- Product
- Word
- Device & OS
- not provided
- Scenario
- Formatting a document for double-sided printing and book binding, requiring specific binding spaces and varied page numbering formats for the front matter and main body.
- Observed behavior
- To ensure text is not cut off during binding and to separate numbering styles, specific layout margins and section breaks must be properly applied.
Before adjusting margins for book binding, determine your physical binding method to know exactly how much gutter space is required.
Set Up Mirrored Margins and Gutter Space
Configure your document layout to automatically accommodate double-sided printing and binding.
Mirrored margins ensure that the left and right margins of double-sided pages mirror each other. The gutter adds necessary extra space so that text is not obscured when the pages are physically bound.
Navigate to the Layout tab on the top ribbon and click on Margins, then select Custom Margins at the bottom of the dropdown menu.
In the Page Setup dialog box, under the Pages section, select 'Mirror margins' from the 'Multiple pages' dropdown list.
In the Margins section of the same dialog, enter the required measurement in the 'Gutter' field. Click OK to apply the changes.

Apply Section Breaks for Independent Page Numbering
Separate your front matter from the main text to use Roman and Arabic numerals independently.

Frequently Asked Questions
Why does a blank page appear in my PDF but not in my document view?
The word processor automatically inserts a hidden blank even-numbered page when an Odd Page section break is used to ensure chapter 1 starts on a right-hand side during double-sided printing. This blank page often doesn't show in the standard Print Layout view but will appear in Print Preview or when exporting the file to PDF.
What is a gutter in document formatting?
A gutter adds extra space to the side margin or top margin of a document intended for physical binding. It ensures that the binding mechanism (such as spiral wires or glue) doesn't obscure the printed text on the page.
How do I unlink my headers and footers to change numbering?
After inserting a section break, double-click the header or footer area in the new section. Look for the 'Link to Previous' button in the Header & Footer toolbar and click it to turn it off. You can now insert a different page number format without affecting the previous sections.
