Niche to published — in one studio

Most KDP publishers use 3–4 separate tools to do what Craftific.com does in one session. No InDesign license required.

  1. Find a KDP book niche Review Amazon autocomplete suggestions, BSR-based estimates, and asking-price context across KDP categories. Scores are estimates and do not establish search volume, sales, or margins. → Amazon autocomplete suggestions · BSR-based estimates
  2. Set your specs Choose your trim size (6×9", 8.5×11", 5×8", or others KDP supports), page count, and paper type. Spine width is calculated automatically from your page count and paper — no manual math. → KDP-supported trim sizes · Auto spine width
  3. Generate the interior PDF Lined pages, dot-grid spreads, guided journal prompts, planner layouts, habit trackers, sudoku, word search, crossword and maze puzzles with answer keys — exported as print-ready 300 DPI PDFs (puzzles as vector) with correct margins (0.375in inside, 0.25in outer), 0.125in bleed, and your chosen page count. → 300 DPI PDF · KDP margin spec · 0.125in bleed
  4. Design the cover Covers sized precisely to your page count — front panel, spine (at correct calculated width), and back panel. Choose from 10 vector cover styles or AI artwork, with your own colours and text. Download as a print-ready PDF or PNG. → 10 cover styles · Correct spine width
  5. Write the Amazon listing AI generates your KDP title, subtitle, 7 backend keywords, and a full book description formatted for Amazon search. Includes BISAC category suggestions and a 30-day launch checklist. → Title · Subtitle · 7 keywords · Description

Built to Amazon's actual KDP print specs — not approximations

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

AI-content declaration is your responsibility at publish time. KDP requires an internal declaration in your publishing dashboard — not buyer-facing. Craftific.com's output is a starting point you finalise and declare honestly.

  • Trim sizes match what KDP actually supports — 6×9", 8.5×11", 5×8", and others.
  • Spine width recalculates automatically when you change page count.
  • Interiors are real vector PDFs — not flattened image scans that fail KDP's quality check.

KDP Interior Templates for Low-Content Books

A KDP interior template is the page file you upload as your manuscript — lined, dot-grid, planner or logbook pages set to the exact trim size, margins and bleed KDP requires. Craftific.com generates them for every KDP trim size, including 6" × 9" and 8.5" × 11", with the inside gutter set for your page count, and exports a print-ready PDF.

Low-content book interior examples

  • Lined and dot-grid journals, gratitude and prompt journals
  • Daily, weekly and undated planners
  • Logbooks — reading, fitness, password, mileage, garden
  • Colouring pages and activity pages (single-sided)

KDP interior template in Canva vs a KDP generator

You can build interiors in Canva, but you have to set the trim size, bleed and gutter yourself and duplicate pages by hand. A KDP interior generator sets the specs automatically and repeats layouts across 100+ pages in seconds. Either way, size the cover with the KDP cover calculator once your page count is final.

What are examples of low-content books?

Journals, notebooks, planners, logbooks, sketchbooks, colouring books and many activity books — books whose pages are mostly repeated layouts or space for the reader to fill in.

Can I use Canva templates for Amazon KDP?

Yes, if the template's licence allows commercial use in products for sale and you set the exact KDP trim size, bleed and margins. Export as PDF Print for the interior.

KDP Interior Generator & Spine Width Tool: Frequently Asked Questions

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 every trim size KDP supports including 6×9" and 8.5×11".
How is the spine width calculated?
From your page count and paper type, using KDP's official spine-width formula. It recalculates automatically when you change your page count — so the front, spine, and back are always sized correctly before download.
What royalties can I earn from a low-content KDP book?
On Amazon.com, KDP pays 60% of list price on paperbacks priced $9.99 or more and 50% below $9.99, minus a printing cost based on page count and ink. A 120-page 6×9 black-ink journal ($2.44 to print) earns about $1.56 at $7.99 and about $3.55 at $9.99. Use the royalty calculator for your exact numbers.
Do I need to disclose AI-generated content to Amazon?
Yes. KDP's publishing form requires an internal declaration about AI-generated content — this is a checkbox in your KDP dashboard, not visible to buyers. Craftific.com's output is a starting point you edit and declare honestly when you publish.
Can I sell the same interior on Etsy as a printable download?
Yes. Craftific.com generates the interior and the listing for each platform separately. A KDP journal interior can also be exported as a printable PDF for Etsy with different sizing — two revenue streams from one design session.
