Your book cover has about two seconds to grab a browsing reader. On Amazon, in a social feed, on a bookstore shelf, it doesn't matter where. In that blink, they decide whether to click, pick up, or scroll past.

No amount of brilliant writing fixes a cover that whispers "amateur."

This is exactly the process our team walks authors through at Northern Star Press, and most self-published authors know it already. And yet, when it's time to actually design a book cover, they freeze. They worry about cost. They doubt their own eye. They're scared of picking imagery that quietly signals the wrong genre and sends the right readers scrolling straight past.

This guide is built for exactly that moment.

It assumes you've never opened a design tool in your life. We'll walk through understanding your genre's visual language, choosing a tool that fits your budget and skill level, working through the actual design process, and exporting a print-ready file that meets KDP's specs without a single rejection email. You'll learn which free and low-cost tools genuinely hold up, how to test a cover before you commit to it, and how to dodge the mistakes that make a cover scream "self-published" for all the wrong reasons.

By the end, you'll have a clear plan and a checklist you can work through from blank canvas to a cover that belongs on the same shelf as a traditionally published title, without spending a fortune to get there.

Ready to make a cover that sells your book before anyone reads the first page? Let's get into it.

Understanding Your Genre: The Non-Negotiable First Step

Before you touch a single font or image, you need to know exactly what shelf your book sits on.

A romance reader scrolling past a cover styled like a thriller won't stop. They'll assume, correctly or not, that the book isn't for them. Genre conventions are visual shorthand. They tell the right reader, at a glance, "this is your kind of story."

Expert Tip: Study the top 20 bestsellers in your specific genre and subgenre on Amazon. Note the colour palettes, font styles, and image types that keep repeating. Your cover should feel like it belongs on that shelf, not identical to everything else on it, but instantly recognisable as part of the family.

Design studios who work in this space every day back this up. Damonza and Nessgraphica have both written extensively about genre signalling being the single biggest factor in whether a cover actually works, ahead of originality, ahead of artistic flair.

Decoding Visual Cues by Genre

Most guides list genres and stop there. They don't explain why the conventions exist. Here's the visual DNA behind the major categories, and the emotional job each one is doing.

  • Romance: Warm, saturated colour, think reds, pinks, golds. A couple in an embrace, or a single figure caught mid-glance. Flowing script for the title. The image can be illustrated or photographic, but it always needs to feel emotionally charged.

  • Thriller and mystery: Dark, moody tones, black, deep blue, crimson. Bold sans-serif type. An isolated figure, a long shadow, an abstract sense of tension. High contrast does a lot of the heavy lifting here.

  • Science fiction and fantasy: Epic landscapes, symbolic objects, a sword, a planet, a lone tower. Fantasy tends to lean into ornate serif fonts and painterly textures; sci-fi favours sleek, futuristic sans-serifs with a glowing accent or two.

  • Literary fiction: Often typography-led with minimal imagery. Elegant serif fonts, generous white space, imagery that works on a metaphorical level rather than a literal one. The cover should signal depth before it signals plot.

  • Non-fiction and self-help: Clean, bold titles that make a promise. The author's name sits prominently. Simple icons or abstract graphics rather than photography. Colours skew bright and optimistic, yellow, orange, teal, to suggest transformation.

If you're still working out exactly which shelf your manuscript belongs on, it's worth reading about the different literary genres before you go any further. Getting this call right shapes every design decision that follows.

How to Research Your Genre Like a Pro

  1. Go to the Kindle Store, select your category, and sort by bestselling.

  2. Screenshot the top 20 covers. Paste them into a document or mood board tool (more on that next).

  3. Look for patterns. Illustrated or photographic? What colours dominate? Are titles centred or left-aligned? Is the author name big or small?

  4. Note the outliers, the covers that break the mould but still sell, and work out why they get away with it.

Expert Tip: Don't just copy the patterns, understand the emotion behind them. A thriller cover uses darkness to create unease. A romance cover uses warmth to promise connection. Every design choice should serve that underlying emotional goal, not just mimic the surface look.

Finding Inspiration and Building a Mood Board

Where to Look for Cover Ideas Beyond Pinterest

Inspiration is everywhere, but look in the right places, partly for quality, partly so you don't end up echoing someone else's design too closely.

  • Amazon bestseller lists: The most direct source. Filter by genre and subgenre.

  • Reedsy's book cover gallery: Hundreds of covers organised by genre with professional commentary attached.

  • Award galleries: AIGA's 50 Books | 50 Covers and the UK's own Academy of British Cover Design (ABCD) awards both showcase genuinely exceptional work, and both archive past winners online for free browsing.

  • Designer portfolios: Damonza, Nessgraphica, and MiblArt all publish their portfolios openly. Treat them as a masterclass in genre-specific design.

  • Social media: Instagram's #bookcoverdesign tag and TikTok's BookTok community both surface covers that are actively stopping the scroll right now.

How to Build a Mood Board That Actually Guides Your Design

A mood board isn't decoration. It's a decision-making tool, locking in your colour palette, typography style, and overall mood before you open a design tool, which saves you second-guessing every choice later.

  1. Collect 15 to 20 covers from your genre research and inspiration sources. Save them in one folder.

  2. Use a free tool like Canva, Milanote, or even a Google Slides deck. Arrange the images on a single canvas.

  3. Identify the common threads. Circle repeating colours, underline recurring font styles, note whether the imagery leans illustration, photography, or abstract.

  4. Pull out three to five core colours and place them as swatches on the board. This becomes your palette.

  5. Add a vibe word, one or two adjectives that capture the feeling you're after ("ominous," "whimsical," "authoritative"). Every design decision should be able to justify itself against that word.

Expert Tip: Keep your mood board visible while you design. If a font or image doesn't match the board's mood, it's probably wrong for your cover, even if you like it on its own.

Choosing the Right Design Tool: A Comparison for Every Budget and Skill Level

The tool you pick shapes your entire design experience. The goal is to match your budget, your skill level, and what you actually need to produce, ebook only, or ebook and print.

How to Decide: A Simple Decision Framework

Still not sure? Answer these three questions.

  1. Budget? Nothing to spend: Canva Free or the Reedsy Book Editor. A little to spend: Book Brush or Placeit add marketing power on top of the cover. A one-off budget: a service like GetCovers gives you a custom design without hiring a full studio.

  2. Skill level? Never designed anything: stick with Canva or Placeit. Comfortable learning new software: GIMP hands you total control, if you're willing to climb the curve.

  3. Need print? Your tool has to handle spine width, bleed, and CMYK colour properly. The Reedsy Book Editor and Canva Pro, paired with KDP's templates, are the safest bets.

Product Recommendation: For most first-time authors, Canva Pro is the sweet spot. Affordable, template-rich, and capable of producing a cover that passes the thumbnail test. If you're publishing in print, pair it with the Reedsy Book Editor for spine and bleed calculations you don't have to do by hand.

Core Design Principles: Colour, Typography, and Composition

Colour Psychology for Book Covers

Colour isn't decoration. It triggers emotion before a reader processes a single word.

  • Red: passion, danger, urgency. Common in romance and thrillers.

  • Blue: trust, calm, intelligence. Works well across non-fiction, mystery, and literary fiction.

  • Yellow and orange: optimism, energy, warmth. A natural fit for self-help, children's books, and contemporary fiction.

  • Black: sophistication, power, mystery. A staple in thrillers and upmarket literary covers.

  • White and negative space: clarity and modernity, increasingly popular across non-fiction and upmarket fiction alike.

Expert Tip: Limit your palette to two or three main colours plus a neutral, white, black, or grey. More than that and the cover starts to feel chaotic, which weakens its impact at exactly the moment it needs to be clearest.

Current trends favour high contrast and cleaner white backgrounds, largely because they hold up better at thumbnail size, where most readers actually meet your cover first.

Typography: Choosing Fonts That Speak Your Genre

Fonts carry personality. A horror novel set in a curly script font confuses readers before they've registered a single word of the blurb.

  • Serif fonts (Garamond, Baskerville): traditional, literary, historical. A natural fit for literary fiction, historical fiction, and memoir.

  • Sans-serif fonts (Helvetica, Montserrat): modern, clean, bold. Works well across thrillers, non-fiction, and self-help.

  • Script and display fonts: use sparingly, and only for the title. Romance often leans on flowing script; fantasy sometimes reaches for decorative, medieval-inspired type.

  • Avoid: Comic Sans, Papyrus, and anything so ornate it sacrifices readability for personality.

Expert Tip: Never use more than two font families on a cover. One for the title, which can afford to be a little decorative, and one for the author name and subtitle, which should stay simple and legible. Test your title at thumbnail size. If you can't read it there, change the font.

A quick font pairing cheat sheet:

  • For thrillers: a heavy sans-serif like Bebas Neue for the title, paired with something clean like Lato for the author name.

  • For romance: a flowing script for the title, paired with a simple serif for the author name.

  • For fantasy: an ornate serif for the title, paired with a plain sans-serif underneath so the author name stays legible.

  • For non-fiction: a bold sans-serif for the title, paired with the same family in a lighter weight for the subtitle.

Composition: The Rule of Thirds and Focal Point

A strong cover guides the eye to one dominant element, usually the title or a central image. The rule of thirds helps here: imagine a 3×3 grid over your cover, and place your most important element along one of those lines or at an intersection.

  • Keep it simple: one central image or concept. Clutter kills curiosity rather than building it.

  • Set a hierarchy: title first, largest element on the page, then the main image, then the author name. Subtitles and taglines sit smaller again.

  • Balance the layout: image on the left, text on the right, or vice versa. Symmetry can work, but asymmetry often feels more dynamic and alive.

Step-by-Step Design Process: From Blank Canvas to Final Cover

Step 1: Set Up Your Canvas With the Right Dimensions

Get the size wrong and everything downstream gets harder. Different platforms want different things.

  • Amazon KDP, ebook: 2,560 x 1,600 pixels is the recommended size (a 1.6:1 ratio). The minimum is 1,000 pixels on the longest side.

  • Amazon KDP, paperback: use KDP's cover template generator. Input your trim size, page count, and paper type, and it hands you a precise template with spine width and bleed built in.

  • IngramSpark, print: similar rules to KDP, but it needs its own separate template. Always download the latest version from IngramSpark's site rather than reusing an old one.

  • Ebook only, universal size: 1,600 x 2,400 pixels works safely across nearly every platform.

Expert Tip: Always design at 300 DPI for print. Ebooks only need 72 DPI, but starting at 300 gives you flexibility if you decide to go print later without redoing the whole design.

Product Recommendation: Canva Pro and the Reedsy Book Editor both offer pre-set KDP dimensions. If you're working in GIMP, you'll need to set the canvas size manually.

Step 2: Place Your Background and Main Imagery

Start with the background, a solid colour, a gradient, a texture, or a full-bleed image. Then add your hero image, a person, an object, a landscape.

  • Image quality: use high-resolution stock photos, at least 300 DPI at your print size. Pixelation reads as amateur instantly.

  • Licensing: make sure every image is licensed for commercial use. Unsplash (free), Shutterstock (paid), and Canva's built-in Pro library are all safe bets. This matters more than it sounds, using an image outside its licence terms can get your listing pulled.

  • Focal point: place the main subject off-centre so there's room for text. If the image is busy, a semi-transparent overlay behind the title can rescue readability without flattening the whole image.

Expert Tip: If you're using a stock photo, change it. Crop it, adjust the colours, add a filter, so it doesn't look like a template a hundred other authors have also used. Small tweaks make a real difference.

Professional designers rarely start from a blank page. Plenty of bestselling thrillers, for instance, began life as manipulated stock imagery, transformed enough that nobody would guess the source.

Step 3: Add Your Title and Author Name

Now the text that matters most. Apply the typography principles from earlier.

  • Title placement: usually the top third or centre, depending on the image. Make it large and bold enough to survive being shrunk down.

  • Author name: bottom or top, depending on how established you are. Debut authors: bottom is fine, just keep it readable. Established authors with an audience: the top can work well.

  • Subtitle: if you have one, keep it smaller and clearly subordinate to the title.

  • Contrast: dark text on a light background, or light text on dark. A subtle drop shadow or outer glow can help separation, but don't overdo it, it reads as a crutch fast.

Expert Tip: All caps or title case? All caps suits short, punchy titles, thrillers, most non-fiction. Title case tends to suit longer, more literary titles better. Test both before you commit.

Step 4: Refine With Details and Effects

Small touches turn a good cover into a great one.

  • Textures and overlays: a subtle paper texture, grain, or light leak adds depth without adding clutter.

  • Colour grading: adjust the overall tone to unify image and text. A warm filter, for instance, can make a romance cover feel cohesive rather than assembled.

  • Borders and frames: a thin border can add a polished, classic feel, particularly for literary fiction.

Expert Tip: Less is more. Every time you're tempted to add another element, ask whether it helps communicate the genre or hook the reader. If the honest answer is no, delete it.

Step 5: Design the Spine and Back Cover (Print Only)

This is where most DIY guides fall short. A print book needs a full wrap, front, spine, and back, not just a pretty front cover.

  • Spine: width is calculated from page count and paper type. Use KDP's template or Reedsy's automatic calculator rather than guessing. Include the title and author name, oriented so they're readable with the book sitting upright on a shelf.

  • Back cover: this is your sales page in print. Include a compelling blurb, not the full synopsis, just the hook, space for the barcode (KDP adds the ISBN automatically), and optionally an author photo, a short bio, or a review quote or two.

  • Bleed: extend background images and colours 0.125 inches beyond the trim line on every side. Skip this and you'll get white slivers after the book is cut.

If your back cover copy is carrying the weight of the sale, it's worth having a second pair of eyes on it before it goes to print. NSP's UK book proofreading services exist for exactly this kind of high-stakes, low-word-count copy, where one typo on the spine or a clumsy sentence in the blurb undoes hours of design work.

Step 6: Export the Right File Format

  • Ebook: JPEG or PNG, RGB colour mode. KDP recommends JPEG at 100% quality.

  • Print: PDF/X-1a, CMYK colour mode, fonts embedded, bleed included. Both KDP and IngramSpark accept this standard.

  • File naming: something clear, like "BookTitle_FrontCover_Final.pdf," saves you from opening the wrong version at 11pm the night before launch.

Expert Tip: Always preview your exported file at 100% zoom before uploading, checking for artefacts or blurriness. Upload a test file to KDP's previewer before you publish for real.

If spine width, safe zones, and file formats sound like more than you want to handle alongside the cover itself, NSP's book formatting services can take the whole interior and cover specification off your plate.

Testing Your Cover: The Thumbnail Test and Getting Real Feedback

The Thumbnail Test: Your First and Most Important Check

On Amazon, your cover shows up at around 100 to 150 pixels wide in search results. If the title and main image aren't clear at that size, you've already lost the sale before anyone reaches your blurb.

How to test it:

  1. Export your cover as a JPEG.

  2. Resize it to 150 pixels wide, any image editor or free online tool will do this.

  3. Look at it from a normal viewing distance. Can you read the title? Can you tell what the image is? Is the genre obvious at a glance?

  4. If not, go back and increase contrast, simplify the image, or enlarge the title.

Expert Tip: Run this test early in the process, not just at the end. It's easier to fix a problem before you've spent hours polishing details a thumbnail hides anyway.

Gathering Unbiased Feedback

Friends and family will tell you it looks great. You need strangers who actually read your genre.

  • Facebook reader groups: beta reader and critique communities, or genre-specific groups, are a good source of blunt, useful opinions.

  • Reddit: r/selfpublish, r/bookcovers, and genre-specific subs are goldmines for honest reactions.

  • Social media polls: post two versions on Instagram Stories and ask followers to vote, a lightweight form of A/B testing.

  • Paid A/B testing: for a small daily budget, run Facebook or Amazon ads with two different cover variants and see which pulls more clicks. It's the most data-driven route available to a self-published author, and it doesn't need a big spend to produce a useful signal.

Preparing Files for Print and Digital: Specs, Bleed, and Formats

Ebook Specifications for Major Platforms

  • Amazon KDP: JPEG or TIFF, 1,000 to 10,000 pixels on the longest side, RGB colour. Ideal: 2,560 x 1,600 px.

  • Apple Books, Barnes & Noble, Kobo: generally accept the same specs as KDP. A 1,600 x 2,400 px JPEG works safely everywhere.

  • Google Play Books: minimum 1,000 px on the shortest side, JPEG or PNG.

Expert Tip: Design once at the highest resolution you'll need, then export smaller versions for each platform. It saves time and keeps everything consistent.

Print is far less forgiving than digital. One mistake can get your file rejected outright.

KDP paperback:

  • File format: PDF

  • Colour: CMYK

  • Bleed: 0.125" on all sides, if your design has full-bleed images

  • Spine width: calculated automatically through KDP's cover template

  • Resolution: 300 DPI

IngramSpark:

  • Similar rules to KDP, but requires its own separate template download. IngramSpark is stricter about bleed and margins than KDP.

  • File format: PDF/X-1a or PDF/X-3

Using KDP's cover template, step by step:

  1. Go to KDP's Cover Creator or download the template generator directly.

  2. Enter your trim size (say, 6" x 9"), page count, and paper type.

  3. Download the template. It shows your exact dimensions, including spine width and bleed lines.

  4. Open it in your design tool as a guide layer, and build your cover on top, keeping important text inside the safe zone.

  5. Delete the template layer before you export.

Product Recommendation: The Reedsy Book Editor automates this whole process. Input your book's specs and it generates a print-ready PDF with correct spine and bleed built in already, which makes it the safest option if print is new territory for you.

Common File Rejection Reasons and How to Avoid Them

  • Low resolution: anything below 200 DPI gets flagged. Start at 300 DPI and you'll never hit this.

  • Missing bleed: if your background runs to the edge, include bleed, or you'll get white borders after trimming.

  • Text too close to the edge: keep all text at least 0.25" inside the trim line.

  • Wrong colour mode: print needs CMYK, not RGB. Convert before you export.

  • Fonts not embedded: check your PDF export settings to confirm fonts are embedded, not just referenced.

Expert Tip: Always order a physical proof copy from KDP before you publish for real. What looks perfect on screen can shift in print, colours especially, and a proof is the cheapest insurance you'll ever buy.

Common Cover Design Mistakes and How to Avoid Them

Even experienced authors fall into these traps. This list draws on published guidance from veteran cover designers, alongside broader industry commentary from Reedsy and Kindlepreneur.

  1. Ignoring the audience, designing a cover you love rather than one your readers expect. Fix: start with genre research every time.

  2. Overcomplicating the design, too many images, fonts, or effects fighting for attention. Fix: stick to one focal point. If removing an element doesn't hurt the cover, remove it.

  3. Poor font choices, hard to read or mismatched. Fix: limit yourself to two fonts and test readability at thumbnail size.

  4. Low-resolution images, pixelation reads as amateur instantly. Fix: use images at least 300 DPI at print size.

  5. Neglecting the spine and back cover, a blank spine or cluttered back cover quietly loses bookstore sales. Fix: design the full wrap, spine included.

  6. Failing to convey the book's essence, the cover feels generic or misleading. Fix: ask a stranger to guess the genre from the cover alone.

  7. Blindly copying trends, what works for one book won't automatically work for yours. Fix: understand why a trend works, then adapt it, don't just copy it.

  8. Skipping the thumbnail test, the single most common, costly mistake on this list. Fix: run it early and often.

  9. Ignoring contrast, text blending into the background. Fix: use a dark overlay on light images, or light text on dark.

  10. Skipping the proof, publishing without seeing a printed copy first. Fix: always order one before a full print run.

Expert Tip: Keep this list next to you while you design. Check off each item before you call the cover finished.

When and How to Hire a Professional Designer

Signs It's Time to Hire a Pro

DIY is empowering, but sometimes it's the wrong call. Bring in an expert if:

  • You've tried designing it yourself and, after multiple attempts, it still looks amateur.

  • Your genre demands polished, illustrated art, epic fantasy and children's books both fall into this bracket.

  • You're publishing a series and need a cohesive, branded look across multiple books.

  • You have the budget and want to give your book the strongest possible chance in a competitive market.

Expert Tip: A professional cover typically runs anywhere from around £150 to £1,200 or more, depending on complexity and the designer's experience. Treat it as an investment rather than an expense. A genuinely great cover can pay for itself many times over through increased sales.

How to Find the Right Designer

  • Reedsy Marketplace: vetted professionals with portfolios and reviews, filterable by genre.

  • Design contests: some platforms let several designers submit concepts so you can pick a winner from a shortlist.

  • Direct referrals: ask other authors in your genre who designed their covers, and whether they'd hire the same person again.

  • Design agencies and studios: Damonza, MiblArt, and NSP's own book cover design service offer fixed-price packages with designers who specialise by genre.

Product Recommendation: For a custom, professional cover without committing to the very top end of the market, look at design services with fixed packages and genre-specific designers. For higher-end illustrated work, established studios like MiblArt and Damonza are considered industry leaders.

Writing a Design Brief That Gets Results

A clear brief saves time and money. Include:

  1. Book title, subtitle, and author name.

  2. Genre and target audience, be specific ("YA fantasy with a romantic subplot, aimed at readers 16 to 25," not just "fantasy").

  3. Mood and tone, described in adjectives ("dark," "mysterious," "epic").

  4. Key imagery ideas, mention any symbols or scenes you picture, but stay open to the designer's own creative read.

  5. Three to five covers in your genre that you admire, with a note on what specifically you like about each.

  6. Technical specs: trim size, format (ebook, paperback, hardcover), and any platform requirements.

  7. Budget and timeline, be upfront about both.

If your story has a clear turning point or a defining emotional beat, it's worth naming it in the brief. A designer who understands the turning point in your story can often translate that single moment into the image or mood that anchors the whole cover, rather than working from genre labels alone.

Expert Tip: Trust the designer's expertise. You're hiring them for their eye and their market knowledge. Give clear feedback, but don't micromanage every pixel, that's usually where good briefs go wrong.

Plenty of authors find that once they test a few concepts with real readers, the cover that performs best isn't the one they instinctively liked most, a useful reminder that data tends to beat personal preference here.

Interactive Cover Design Checklist

Work through this list as you go. Tick off each item before you consider the cover finished.

  • Genre research: studied the top 20 bestsellers in my genre, noted the common colours, fonts, and imagery.

  • Mood board: built a mood board with 15 to 20 covers, colour swatches, and a vibe word.

  • Tool selection: chosen a design tool that matches my budget and skill level.

  • Canvas setup: set the correct dimensions for my format (ebook: 2,560 x 1,600 px; print: used the KDP template).

  • Image sourcing: selected high-resolution, commercially licensed images.

  • Background and imagery: placed background and main image with a clear focal point.

  • Typography: chosen genre-appropriate fonts, limited to two families, tested readability at thumbnail size.

  • Title and author name: placed with strong contrast, title is the largest element on the page.

  • Spine and back cover (print): designed the spine with title and author name, back cover has a blurb and barcode space.

  • Bleed and safe zones: extended the background 0.125" beyond the trim, kept text inside the safe zone.

  • Thumbnail test: resized the cover to 150 px wide, title and image both read clearly.

  • Feedback: gathered unbiased feedback from at least five strangers in my target audience.

  • A/B testing (optional): ran a low-cost ad test with two cover variants.

  • File export: exported the ebook cover as a high-quality JPEG (RGB), and the print cover as a PDF/X-1a (CMYK, fonts embedded).

  • Proof copy: ordered a physical proof (print) and reviewed it for colour, alignment, and clarity.

  • Final review: checked against the common mistakes list above, everything passes.

A quick-reference blueprint for three of the biggest categories. Use these as a starting point, then adjust for your specific subgenre and story.

Romance Cover Blueprint

  • Layout: a central couple, illustrated or photographic, often in a close embrace. Title at top or bottom, author name at the bottom.

  • Colour palette: warm reds, pinks, golds, and creams, high saturation throughout.

  • Typography: a flowing script for the title, paired with a clean serif or sans-serif for the author name.

  • Imagery: focused on emotional connection, faces visible, soft lighting, often a scenic backdrop like a beach or a sunset.

Thriller Cover Blueprint

  • Layout: bold, centred title, usually in all caps. An isolated figure or an abstract tension element, cracked glass, a long shadow. Dark background throughout.

  • Colour palette: black, deep blue, crimson, with high-contrast white or yellow text cutting through.

  • Typography: a heavy sans-serif for the title (Bebas Neue and Impact are common choices), a simple sans-serif for the author name.

  • Imagery: often a lone figure walking away, a car on an empty road, or a symbolic object like a knife or a clock. Clutter is the enemy here more than anywhere else.

Non-Fiction and Self-Help Cover Blueprint

  • Layout: title dominates the top half, usually large and bold. Subtitle below in smaller text. Author name at the bottom. Minimal imagery, icons or abstract shapes rather than photography.

  • Colour palette: bright, optimistic colours, yellow, orange, teal, against white or light backgrounds. High contrast throughout.

  • Typography: bold sans-serif for the title (Montserrat and Lato both work well), clean serif or sans-serif for the body text.

  • Imagery: simple icons, a lightbulb, an arrow, geometric shapes. Photography tends to date quickly here, so it's worth avoiding.

If you're still deciding which category your manuscript actually belongs in before you commit to a blueprint, our piece on the different types of books is a useful place to start.

Your Cover Is Your Book's Handshake

You've now walked through every step, from genre research to print-ready files.

Your cover doesn't need to be a work of art. It needs to stop the scroll, signal the genre, and make a promise your book actually keeps. Use the checklist. Test ruthlessly. Don't be afraid to iterate, the best covers are rarely born in a single draft.

If you're still unsure, go back and reread the section on hiring a professional. Sometimes the smartest move is investing in an expert rather than burning another weekend on a design that isn't quite landing. But if you're committed to doing it yourself, you now have the full toolkit to build a cover that stands shoulder to shoulder with a traditionally published title.

A cover is only ever the first handshake, though. The book still has to deliver on it, and the rest of the process matters just as much. At Northern Star Press, we work with authors across that whole journey: ghostwriting a manuscript that's still finding its shape, a full editing pass once the draft is done, and publishing the finished book properly. Once the cover's locked in, plenty of authors also add an audiobook production or a book trailer to carry that same genre promise across other formats.

Now go make your book impossible to scroll past.
