Double-space your short story. Most literary publications like submissions to be double-spaced. If you've written your story in single-space, highlight the text and change it to double-space.
Include a header that says the title of your short story, your name and your contact information, including phone number and email address. Make sure this is on every page.
Include a footer that has page numbers for every page of your short story.
Include a cover page with your contact information and a brief note to the editor, detailing previous publications, awards and other information relevant to your career as a writer. Avoid giving a summary of the story or sharing why you wrote it. Stick to the facts of your career.
Print your short story on just one side of the page.
