Built to Amazon's actual KDP print specs

Low-content books get rejected at upload when margins, bleed or spine width are off. Every interior and cover here is generated against KDP's published spec: 0.375in inside margin, 0.25in outer margin, 0.125in bleed, and spine width calculated from your real page count and paper type.

  • Trim sizes match what KDP actually supports, including 6"×9" and 8.5"×11".
  • Spine width is recalculated automatically when you change page count.
  • AI-content declaration is your call at publish time — the output is a starting point, not a final file.

Questions publishers ask

Do the interiors meet Amazon KDP's print specs?
Yes. Interiors are generated with KDP's required margins (0.375in inside, 0.25in outer) and 0.125in bleed, in the trim sizes KDP supports, including 6"×9" and 8.5"×11".
How is the cover spine width calculated?
From your page count and paper type, using KDP's spine-width formula, so the front, spine and back are sized correctly before you upload.
Do I need to disclose AI-generated content to Amazon?
Yes. KDP's publishing form requires you to declare whether a book contains AI-generated content — an internal declaration in your KDP dashboard, not buyer-facing. Templifier's output is a starting point you finalise and declare honestly when you publish.
What interior types can be generated?
Lined, dot-grid, planner, maze and puzzle interiors, rendered as real vector PDFs with selectable text rather than flattened images.
Is the royalty estimate accurate?
It's a projection based on your price, page count and marketplace using KDP's published royalty formulas — useful for planning, but your actual payout depends on KDP's final calculation at publish time.
Can I publish the same book on KDP and sell it as a printable too?
The interior and listing content are generated separately per workflow, so you can adapt a KDP book into a printable version — each platform's formatting and licensing rules still apply.
