No elevated permissions or background processes. Manual install & verification available. ### Genre Conventions Readers judge books by covers. Matching genre expectations is critical — a romance reader will skip a cover that looks like sci-fi, regardless of content. ### Fiction GenrePaletteImageryTypographyMoodThriller/MysteryDark (black, navy, blood red)Lone figure, urban scenes, shadowsBold sans-serif, all capsTense, ominousRomanceWarm (pink, red, gold, soft purple)Couples, flowers, scenic backdropsScript/cursive, elegant serifPassionate, dreamySci-FiCool (blue, teal, purple, silver)Space, tech, geometric shapesClean sans-serif, futuristicVast, technologicalFantasyRich saturated (emerald, crimson, gold)Swords, magic, landscapes, creaturesDecorative serif, ornamentalEpic, magicalLiterary FictionMuted, sophisticatedAbstract, minimal, symbolicElegant serif, understatedThoughtful, artisticHorrorDark with high contrast popsFaces, shadows, isolation, decayDistressed, bold, drippingDread, uneaseHistoricalSepia, muted period-accuratePeriod clothing, architecture, artifactsClassical serifNostalgic, authentic ### Non-Fiction CategoryStyleImageryTypographyBusiness/Self-helpClean, bold, 2-3 colorsMinimal or none, icon optionalLarge bold sans-serif titleMemoirPersonal, warmAuthor photo or atmospheric sceneMix of serif and sansScience/AcademicProfessional, structuredDiagrams, abstract visualsClean serif, structured layoutCookbookAppetizing, brightHero food photographWarm, inviting fontsTravelVibrant, aspirationalDestination photographyAdventure-style fonts ### Print (Trim Sizes) FormatDimensionsCommon ForMass market paperback4.25 x 6.87"Genre fictionTrade paperback5.5 x 8.5"Most fiction/non-fictionStandard6 x 9"Non-fiction, textbooksLarge format7 x 10"Coffee table, art books ### Digital PlatformCover SizeAspect RatioAmazon Kindle2560 x 1600 px (min 1000 x 625)1.6:1Apple Books1400 x 1873 px minimum~3:4General ebook2500 x 3750 px2:3 ### Spine Width Approximate: page count / 400 = spine width in inches (varies by paper stock). 200 pages ≈ 0.5" spine 400 pages ≈ 1.0" spine ### Layout Zones ┌─────────────────────────┐ │ TITLE ZONE │ ← Top 1/3: Title must be readable here │ (largest text) │ This is what shows in thumbnails │ │ │ │ │ MAIN IMAGE │ ← Middle: Core visual/illustration │ ZONE │ The emotional hook │ │ │ │ │ SUBTITLE / │ ← Bottom area: Author name, subtitle │ AUTHOR ZONE │ Smaller text, less critical at thumbnail └─────────────────────────┘ ### The Thumbnail Test Your cover will be seen at 80x120px on Amazon, 60x90px in search results, and ~40x60px on mobile grids. At thumbnail size, readers must be able to identify: The genre (from color and composition) The title (if large enough) The mood (from imagery) Test: shrink your cover to 80px wide. If you can't read the title or identify the genre, redesign. ### Thriller infsh app run falai/flux-dev-lora --input '{ "prompt": "dark cinematic book cover scene, silhouette of a person standing before a foggy bridge at night, single streetlamp casting long shadows, noir atmosphere, high contrast, desaturated blue tint, dramatic tension", "width": 832, "height": 1248 }' ### Romance infsh app run bytedance/seedream-4-5 --input '{ "prompt": "romantic soft-focus scene, couple silhouetted against golden sunset on a beach, warm pink and gold tones, bokeh lights, dreamy atmosphere, soft pastel sky, intimate mood", "size": "2K" }' ### Sci-Fi infsh app run falai/flux-dev-lora --input '{ "prompt": "science fiction book cover art, massive space station orbiting a ringed planet, deep blue and teal color palette, stars and nebula background, hard sci-fi aesthetic, cinematic scale, clean geometric architecture", "width": 832, "height": 1248 }' ### Fantasy infsh app run xai/grok-imagine-image-pro --input '{ "prompt": "epic fantasy book cover illustration, ancient stone castle on a cliff overlooking a misty valley, magical aurora in the sky, rich emerald and gold colors, detailed environment, sense of wonder and adventure", "aspect_ratio": "2:3" }' ### Non-Fiction / Business infsh app run falai/flux-dev-lora --input '{ "prompt": "minimal abstract book cover background, clean gradient from deep navy to white, subtle geometric pattern, professional and modern, negative space, corporate aesthetic", "width": 832, "height": 1248 }' ### Typography Rules AI cannot render text reliably. Generate the cover art/background with AI, then add typography in a design tool. ### Title Hierarchy Title — largest, most prominent, top 1/3 of cover Subtitle — smaller, below title or at bottom Author name — bottom of cover, size depends on author recognition ### Font Pairing by Genre Thriller: bold sans-serif title + condensed sans-serif author Romance: script/cursive title + elegant serif author Sci-Fi: geometric sans-serif for both Fantasy: decorative/medieval serif title + clean serif author Business: heavy bold sans-serif title + light sans-serif subtitle ### Iteration Workflow # 1.
