Book Design & Layout: How Great Design Turns a Manuscript into a Real Book

You’ve poured your heart into writing your manuscript. Now comes the part that many authors underestimate: book design and layout. This is where your words are transformed into a professional, readable, and beautiful book that readers actually want to pick up, buy, and recommend.

In this guide, we’ll walk through the essentials of book design and layout, why they matter, and what to consider before you go to print.

What Is Book Design?

Book design is the process of planning the visual and structural elements of your book, including:

  • Trim size (the physical size of your book)

  • Margins and gutters

  • Fonts and typography

  • Chapter openings and headings

  • Page numbers and running headers/footers

  • Front matter (title page, copyright, dedication, contents)

  • Back matter (acknowledgements, index, author bio, references)

  • Cover design (front, back, and spine)

Good book design makes your book:

  • Easy to read

  • Visually appealing

  • Professionally finished (so it can sit confidently on any bookstore shelf)

Why Book Layout Matters So Much

Book layout is the detailed arrangement of text and images on each page. It’s the difference between a book that feels “homemade” and one that feels “bookstore quality”.

A strong layout will:

  • Improve readability and flow

  • Prevent awkward line breaks, widows, and orphans

  • Ensure consistent spacing, fonts, and styling

  • Make your book printer-friendly, reducing costly reprints and errors

If you’ve ever opened a book and immediately felt it was “hard to read”, that was a layout problem.

Key Elements of Professional Book Layout

Let’s break down the main components you (or your designer) should focus on.

1. Choosing the Right Trim Size

Common trim sizes include:

  • 5” x 8” or 5.5” x 8.5” – popular for novels and memoirs

  • 6” x 9” – often used for non-fiction, self-help, and business books

  • UK/AU sizes (e.g. 198 x 129 mm, 234 x 156 mm) – common in local trade publishing

  • Larger formats (e.g. 210 x 297 mm A4) – ideal for workbooks, manuals, and textbooks

Your trim size affects:

  • Page count

  • Printing cost

  • How your book feels in the hand

  • How much text fits comfortably on a page

It’s worth choosing a size that matches reader expectations for your genre.

2. Typography: Fonts, Size & Line Spacing

Typography is where design meets readability.

Interior font tips:

  • Use a serif font for body text in most print books (e.g. Garamond, Minion, Caslon, Baskerville). Serif fonts guide the eye along lines of text.

  • Use a sans serif font for headings, subheadings or captions if you want a more modern look.

  • Typical body text size for print is between 10 pt and 12 pt, depending on the font.

  • Line spacing (leading) is usually set around 120–140% of the font size for comfortable reading.

Avoid:

  • Too many different fonts – 2 or 3 is usually enough.

  • Tiny type to reduce page count – it might save a few pages, but it will cost you readers.

3. Margins, Gutters & White Space

Margins and white space give your text room to breathe.

  • Outer margins should be wide enough that thumbs don’t cover the text when the book is held.

  • Inner margins (the gutter) must allow for the spine, so text doesn’t disappear into the fold.

  • Use consistent margins throughout the book for a polished, professional look.

White space is not “wasted space” – it’s what makes your pages feel open, inviting, and easy on the eyes.

4. Hierarchy: Headings, Subheadings & Body Text

A clear hierarchy helps readers navigate your book.

Make sure:

  • Chapter titles stand out clearly (larger size, different font, or styling).

  • Subheadings are visually distinct from body text but still consistent throughout the book.

  • Bullet lists, quotes, and call-outs have their own styling, so they’re easy to recognise.

Consistency is key. Once you choose a style for a particular element, stick with it.

5. Front Matter & Back Matter

Your book is more than just chapters.

Common front matter elements:

  • Half-title page

  • Title page

  • Copyright page

  • Dedication

  • Table of contents

  • Foreword / Preface / Introduction

Common back matter elements:

  • Acknowledgements

  • Notes or references

  • Glossary or index

  • About the author

  • Call to action (e.g. visit your website, join your newsletter, follow on social media)

Thoughtful front and back matter reinforces your professionalism and can help with marketing and future sales.

Cover Design: Your Most Important Marketing Tool

People really do judge a book by its cover.

A strong cover design should:

  • Clearly communicate the genre and tone of your book

  • Be easy to read in both print and thumbnail form online

  • Include a clear title and your author name

  • Use imagery or typography that fits your audience and subject matter

  • Allow for spine text (if your page count is high enough) and a properly designed back cover with blurb, barcode, and publisher/author info

Your cover is often the first – and maybe only – chance you get to make a reader curious enough to pick up your book.

Layout for Different Types of Books

Different book types have different layout needs.

Fiction & Memoir

  • Focus on flowing, comfortable body text.

  • Simple chapter headings, minimal distractions.

  • Occasional scene breaks styled consistently (e.g. extra space or a small ornament).

Non-Fiction & Business Books

  • Use clear headings, subheadings, bullet lists, and call-outs.

  • Consider diagrams, charts, and pull quotes to break up text.

  • Use consistent styling for tips, case studies, and examples.

Illustrated Books, Workbooks & Children’s Books

  • Layout needs to support images, sidebars, and activities.

  • Text may wrap around images or sit in defined blocks.

  • Colour choices and type must work well with the illustrations and intended age group.

Common Book Layout Mistakes to Avoid

Here are some issues that instantly make a book look amateur:

  • Using default Word settings without proper typesetting

  • Too many fonts or inconsistent styling

  • Uneven spacing between paragraphs or around images

  • Widows and orphans (single words or lines left stranded at the top or bottom of a page)

  • Inconsistent chapter headings or page numbering

  • Low-resolution images that print blurry or pixelated

  • Incorrect margins that cause text to disappear into the spine

A professional book designer or typesetter knows how to solve all of these before your files go to print.

Working with a Professional Book Designer

While DIY layout tools exist, there are real benefits to working with a specialist in book design and layout, especially if:

  • This is your first book

  • You’re aiming to sell through bookstores or online retailers

  • Your book contains lots of images, charts, or complex formatting

A professional designer will:

  • Recommend the best trim size, fonts, and layout for your genre

  • Prepare print-ready files that meet your printer’s specifications

  • Help you avoid costly errors or multiple rounds of reprints

  • Give your book a polished, bookstore-quality finish

Think of it as an investment in your reputation as an author and the long-term success of your book.

Preparing Your Manuscript for Layout

You’ll get the best results (and often save money) if you prepare your manuscript properly before it goes to design.

  • Finalise your text – proofread and edit before layout begins.

  • Use simple Word styling (Headings, Normal, etc.), not manual formatting everywhere.

  • Clearly mark elements like quotes, sidebars, or call-outs.

  • Supply high-resolution images (usually 300 dpi at print size).

  • Confirm whether you’ll be doing print, ebook, or both, as formats have different requirements.
