Line spacing is the amount of space between lines within a paragraph. By default, Word starts each new document with single spacing, which provides just enough space between lines so that letters don't overlap. You might want to switch to double-spacing for rough drafts of documents so that you have extra room to write in edits by hand. Or try one-and-a-half spacing, which makes text easier to read by separating lines with an extra half-line of blank space. You can also control the amount of space between paragraphs. For example, documents with an extra half-line of space between paragraphs are easier to read, and you won't have to press Enter twice to end a paragraph and insert an extra blank line between paragraphs.
Change Paragraph Spacing
To change the spacing between paragraphs for the selected text, designate a new setting in the Before and After boxes under Spacing. Use the spin arrows to set paragraph spacing in points, or type in a value. The Before box sets spacing at the top of the paragraph; the After box sets spacing at the bottom of the paragraph. Click OK to close the dialog box.
