Novel Formatting Guidelines

Novel formatting guidelines help ensure your manuscript looks professional and is easy to read for editors, agents, and publishers. Formatting a novel has its own set of rules. Here’s a checklist to follow for professional novel formatting:

  • Font size should be 12-point
  • Avoid decorative fonts; keep it simple and clean

  • Use bold or all caps if desired, but stay consistent
  1. Headers and Footers
  • Include a header with your last name, book title (shortened), and page number
  • Example: Smith / Lost Shadows / Page 34

  • Centered on the page:

    • Book title in bold or caps
    • Your name (or pen name) below the title
    • Contact info (name, address, phone, email) in top-left if submitting to agents

Frequently Asked Questions

How to format a book for publishing

When you're getting your book ready for publishing, the very first thing to focus on is creating a layout that's clean and easy for readers to navigate. Think about choosing a standard, widely recognized font like Times New Roman, and ensure the text size is a comfortable 12 points. To improve readability and prevent eye strain, it's generally recommended to double-space your entire manuscript. Pay close attention to your page margins as well; aiming for a uniform one-inch margin on all four sides provides a balanced and professional look. Finally, and crucially, always save your completed manuscript in the specific file format requested by your publisher. More often than not, this will be either a Microsoft Word document (.doc or .docx) or a portable document format (.pdf). These foundational elements contribute significantly to the overall reading experience and demonstrate attention to detail in your presentation.

What is the correct format for a book?

The correct format depends on whether you’re self-publishing or submitting to a traditional publisher. As a general rule of thumb, for novels, it's standard practice to use a font size of 12 and ensure your text has double spacing. Maintain 1-inch margins on all sides of the page, and when starting a new paragraph, use an indent instead of leaving a blank line between paragraphs. Don't forget to include page numbers throughout your manuscript. Furthermore, your title page should clearly display your name alongside the title of your book. To maintain consistency and make it easier for anyone reviewing your work, it's also advisable to include a header on every page that features your last name and the title of your book.

How many pages is a novel?

A typical novel is usually 200 to 400 pages long, but it can vary a lot. Some short novels (novellas) are around 100–150 pages, while epic stories can be 500 pages or more. It really depends on the genre, story complexity, and target audience. Word count is a better guide—80,000 to 100,000 words is standard for most novels.

What is the first step to publishing a book?

The first step to publishing a book is to finish writing your manuscript and revise it carefully. Once you feel confident, decide whether you want to self-publish or go through a traditional publisher. If you choose traditional, you’ll need to prepare a query letter and synopsis, and start looking for agents or publishers that accept submissions in your genre.
