SpineReady: Book Cover Templates for Every Platform

SpineReady is the complete self-publishing toolkit for authors who want to get their book cover right the first time — every time.

 Most authors waste hours hunting across platform websites trying to piece together bleed requirements, spine widths, safe zones, and barcode placement. Then they upload and get rejected anyway. SpineReady eliminates that entire process. Enter your book specs once. Get everything you need in seconds. Completely offline, no account, no subscription — ever. 

── PRINT COVER TEMPLATES ── 

Choose your platform, enter your trim size, page count, and paper type — and SpineReady generates a precise, fully labeled cover template showing every zone: Full Cover, Front, Back, Spine, Safe Area, Bleed, Margins, and Barcode placement. Export as PNG, SVG, or PDF. Supports Amazon KDP, IngramSpark, Barnes & Noble Press, Draft2Digital, and Lulu Press.

 ── SPINE WIDTH CALCULATOR ──

 No more guessing. SpineReady calculates your exact spine width based on your page count, paper type (white or cream), interior type (B&W or color), and binding — down to the thousandth of an inch. It even tells you how many characters fit on your spine at standard font sizes. 

── COST & ROYALTY CALCULATOR ──

 Know your numbers before you publish. Enter your list price and book specs and instantly see printing costs, royalties per sale, break-even point, and projected annual profit across Amazon KDP, IngramSpark, Barnes & Noble Press, and Lulu — side by side. Stop leaving money on the table by publishing on the wrong platform. 

── 3D COVER MOCKUP GENERATOR ── 

See your book as a physical object before it goes to print. Generate a realistic 3D render with accurate spine thickness, customize colors and text, rotate to any angle, and export as a high-resolution PNG for your author website, Amazon listing, or social media. No external software needed.

 ── COVER VALIDATOR ── 

Run a pre-flight check before you upload. The Cover Validator instantly flags errors that would cause rejection (wrong dimensions, low resolution, incorrect aspect ratio), warns you about thin spines and font size risks, and gives you platform-specific tips on color mode, file format, and safe zone compliance. Know you're ready before you hit submit.

 ── DESIGN STUDIO ── 

Lay out your cover directly on a dimension-accurate canvas sized to your exact book specs. Add text and image layers, toggle bleed and safe zone overlays, manage layers, and export as PNG. Perfect for planning your layout before handing off to a designer.

 ── EBOOK COVERS ── 

Get the exact pixel dimensions for your ebook cover on every major platform and export a correctly sized blank template, ready for your designer or Canva.

 ── PLATFORM COMPARISON ── 

Compare full cover dimensions, spine widths, bleed, and barcode requirements across all platforms simultaneously for your exact book specs — in inches, millimeters, or centimeters.

 ── DUST JACKET SUPPORT ── 

Full dust jacket layout for hardcover books, including hinge, wrap, and flap calculations. Supports Amazon KDP and IngramSpark.

 ── BATCH GENERATE ── 

Configure multiple books and export a single multi-page PDF with all cover templates in one file. Perfect for cover designers managing multiple projects at once. 100% offline. No internet required. No subscription. No account. No data sent anywhere. Open the app and get to work.
