Complete KDP Cover Design Checklist: 25 Quality Control Points

Technical Specifications

Critical: Check file dimensions match your trim size exactly
Wrong dimensions cause automatic rejections. Use KDP's cover calculator for precise measurements including spine width.

Critical: Verify 300 DPI resolution minimum
Low resolution creates pixelated covers that hurt credibility. Your file should be 300 DPI at actual print size, not scaled up.

Critical: Include 0.125" bleed on all edges
Without proper bleed, white edges appear on printed books. Extend your background colors and images past the trim line.

Critical: Keep text 0.25" from trim edges
Text too close to edges gets cut off during trimming. This safety margin is non-negotiable for readability.

Recommended: Use CMYK color mode for print
RGB colors shift dramatically in print. Convert to CMYK to see how your colors will actually look on paper.

Recommended: Save as high-quality PDF or TIFF
JPEG compression artifacts become visible in print. Use lossless formats for professional results.

Optional: Create separate files for ebook and print
Ebook covers can use brighter colors and finer details that don't translate well to print.

Visual Design Elements

Critical: Ensure title reads clearly at thumbnail size
Most customers see your cover as a 150px thumbnail first. If they can't read your title, they won't click.

Critical: Use genre-appropriate color schemes
Romance uses pastels and reds, thriller uses dark colors, self-help uses blues and whites. Wrong colors confuse browsers.

Critical: Make author name legible but not competing with title
Unless you're a bestselling author, your name should be smaller than the title but still readable.

Recommended: Choose fonts that match your genre
Script fonts for romance, bold sans-serif for business books, decorative fonts for fantasy. Typography signals genre instantly.

Recommended: Use high-contrast elements
Light text on dark backgrounds or dark text on light backgrounds. Avoid medium contrasts that disappear in thumbnails.

Recommended: Limit color palette to 2-3 main colors
Too many colors create visual chaos. Professional covers use restrained palettes with one accent color.

Optional: Include subtle texture or gradient
Flat colors can look amateur, but overdone effects look dated. Subtle depth adds professionalism without distraction.

Marketplace Optimization

Critical: Research competitor covers in your category
Your cover needs to fit the category while standing out. Spend 30 minutes browsing bestsellers in your genre.

Critical: Avoid copyrighted images or fonts
Use only licensed stock photos or royalty-free images. Copyright violations can get your book removed permanently.

Recommended: Consider series branding consistency
If planning multiple books, establish visual elements (fonts, color schemes, layout) that work across titles.

Recommended: Test cover with target demographic
Show your cover to 5-10 people in your target audience. Ask what genre they think it is and if they'd click on it.

Optional: Create variations for A/B testing
KDP doesn't allow split testing, but you can test different covers on social media or with beta readers before launch.

Optional: Design for international markets
If targeting global markets, ensure your cover works across cultures. Some colors and symbols have different meanings internationally.

Quality Control Final Check

Critical: Spell-check all text elements
Typos on covers are deal-breakers. Check title, subtitle, author name, and any back cover text multiple times.

Critical: Verify spine text reads bottom to top
This is industry standard. Text should read correctly when the book is lying face-up with the spine visible.

Critical: Check back cover layout and barcode space
Leave space for KDP's barcode (2" x 1.2" in bottom right). Include compelling book description and author bio.

Recommended: Review on multiple devices and screens
Colors and clarity vary between monitors. Check your cover on phone, tablet, and computer screens.

Recommended: Compare final file to original design
File compression and conversion can shift colors or blur text. Always compare your uploaded file to your original design.

Optional: Get professional feedback
Invest in a professional cover designer's critique if this is your first cover or if sales are disappointing.

Common Oversights Authors Skip

1. Not checking spine width calculation: Spine width changes with page count. Recalculate if you add or remove pages.

2. Forgetting to embed fonts: If fonts aren't embedded, KDP substitutes default fonts, ruining your design.

3. Using RGB instead of CMYK for print: Your vibrant screen colors will look dull and muddy in print.

4. Ignoring genre conventions: A literary fiction cover that looks like a romance will attract wrong readers and get negative reviews.

5. Not testing readability at small sizes: Your beautiful detailed cover becomes unreadable as a thumbnail, losing potential sales.
