laser printers cannot print to the exact edge of a page.
If you select a different paper size (for example, if you change from Letter to Legal), the document is rescaled in the preview window. The preview
window displays the entire imageable area of the selected page; when the preview size is changed, the preview window automatically rescales to
include the imageable area.
The imageable area will vary by PPD file, even for the same paper size (for example, Letter), because different printers and imagesetters
define the sizes of their imageable areas differently.

The preview in the lower-left area of the Print dialog box indicates whether you have enough space to include all printer’s marks and the
bleed and slug areas.
Specify paper size and orientation
1. Choose File > Print.
2. In the Setup area of the Print dialog box, choose an option in the Paper Size menu.
Make sure that your paper size is large enough to contain your document, the bleed and slug areas (if included), and any printer’s marks. To
conserve imagesetter film or paper, however, select the smallest paper size that will accommodate your document and the necessary
printing information.
3. Click an Orientation button to rotate the document on the media.
