Open the word processing program you are using to write the novel.
Click on the tab in the menu bar that allows you to access the document formatting. The name of this tab will vary in different word processing programs. Some common names for it will be, "Format," "Document," or "Text."
Move the mouse to a heading that says "Margins," or something similar to it. There should be boxes that allow you to adjust the margins of the document. Set the Top/Bottom/Left/Right margins to 1-inch all the way around. The left margin should be justified. The right margin must remain ragged.
Click on the tab in the menu bar that allows you access to the "Font." This may be a tab, or a subheading under another tab.
Select a font and type size. The size should usually be set to 12. Courier and Courier New are the most traditional fonts. However, Times New Roman also is fairly accepted.
