The MediaBox is the largest page box in a PDF.If a CropBox is present, the ArtBox, TrimBox, and BleedBox need to extend beyond its boundaries. The ArtBox or TrimBox cannot be larger than the BleedBox. PDF/X-4 files need, next to the MediaBox, a TrimBox or an ArtBox, but not both.PDF/X-1a and PDF/X-3 compliant files need to include the MediaBox, TrimBox, and BleedBox.The above rule is not true for the PDF/X file formats:.

All the other page boxes do not necessarily have to be present in regular PDF files.

A PDF always has a MediaBox definition.

That may seem logical but artwork is not always rectangular: a PDF can represent an oval label or the foldout of a cardboard box.

The page boxes are always rectangular.

Each page in a PDF can have different sizes for the various page boxes.

It shows that in Acrobat the MediaBox is highlighted with a magenta rectangle, the BleedBox with a cyan one while dark blue is used for the TrimBox. This PDF was then opened in Acrobat Pro DC, where I took a screenshot. The A4 page shown below was created in Indesign with 5 mm bleed and exported to a PDF/x-4 file using GWG 2015 settings.

How to see the presence and size of the page boxes The ArtBox can be used to indicate the dimensions of this part of the page. The area where it is safe to place graphic elements is called the safety zone or text safe area. In book design, there is also a margin where you cannot put text because the binding might make it difficult to read text that is too close to the spine. If the poster is not mounted properly, this could cause that text or logo to disappear behind the frame of the lightbox. When creating a poster that will be placed in a lightbox, the designer must make sure text and logos arenвЂ™t positioned too close to the edge.

A more common use of the ArtBox is as a means to indicate the safety zone.

This allows you to place that PDF on another page but only use the area covered by the advert.

On a PDF page that contains an advertisement, the ArtBox can be used to define the location of that ad.

It is never used for that but can be handy in a few cases: It was originally added to indicate the area covered by the artwork of the page.

The ArtBox is a bit of a special case.

By default, the BleedBox equals the CropBox.

Most prepress systems allow you to define the amount of bleed yourself and ignore the BleedBox. It is nice to know the size of the BleedBox but it isnвЂ™t that important in graphic arts. Usually the BleedBox is 3 to 5 millimeters larger than the TrimBox.

The BleedBox determines the region to which the page contents needs to be clipped when output in a production environment.

By default, the TrimBox equals the CropBox. The imposition programs and workflows that I know all use the TrimBox as the basis for positioning pages on a press sheet. Contrary to the CropBox, the TrimBox is very important because it defines the actual page size that gets printed.

The TrimBox defines the intended dimensions of the finished page.

The GWG industry association recommends not to use it at all. For prepress use, the CropBox is pretty irrelevant. So if a PDF contains a CropBox definition, Acrobat uses it for screen display and printing.

The CropBox defines the region that the PDF viewer application is expected to display or print.

This means that PDF files used in graphic arts usually have a MediaBox which is larger then the trimmed page size.

For prepress use, this is not the case as we prefer our pages to be defined slightly oversized so that we can see the bleed (Images or other elements touching an outer edge of a printed page need to extend beyond the edge of the paper to compensate for inaccuracies in trimming the page), the crop marks and useful information such as the file name or the date and time when the file was created. For the average user, this probably equals the actual page size.

The MediaBox is used to specify the width and height of the page.

These are called the boundary boxes or page boxes: There can in fact be up to 5 different definitions in a PDF that relate to the size of its pages. That page size definition is not as straightforward as you might think. It also contains a definition of the physical size of those pages. A PDF describes the content and appearance of one or more pages.
