The studio generates pages with a particular construction.

The page is made up of 3 distinct zones:

Page dimensions are defined in the "Page dimensions" tab of the PDF studio.

The studio offers predefined formats. Most are Ax, plus Letter format.

Choose the most suitable format from the drop-down list.

The page margins are important, as they're where the headers, footers and body are positioned.

Horizontal, "inner" and "outer" margins are named in relation to the fold of a book.

The inner margin is the one stuck to the fold of the book.

The outer margin is the one opposite the book's fold.

For a document that is not double-sided, the inner margin is always on the left of the page, the outer margin always on the right.

For a "double-sided" document, the inner margin is to the left of the page for an odd-numbered page and to the right of the page for an even-numbered page. Conversely, the outer margin is to the right of the page for an odd page and to the left of the page for an even page.

Larger inner margins can be advantageous for high-volume square-back printing. This means the text is not on the fold.

"Internal" and "external" margins define the horizontal origins and terminations of page zones, and therefore also their widths.

Page body, header and footer widths are not entered directly. These zones occupy the space left by the margins.

To find out the horizontal footprint of an area, simply subtract the page inner margin, the page outer margin and the page width. body width = page width - inner margin - outer margin header width = page width - inner margin - outer margin footer width = page width - inner margin - outer margin Example 1. Calculation of header and footer page widths Using the default Studio PDF settings, here's an example calculation. The default page size is A4 portrait. The page width is therefore 210mm The default page margin is 20mm. By default, the bottom margin of the page is 20mm. All you have to do is calculate 210 - 20 - 20 = 170 The body text will have a horizontal dimension of 170mm.

Vertical dimensions are described below.

Page body margins will define the origin and end of the page body area vertically. So also its height.

	The page body is positioned in relation to the page margins. Not in relation to the page itself.

To find out the height of the page body, simply subtract the page top margin, page bottom margin, body top margin and body bottom margin from the page height. body height = page height - page up margin - page down margin - body up margin - body down margin Example 2. Calculating page body height Using the default Studio PDF settings, here's an example calculation. The default page size is A4 portrait. The page height is therefore 297mm. The default internal margin is 20mm. The default external margin is 20mm. By default, the top margin of the body is 25mm. By default, the bottom margin of the body is 25mm. All you have to do is calculate 297 - 20 - 20 - 25 -25 = 207 The body text will have a vertical dimension of 207mm.

	In the design phase, the top margin of the body should be greater than the height of the header. Otherwise, the header will overlap the page body. Also, the lower body margin must be greater than the height of the footer. Otherwise, the page body will overlap the footer. See Height of header and footer

Figure 7. Page body margin edit fields

	The header and footer are positioned in relation to the page margins. Not in relation to the page itself.

Header and footer heights are entered directly in Studio PDF.

	When designing, the header height should be lower than the upper body margin. Otherwise, the header will overlap the page body. The footer height should also be less than the bottom margin of the body. Otherwise, the page body will overlap the footer. See Page body margins

The content and other elements of headers and footers can be set in the Header and footer menu.

A simple way of checking the page size configuration is to activate the measurement tools.

Once the measurement tools display is activated, the page body header and footer areas are framed by a black border.
