SpineReady
Book Cover Templates, Perfected
Stop guessing your spine width. SpineReady calculates your exact cover dimensions for every major publishing platform and generates a professional, print-ready template — in seconds, completely offline.
Choose from KDP, IngramSpark, Barnes & Noble Press, or Draft2Digital — each with its own precise specifications
Cover Rejections Kill Launch Days
Every platform has its own rules: different bleed sizes, barcode placement zones, spine width formulas that change based on page count and paper type. Getting it wrong means rejected uploads, redesign costs, and missed launch dates.
Instant Spine Calculation
Enter your page count and paper type. SpineReady applies each platform's official formula and shows your exact spine width immediately — no spreadsheets, no guessing.
Every Zone, Labeled & Measured
Generated templates show all critical zones — Full Cover, Front Cover, Back Cover, Spine, Safe Area, Bleed, Margins, and Barcode Area — with exact measurements in your chosen unit.
Side-by-Side Platform Comparison
Publishing wide? Compare all platforms at once to see exactly how your cover specs differ — so your designer creates one file that works everywhere.
Ebook Covers Included
Not just print. SpineReady also provides the exact pixel dimensions your ebook cover needs for every supported platform, with aspect ratio guidance built in.
Your Exact Spine Width in Seconds
Every platform calculates spine width differently. KDP uses pages × paper thickness; IngramSpark has its own formula; B&N Press has yet another. SpineReady knows all of them and applies the right one automatically the moment you enter your specs.
Get Ebook Dimensions Right Too
Ebook covers aren't guesswork either. Each platform recommends specific pixel dimensions and aspect ratios. SpineReady shows the recommended size for Amazon KDP, IngramSpark, Barnes & Noble Press, and Draft2Digital so your cover looks sharp on every device and storefront.
See Every Platform at Once
Going wide with your book? The Compare view shows all platforms side by side with the same trim size and page count so you and your designer can see exactly how the cover specs differ before a single file is opened in Photoshop or Affinity.
Every Major Publishing Platform
SpineReady is built specifically around the requirements of the four platforms most self-publishing authors use — with print and ebook cover support for each.
All zones are drawn with exact measurements in your chosen unit (in / mm / cm) so your designer or cover tool can place every element with precision.
