Mastering the Art of Book Interior Design: A Comprehensive Guide for Self-Publishers

As a self-publisher, your primary focus may be on writing a captivating story or sharing valuable information, but the presentation of your book's interior is equally crucial in providing a seamless, enjoyable reading experience. While a well-designed cover may attract potential readers, the interior layout and design are what keep them engaged until the very last page. From typography and margins to headers and footers, there are numerous aspects to consider when creating a professional-quality book. In our comprehensive guide, we will cover the essentials of book interior design, providing self-publishers with valuable insights and practical tips to ensure a polished and engaging finished product.

The process of designing a book's interior comprises several key elements, each of which contributes to the overall readability, aesthetics, and professionalism of the final product. Among them, typography selection and formatting are paramount, as the choice of font, size, and style has a significant bearing on not just readability but also the tone and atmosphere of your book. Beyond typography, meticulous attention to page layout is essential to create a balanced, visually appealing design that effectively guides readers through your content.

Page margins, an often overlooked aspect of book design, play a vital role in the visual balance and overall presentation of your book's interior. Properly adjusted margins ensure adequate space for binding while leaving ample room for readers to comfortably hold and turn pages without disrupting the text. In addition to margins, headers and footers warrant careful consideration, as they often house critical information such as chapter titles, page numbers, or author name and serve as visual anchors and navigational tools for the reader.


Typography Matters: Fonts, Sizes, and Styles

Typography is an essential component of book interior design. Fonts, sizes and styles play a vital role in creating an easy-to-read, visually appealing book that keeps readers engaged. Consider the following factors when choosing and formatting your book's typography:

  • Font Selection: Choose a legible and attractive font that reflects the tone and genre of your book. Serif fonts are widely used for body text due to their readability, while sans-serif fonts are preferable for headings and subheadings. Avoid using overly decorative or stylised fonts.

  • Font Size: Opt for a suitable font size to maintain easy readability without making the text appear cramped or unnecessarily large. Many novels and non-fiction books use a font size between 10-12 points, depending on the typeface and desired appearance.

  • Font Styles: Utilise bold, italic, and underlined text judiciously to emphasise specific words or phrases without overdoing it. Overuse of these styles can lead to visual clutter and disrupt the reading experience.


Perfecting Page Layout: Margins, Columns, and Gutter Widths

A well-designed page layout is essential for a visually balanced book interior. Pay close attention to margins, columns, and gutter widths to create a professional and comfortable reading experience:

  • Page Margins: Establish proper margins to ensure adequate space for binding and to create ample room for holding and turning pages. Standard margins typically measure 2-2.5 cm on the top and bottom, while inner margins (or gutters) may be slightly wider to accommodate binding.

  • Columns: For most books, a single column per page is suitable. However, specific genres, such as educational resources or textbooks, may benefit from a multi-column layout to organise content more effectively.

  • Gutter Widths: When designing a book with facing pages, ensure an adequate gutter width (the space between the text on both pages) to prevent text from disappearing into the binding or appearing cramped. This width will vary depending on factors such as page size and binding type.


Headers and Footers: Guiding the Reader Through Your Book

Headers and footers act as visual anchors for readers, providing essential navigational information and adding a polished touch to your book's design:

  • Headers: Place chapter titles, section headings, or author name in the header area but ensure that they do not interfere with the main text on the page. Use a consistent style and font throughout the book for a cohesive and professional appearance.

  • Footers: Include page numbers in the footer area, typically centred or aligned to the outer margin. Match the font and style used in the header to maintain continuity throughout your book.

Choosing the Correct Format: From Hardback to A5 Size

The choice of book format impacts the interior layout, design, and printing options. Consider these factors when selecting a format for your book:

  • Hardback or Paperback: Hardback books offer a more durable, prestigious option, while paperbacks are more cost-effective and lightweight. Your choice will depend on your target audience, budget, and personal preferences.

  • A4 or A5 Size: A4 size is suitable for textbooks, educational resources, and illustrated books, while A5 size is commonly used for novels and non-fiction titles. Consider the overall presentation, distribution, and storage implications when choosing the appropriate size.

Paper and Print Options: Navigating GSM and Colour Choices

The specific paper and print options you select can impact the aesthetics and overall feel of your book:

  • Paper Selection: 100gsm uncoated paper offers a more tactile, matte finish, while 150gsm silk paper provides a smoother, glossy feel. Your choice will depend on factors such as book genre, personal preference, and desired appearance.

  • Print Options: Black and white printing is cost-effective and suitable for most novels and non-fiction titles. In contrast, colour printing may be necessary for illustrated books, children's titles, or textbooks, providing a more vibrant and engaging reading experience.


Designing the interior of a book is as much an art as writing its content. By mastering typography, page layout, headers and footers, and format selection, you can create an engaging and professional book that captures the reader's attention and delivers an enjoyable reading experience.
