KDP hardcover wraps have additional bleed, hinge, and turn-in allowances because the case binding wraps around a rigid board. The spine width is also calculated differently because the case board adds thickness beyond the paper block. SleekPixel handles those adjustments automatically in the hardcover template.

KDP currently supports case laminate hardcover, which prints the cover art directly on the hardcover binding. SleekPixel templates render to the case laminate spec. Dust jackets are a separate file format that KDP does not currently offer through their print-on-demand service for self-published authors at this time.

Yes, because both pull from the same WordPress book post fields. The title, author, description, and ISBN are shared between the two wrap templates, so the hardcover and paperback editions stay aligned automatically without separate maintenance per binding format from the WordPress source.

Hardcover spine width is calculated from the page count and the case binding allowance, which differs from the paperback spine math. SleekPixel templates accept a binding type parameter on the book post, so the spine width adjusts automatically for hardcover versus paperback wraps from the same source.

Yes. KDP hardcover supports a range of trim sizes including 6x9, 5.5x8.5, and 6.14x9.21. SleekPixel templates accept the trim size as a parameter on the book post, so the wrap renders at the correct dimensions for whatever trim the hardcover edition is bound to in KDP.

The ISBN barcode placement on a hardcover wrap is similar to the paperback but accounts for the back board allowance and turn-in. SleekPixel reserves the barcode safe zone in the hardcover template at the KDP-required position, so the wrap passes the automated cover validation on submission.

Yes. SleekPixel renders Kindle eBook, paperback, and hardcover wraps from the same WordPress book post. A multi-format launch ships with all three covers ready on day one, with the same identity carried across digital, paperback, and hardcover formats consistently for every reader who buys.

Adjust the SleekPixel template parameters to match the new spec and re-render. Because the template is dynamic and tied to book post fields rather than a static design, the migration is a template update, not a per-book redo across every hardcover wrap the author has ever published with KDP.
