Set mirror margins for facing pages

Use mirror margins to set up facing pages for double-sided documents, such as books or magazines. The margins of the left page are a mirror image of those on the right page. That is, the inside margins are the same width and the outside margins are the same width.

  1. Click Page Layout > Margins.

  2. Choose Mirrored.

Note: To change margin widths, click Custom Margins at the bottom of the Margins gallery. Enter new values in the Inside and Outside boxes.

Add a gutter margin for bound documents

A gutter margin adds extra space to the side margin, top margin, or inside margins of a document that you plan to bind. That helps ensure that text isn't obscured by the binding.

  1. Click Page Layout > Margins > Custom Margins.

  2. In the Gutter box, enter a width for the gutter margin.

  3. In the Gutter position box, click Left or Top.

Note: The Gutter position box is not available when you use the Mirror margins, 2 pages per sheet, or Book fold option. For those options, the gutter position is determined automatically

If you’re familiar with the desktop version of Word, you know you can use mirror margins to set up facing pages for double-sided documents, such as books or magazines. Word for the web preserves mirror margins already in your document, but it doesn’t yet provide a way to add them.

If you have the Word desktop application, click Open in Word to open your document in Word and create the mirror margins.

Then, follow the instructions for the desktop version of Word. When you’re done and you've saved the document, you can edit the document in Word for the web, and it will preserve the mirrored margins.
