A good book cover design brief includes two layers of information: technical specs your designer needs to build the file correctly (trim size, page count, printing platform) and creative context that shapes the visual direction (genre, target reader, comparable covers, and enough story detail to capture the right mood without overwhelming the designer with plot). Most authors overload one layer and starve the other; getting both right is what separates a smooth commission from a frustrating cycle of revisions.

What Is a Book Cover Design Brief and Why Does It Matter?
A design brief is a structured document that communicates everything your cover designer needs to produce a cover that fits your genre, appeals to your target readers, and meets the technical requirements of your printing platform. Without one, both sides are guessing.
The Alliance of Independent Authors (ALLi) advises that getting the brief right from the start avoids misunderstandings that cost time, money, and energy on both sides. At ebookpbook, we see this pattern repeatedly: authors who arrive with a well-assembled brief typically approve their cover in one or two revision rounds, while authors who skip the brief often need four or five. Every element in the brief feeds into one core question: what should a reader instantly understand and feel when they see this cover as a thumbnail on Amazon or in a bookshop?
What Technical Specs Should You Include in Your Cover Brief?
Technical specifications are the foundation of any cover file. Missing or incorrect specs lead to rejected uploads, reprints, and wasted designer time. Include these details at the top of your brief so the designer can set up their template correctly.
Core specs every brief needs
Your designer needs to know the trim size (the finished dimensions of your printed book, such as 5.5×8.5 or 6×9 inches), the total page count (or your best estimate, since this determines spine width), and which printing platform you are using. Platform matters because bleed requirements and template formats differ. KDP requires paperback covers as a single PDF with 0.125-inch bleed at 300 DPI in CMYK; hardcovers need a larger 0.625-inch bleed. IngramSpark has similar specs but mandates barcodes on all covers. Draft2Digital recommends a 1600×2400 JPEG for ebook covers and handles resizing for various storefronts.
Both KDP (via the KDP Cover Calculator) and IngramSpark provide tools to generate downloadable cover templates based on the technical specifications of your book. Share the template file with your designer; it eliminates guesswork about spine width, barcode zones, and safe areas. If you are publishing on multiple platforms, mention all of them upfront so the designer can build files that work everywhere.
Paper type and binding
Spine width depends on page count and paper stock. KDP’s white paper produces a thinner spine than cream paper for the same page count, and IngramSpark’s groundwood stock differs again. Tell your designer whether you are using white or cream paper, whether the book is a paperback or hardback, and whether you want a matte or gloss cover finish (matte tends to mute colour, which may affect the designer’s palette choices).
Spine text
KDP requires a minimum of 79 pages before spine text is permitted. If your book is close to that threshold, tell your designer so they can plan accordingly. IngramSpark has its own spine safety guidelines; for spines 0.35 inches and wider, text must sit at least 0.0625 inches from the left and right edges.
Ebook cover specs
If you also need an ebook cover, include that in the brief. KDP recommends 2560×1600 pixels at 300 DPI in JPEG format. IngramSpark’s ebook spec is a standalone JPG, minimum 1,600 pixels on the shortest side. Critically, ebook covers must be in RGB colour, not CMYK, since they display on screens. A single file cannot serve both print and ebook purposes well.
File deliverables to request
Specify what files you expect back: a print-ready PDF, an ebook-cover JPEG or PNG, and the original layered source file (.psd for Photoshop or .ai for Illustrator). That layered file is your insurance policy; if you ever need to update the spine width or change a subtitle, it makes that possible without starting from scratch. Many authors forget to request it. Ask for it upfront.
How Much Creative Detail Should You Give Your Cover Designer?
This is where most briefs either starve the designer or drown them. The goal is to give enough context for strong visual decisions without requiring the designer to read your manuscript.
Your designer will not read your book
Unless you are paying for a bespoke illustration, your designer will not read your manuscript. What they need is a 1-2 paragraph synopsis (spoiler-light is fine), the genre and subgenre (be specific: “cozy mystery” is far more useful than “fiction”), 3-5 keywords that capture the mood (dark, whimsical, tense, warm, literary), and the setting or time period if it is visually relevant. A cover is not an illustrated plot summary; it is a mood signal that tells the right readers “this book is for you” in under two seconds at thumbnail size.
What creative information actually helps
Designers consistently say the most useful creative information is: your target reader described as a specific person (not a demographic range), the emotion you want the cover to trigger, and examples of covers you admire with an explanation of why. “I like Cover X because of the muted colour palette and the way the title dominates the image” gives a designer something to work with. “I like Cover X” alone does not.
If your book features characters on the cover (common in romance, fantasy, and thriller), provide clear physical descriptions of only those who will appear. Skip secondary characters, plot details, and backstory. If your book has a strong visual motif (a lighthouse, a red door, a distinctive weapon), mention it as a suggestion rather than a requirement.
What creative information gets in the way
Full plot summaries, scene-by-scene descriptions, and exhaustive character bios overwhelm a designer and paradoxically produce worse covers. When a designer has too many elements to consider, they hedge by cramming visual references onto the cover, and overloaded covers fail at thumbnail size.
Equally, avoid vague instructions like “make it pop,” “be creative,” or “I’ll know it when I see it.” These phrases force the designer to guess, which leads to more revision rounds and higher costs. If you genuinely have no visual preference, say so honestly and let the designer lead; that is a clearer instruction than vague enthusiasm.
How Do You Find and Present Comp Titles for Your Cover Brief?
Comp titles (comparable titles) are one of the most valuable things you can include. They show your designer what the market expects and what readers in your genre respond to visually.
How to find good comps
Open Amazon and browse the top 20 bestsellers in your specific subcategory (not a broad parent like “Fiction”). Look at which covers share visual patterns: similar typography, colour palettes, imagery types, and composition. These patterns are genre signals that readers use to identify books they might enjoy. Your cover needs to fit within those signals while still being distinctive.
Aim for 3-6 comp covers published within the last two to five years. Avoid universal bestsellers like Harry Potter; they are too broad to be useful reference points. Look for books that have found an audience in your specific subcategory.
How to present comps effectively
For each comp, include a link to the book’s Amazon page and a short note explaining what you like about it. Be specific: “I like the hand-lettered title treatment and the cool blue-green palette” is useful. “I like this one” is not. Also note anything you dislike: “I like the composition of Cover Y but the pink colour scheme is wrong for my book’s tone.” This gives the designer a visual vocabulary rather than forcing them to interpret abstract descriptions.
Comps guide direction, not duplication
An important distinction: comp titles show your designer the visual neighbourhood your cover should live in, not a request to copy. Asking a designer to replicate a specific cover is ethically problematic and potentially infringing. Use comps to communicate the genre signal, not the exact execution.
Does a Fiction Brief Differ from a Nonfiction Brief?
Yes. While both need technical specs and comp titles, the creative emphasis shifts significantly.
Fiction briefs: mood and genre first
For fiction, the brief leans heavily on genre conventions, mood, and emotional tone. Romance readers expect specific visual cues (couples, warm palettes, script fonts). Thriller readers expect dark tones, bold sans-serif type, and isolated figures. Fantasy readers expect ornate typography, rich colour, and hints of scale. Your brief should spell out the subgenre precisely; “romantic suspense with small-town setting” gives the designer far more to work with than “fiction.” At ebookpbook, the pattern is consistent: fiction covers where the designer understood the subgenre land well on the first draft, while covers briefed as just “fiction” almost always need direction-correcting revisions.
Nonfiction briefs: authority and clarity first
Nonfiction covers need to communicate what the reader will learn or gain. Typography plays a more central role; for many business and self-help titles, the type treatment is the entire cover. The title and subtitle carry the selling load, so they need to be clear and hierarchy-correct at thumbnail size.
Nonfiction briefs benefit from more text-heavy planning: include the exact title, subtitle, any endorsement or foreword credit, and all back cover copy (testimonials, bullet-point takeaways) so the designer can plan the layout from the start. White space matters more in nonfiction design; clean layouts with a single strong image outperform cluttered designs with multiple visual elements competing for attention.
What Are the Most Common Design Brief Mistakes?
Designers are consistent about what goes wrong. These mistakes come up repeatedly in designer forums, blog posts, and intake-form guidance.
Being vague where specificity matters
“Make it look professional” and “I want something eye-catching” tell the designer nothing actionable. Instead, describe the specific genre signal: “I want a reader browsing Amazon’s cozy mystery section to immediately recognise this as a cozy; warm palette, illustrated style, readable title at thumbnail size.”
Micromanaging the design
Dictating exact fonts, precise colour hex codes, and detailed compositions defeats the purpose of hiring a designer. Describe the outcome you want (“my cover should feel moody and atmospheric, like it belongs next to Comp X and Comp Y”), not the execution (“use Garamond 24pt in #2C3E50”). The exception is series branding, where specific fonts and layout grids must remain consistent across volumes.
Forgetting technical specs until the end
A designer who builds an ebook-only cover and then discovers you also need a print wraparound with a spine has to rework the entire layout. Include all formats and platforms from the start; a cover built only to KDP’s template may not fit IngramSpark’s barcode placement or spine safety requirements.
Providing poor-quality reference images
If you are supplying photographs (an author headshot, a landscape image, a logo), send the highest resolution available. Print covers need 300 DPI at the final output size; a photograph that looks sharp on screen at 72 DPI will print poorly.
Not providing the final text
The designer needs the exact title, subtitle, and author name before they begin, because the length of those strings directly affects the layout. A title change after the design is complete can force a full redesign of the type treatment. Include your final back cover blurb before the designer starts the full wraparound; placeholder text leads to awkward spacing when the real text is swapped in.
Soliciting feedback from the wrong people
Friends and family are not your target audience. If you want external feedback on cover drafts, show them to readers of your genre or run an A/B test using Facebook or Amazon ads. A cover that your partner loves but your target market ignores is a failed cover.
Frequently Asked Questions
How much does a custom book cover design cost?
Premade covers (pre-designed templates customised with your title and name) typically cost $50 to $200. Mid-range custom covers using photo manipulation and professional typography run $300 to $800. Premium covers with original illustration or complex art direction cost $1,000 and up. Genre affects pricing: fantasy and sci-fi covers tend to cost more due to complex imagery, while nonfiction typography-led covers tend to cost less. Budget also increases if you need multiple formats (ebook, paperback, hardcover) or tight turnaround times.
Should I give my cover designer the full manuscript?
No. Designers work from a concise brief, not a full manuscript. Provide a 1-2 paragraph synopsis, the genre and subgenre, the mood and tone, and descriptions of any characters who will appear on the cover. The designer needs visual ingredients, not the full story. Sending a 90,000-word manuscript signals that you have not distilled what the cover needs to communicate, and most designers will not read it.
What if I have no visual ideas at all?
That is perfectly fine. Many experienced designers prefer working from a brief that describes the target reader, the genre, and the comparable titles rather than one that dictates specific visual elements. If you have no strong visual preferences, say so and let the designer lead the creative direction. Your job in this case is to provide the market context (genre, audience, comps) and evaluate the drafts against whether they hit the right genre signal, not whether they match an image you had in your head.
How many revision rounds should I expect?
Most mid-range designers include two to three rounds of revisions in their fee. A good brief reduces the need for major revisions; with a clear brief, you might only need minor tweaks (font size adjustment, colour shift, text repositioning). If you find yourself requesting fundamental direction changes in round three, the issue is usually the brief rather than the designer. Additional revision rounds beyond what is included in the contract typically incur extra charges.
Do I need separate files for KDP and IngramSpark?
Usually, yes. While both platforms require a single PDF wraparound cover, their barcode placement, spine safety zones, and template dimensions differ slightly for the same trim size and page count. KDP places a system-generated barcode in a 2-inch by 1.2-inch zone in the lower left of the back cover, while IngramSpark requires you to supply the barcode yourself. Ask your designer to produce platform-specific files from the start rather than trying to make one file work for both.
