In Microsoft Word 2010, the advanced Margin options let you split each page in half, turning a horizontal page into two visually separate vertical pages. When you print the document and then fold the pages in half, they will form a booklet with left and right pages that you can thumb through as you would with a book. You can simply treat each half-page as a normal page, and Word will maintain a booklike format.
Step 1
Open the Microsoft Word file that you want to format as a booklet. Click the "Page Layout" tab on the ribbon.
