Line spacing in Word 2010 can help improve readability. In Word paragraph spacing can make documents look cleaner too.
Just as you can format spacing between lines in your document, you can choose spacing options between each paragraph. Typically, extra spaces are added between paragraphs, headings, or subheadings. Extra spacing between paragraphs can make a document easier to read.
You can use Word's convenient Set as Default feature to save all of the formatting changes you've made and automatically apply them to new documents. To learn how to do this, read our article on Changing Your Default Settings in Word.
