Microsoft Word makes it as quick as a click to get started on a new document, as the default page size opens to an 8.5 inch by 11 inch page replica. Whether you created a document from that size and need to resize it to fit your printer or you’ve inherited an older file and want to resize it to fit your marketing materials, Word lets you resize a document to fit outside the box. Choose from one of Word’s included template sizes or apply your own precision formatting to suit Word exactly to your dimension requirements.

Launch the Office product, such as Microsoft Word. Click the “File” tab and open the document to resize. If you’ve recently opened it, the file name may already appear in the “Recent” pane.

Click the “Page Layout” tab and then click the “Size” button on the ribbon.

Click one of the new page size options, or click “More Paper Sizes” and click through the options on the “Page Setup” window. For a custom page size, scroll the “Paper Size” menu to “Custom Size.”


Resizing a document will cause significant changes to its layout and flow. Going from a larger page to a smaller page will cause your document to gain pages, whereas increasing the size of your page will reduce the number of pages. This may become an issue when you’re replying to a Request for Proposal, for example, which has strict requirements on page count and page size. It’s always a good idea to scroll through your document after resizing to check the new page breaks, flow and image layout.


These instructions apply to Microsoft Office 2013. Earlier or later versions of the software may present several differences.
