Frequently Asked Questions
What are the official Amazon KDP eBook cover dimensions?
The ideal dimensions for an Amazon Kindle Direct Publishing (KDP) eBook cover are 1,600 x 2,560 pixels with an aspect ratio of 1:1.6 (or minimum 1,000 x 1,600 pixels). This tool automatically designs at high-resolution 1,600 x 2,560 to ensure sharp rendering on Kindle Paperwhite, Kindle Scribe, and high-DPI smartphone screens.
How does the spine thickness calculator work for paperback wraps?
Spine thickness depends on page count and paper type. Amazon KDP uses 0.002252 inches per page for standard white paper and 0.0025 inches per page for cream paper. Our built-in calculator automatically converts your page count (e.g. 350 pages) into exact spine width in inches, millimeters, and pixels.
Can I use these book covers for commercial publishing on Amazon and Apple Books?
Yes, 100%. All covers generated with Checkistan eBook Cover Maker are royalty-free with no attribution required. You have full commercial ownership to publish your covers on Amazon KDP, Barnes & Noble Press, Kobo Writing Life, IngramSpark, Smashwords, or Wattpad.
Can I export a 3D book mockup with a transparent background for marketing?
Yes! The 3D Mockup tab features Hardcover, Angled Paperback, Floating Book, and Tablet E-Reader styles. You can export directly with a transparent PNG background, allowing you to drop the 3D book directly into Facebook ads, Instagram carousels, Kickstarter campaigns, or your author website.
Can I upload my own custom background illustration or author photo?
Yes. You can drag and drop any PNG, JPEG, or WebP artwork. The editor provides controls for zoom, positioning, opacity, blur, brightness, and darkening overlays so your title and author typography remain legible.
Are there any watermarks or hidden fees on downloaded book covers?
None whatsoever. Every book cover, full paperback wrap, and 3D mockup you export is 100% watermark-free, unbranded, and commercial-ready at full 300 DPI resolution. Unlike other cover generators, there are no locked features, watermarks, or credit paywalls.
Do I need to create an account or provide a credit card to download?
No. Checkistan eBook Cover Maker is completely open and free with no sign-up, registration, or credit card required. You can design, preview, and download your book cover instantly in your browser.
Is my uploaded book art and unpublished manuscript private?
Yes, 100% private. All canvas rendering, typography styling, and image processing happen directly inside your web browser. Your unpublished book titles, synopsis drafts, and original artwork are never uploaded to our servers or exposed to third parties.
Does this tool generate an ISBN barcode for the back cover?
Yes! In Full Paperback Wrap mode, the back cover includes a generated EAN-13 ISBN barcode box complete with price tag and safe margin boundaries according to print publication standards.
