The "single" line spacing value is 1.15, or 115 percent. The page describes how to change the default setting. The single line in Word is analogous to using "auto" leading in Adobe products, or 100% in CSS, and so on.
The gap between each line in a paragraph is referred to as line spacing. You may set the line spacing in Microsoft Word to be single-spaced (one line high), double-spaced (two lines high), or any other quantity you wish. Word 2013's default spacing is 1.08 lines, which is somewhat more than single-spaced.
Word's default line spacing is 1.15. Paragraphs are followed by a blank line by default, and headings have a space above them. , and then select Line Spacing Options. If you wish to adjust the spacing between paragraphs, change the Before and After options. For example, if you want to make sure that there is no space before or after a section heading, set the value in the Before and After boxes to 0.
Change the line spacing throughout a document.
The spacing of all the lines in a paragraph is controlled by line spacing. Assume you're using a 12 point font for your paragraph's text. The distance between lines will be 12 points if you pick single line spacing. The distance between lines will be 24 points if you pick double spacing. These are called default settings.
There are three other options available: left margin, right margin, and both margins. With these options, you can control the space on each side of the paragraph (and to an extent, the top and bottom of the paragraph as well).
For example, if you want half as much space on each side of the paragraph as there is between lines of type, you could set the left and right margins to 6 points. This would make the whole paragraph level with the baseline of the second line of text.
Alternatively, if you wanted one-third the space on each side, you could set the left and right margins to 3 points. This would mean that the first line of text would be aligned with the baselines of the other two lines.
Finally, if you want the full width of the paragraph area without any space on either side, then use 0 points for the left and right margins. This would cause the first line of text to be flush with the last line of text rather than being indented.
"Double-spaced" simply indicates that each line of type is separated by one blank line. A double-space mode is available in all current word-processing systems. Line spacing should be set to "Double" in Microsoft Word 2013, and no additional spaces should be inserted before or after paragraphs.
In many writing, especially legal writing, double-spacing—24 points per line or 3 lines per inch—became the norm. On a regular letter-sized page, a one-inch top margin and a half-inch bottom margin are left, resulting in 9.5 inches of useable area. A quarter sheet of paper is 18 inches by 24 inches, so it can hold 12 single-spaced pages.
One point used to be equal to 1/72 of an inch; now it's equal to 2.54 centimeters. So, double spacing means the text is written over two columns, with each column taking up 17.6 percent of the total page width.
This amount of space allows for enough room to write out full sentences without running out of room. It's considered good practice in journalism and other creative fields to provide this much white space around words and phrases to allow for its proper placement in the layout.
The default setting for most word processors is now single spacing, which gives you only one column per page. To create two columns on a page, you have two options: You can manually divide your document into two columns (using the Page Layout tab), or you can use the Indent option from the Home tab to start every new paragraph at a horizontal indent from the left edge of the page.
Your line-spacing will be set to single-spaced by default, however most legal documents are double-spaced. Double-spacing allows the reader to scribble notes between lines, but it takes twice as much paper or twice as long to scroll through on the screen. It also makes skimming the document harder. For these reasons, most documents are written with a space after each line of text: this is called "manuscript" style.
When you print out a document, your printer will usually offer to print it in both single and double-spaced formats. Selecting double spacing uses more ink and paper, so use this option if you plan to print many copies. If you just need to write something down quickly, you can always handwrite a note at the end of each line.
Manuscript style is used mostly for original documents that you want to look nice when they're not being read by others. This includes letters, reports, and essays. Some examples of double-spaced text include The Elements of Style, Whitman's Poetry, and Gertrude Stein's prose. Text in manuscript style is often followed by a half-line space and an indentation of 1/4 inch or 1/2 inch.
Paragraphs should be indented 1/2 inch or even 1 inch from the top and bottom of the page.
