How to Double Space in MS Word
Creating a document with double spacing offers a few benefits. The text may be easier to read when it's not bunched up and people who are line editing will have room to mark up your text directly above or below the actual words, rather than in the margins. Whether you're creating a new Microsoft Word document or want to double-space an existing one, increase your spacing with just a couple of clicks in Word.
Open Microsoft Word. To double-space an existing document, click the "File" tab, click "Open" and browse to the Word document. Double-click the file name and the Word document opens in a new Word window.
Highlight the text to double-space, such as a paragraph or page. To double-space your entire document, click the "Select" button on the very right side of the ribbon/toolbar at the top of the screen and click "Select All".
Right-click the highlighted area and select "Paragraph". Pull down the "Line spacing" option and select "Double". Click the "OK" button and the spacing changes in all of the highlighted areas.
Set double-spacing on a new Word document by right-clicking the blank page and repeating the "Paragraph", "Line Spacing" and "Double" process. As soon as you start typing, your lines will show as double-spaced.
