I get asked about once a month how to set a single page of a Word document to landscape mode, while leaving the rest of the document in portrait. It should be easy and obvious. In Word 2007, it’s not difficult, but it’s anything but obvious.
First, go to the end of the page just prior to the page you want to turn to landscape mode (longways or sideways). Click on Page Layout, then click on Breaks. From that dropdown, scroll to Section Breaks, and select Next Page. Then go to the end of the section you want switched to landscape and do the same thing–click on Breaks, scroll to Section Breaks, and select Next Page. Now click the tiny little arrow in the lower-right hand portion of the Page Setup thingamajig, which brings up the old-fashioned Page Setup dialog. Select Landscape under Orientation, then at the bottom of the dialog box where it says Apply To, select This Section. Click OK.
Congratulations. Now part of your document is in landscape mode.
Chances are you have some extra blank pages in the document now too. To clean those up, go to the pages immediately preceding the extra blank pages, move to the end, and delete empty lines until those extra pages go away.
If there’s an easy way to change one page to landscape without creating those blank pages, I haven’t found it. Fortunately it only takes a few seconds to get rid of them, at least.
