Good Book Cover Design: Judging a Book by its Cover
Whether we apply it to books themselves or to judging attitudes in general, we are all familiar with the old maxim “don’t judge a book by its cover.” Although we hope to not judge others by their appearances, to some extent we judge books themselves by their covers. Else, why would graphic designers spend so much time and effort creating eye-catching book covers?
Figure 1: With so many books to choose from, cover designs serve an important function in distinguishing between genres [1].
Material Considerations
Graphic design aside, the material of a book cover is an important consideration when tailoring to a specific audience. Generally, hardcovers are preferred by most readers, especially if they are looking for a long-term addition to their personal library or intend to carry a physical copy around. A paper-over-board cover particularly applies to textbooks (to be carried around by students) or to children’s books while fiction hardcover designs are usually printed onto a dust jacket—a protective paper sleeve—and feature inside flaps where a synopsis and author bios are printed [2].
Of course, many hardcover books are also sold with softcover variants that make them more affordable. Ebooks and audiobooks are likewise preferred for advantages in both affordability and portability. Covers for digital formats vary between screen sizes and software, so often a thumbnail will perform the same function as a full-sized dust jacket although these smaller mediums necessitate simpler visuals and clearer fonts [3]. Regardless of format, book covers remain essential to their marketing whether on the shelf or online. What makes a good book cover, therefore, is not so much artistic value as whether or not it stands out in the market.

Design that Matches Genre
Most readers start their search for literature with a specific goal in mind. An avid reader of fantasy, for example, is not likely to pick up a textbook on fluid mechanics and decide to read that for fun instead. Therefore, each genre—or subgenre—caters its book covers to customer preferences and the standards set by previous publications. Often, readers can identify whether a book falls into the category they are looking for based solely on the cover art and fonts. This concept can be referred to as “cohesion” and is not often overlooked, making the artistic divide between genres helpful for readers with particular tastes [5]. The idea of consistency is not unique to marketing for books, but is an essential element in television and consumer products. By maintaining cohesive design, designers in both advertising and engineering successfully earn consumers’ trust and improve sales by taking advantage of familiarity.
Fiction works generally convey a broad set of emotions and messages, and a good book cover should reflect its central themes. For example, many readers of epic fantasy are attracted to the genre by interesting worldbuilding combined with an engaging struggle between ultimate good and evil. That said, good covers in this genre include illustrations of a scene, setting, or character from the novel that allude to the main conflict and make their world unique [6]. Especially in adult fantasy, darker, earthy colors along with typography and older fonts contribute to a sense that the book has a setting and plot not meant to be taken lightly [7]. Fantasy that draws heavily from fairy-tales or is targeted to younger audiences generally benefits from brighter colors and playful but easy-to-read fonts. Good book covers in fantasy give a preview of the plot that makes the potential reader consider if it is the kind of story they will enjoy. However, covers that try to represent every aspect of the book are often too busy and serve as a reminder that sometimes less is more.

Regency era works and romances often employ flowing, decorative fonts to depict a sense of beauty and delicacy to the story. However, fonts that are too difficult to read—such as flourished cursive fonts—could turn some readers away. These decorative scripts can also appeal more to older target audiences so youth fiction will generally avoid more complicated art and typography. Additionally, too many different fonts on the same cover can turn readers away as it can make the design look too busy and disorganized [9]. Complex fonts and images likewise hint toward a correspondingly complex plot with sudden twists and changing perspectives.
While being consistent within the genre is important, successful book covers—the ones that draw a reader’s attention—feature some element that strays from the norm. Using contrasting colors for a genre whose covers normally feature one palette will at least spark curiosity in a reader, and even picking up the book increases the chances of a sale. Noticing a cover is just the first step, however, and skeptical readers think more about the summary and reviews printed on the back or in one of the dust jacket flaps. The author normally has little control over the summary itself, which is often placed in the hands of publishing companies and literary agents, but good synopses are not afraid to share what makes a story unique, even if it gives some spoilers [10]. By hinting at twists, character reveals, and major plot points, summaries help advertise why a novel brings something unique to the world of literature and can inspire a reader to start chapter one. Like most consumer products, book covers need to sell themselves, and the best ones not only show but tell why someone needs to read it.

Nonfiction books, especially textbooks, tend to rely less on flashy imagery for their covers and instead opt for a more serious tone that contributes to credibility. Textbooks, for example, do not generally require an eye-catching image for the reader and if they do, they use only one main symbol and leave the text to say the rest [5]. Reference books rely mostly on the content and the credentials of the authors to convince the reader that the information they are seeking is included in the text and valid.
Conclusion
In a world saturated with diverse literature and equally diverse preferences, good marketing is a requirement for many new additions, especially those without a good name to go with them to start. Professionally designed covers have been shown to increase a book’s visibility on social media and make readers more likely to pick it up, read it, and eventually buy it [12]. Don’t feel bad the next time you toss aside a perspective read after glancing at the cover and its inside flaps because, in a way, books were designed to be judged by their covers. Why else would they have them?
