KDP cover creator with the spine math built in.
KDPify builds your full-wrap cover — front, spine and back — at the exact measurements KDP asks for, typesets your title in beautiful display fonts, and exports a print-ready cover PDF that passes KDP's previewer the first time.
Covers that land where KDP expects them
The cover preview shows KDP's trim, safe area and spine guides while you place the title, subtitle and author.
- Spine width from page count and paper type
- Title, subtitle and author set by the app, never misspelled by the AI
- Back cover drawn to match the front
- Room left for KDP's barcode
The KDP cover calculator, built into the editor
Stop stitching together a cover template, a ruler and the KDP cover calculator. KDPify applies the same measurements automatically while you design.
Exact spine width
The spine is computed from your page count and paper type, and checked against Amazon's own cover calculator, so it matches what KDP expects.
Trim, bleed and safe-area guides
KDP's trim line, bleed and safe area stay on screen while you place the title, subtitle and author — nothing drifts into the cut zone.
Titles typeset by the app
Your title, subtitle and author name are typeset by the app in beautiful display fonts, so the text is never misspelled by the AI.
AI-drawn cover artwork
Draw the cover art with your own ChatGPT or Gemini account, even a free one. Not happy with it? Describe the change and it is redrawn.
A back cover that matches
The back cover is drawn to match the front, so the whole wrap reads as one finished book.
Room for KDP's barcode
A clear area is left in the right spot on the back cover, exactly where KDP places its barcode.
How a cover comes together
Four steps, and the spine sizing happens on its own.

Questions
Does KDPify replace the KDP cover calculator?
You do not need the calculator separately. KDPify applies the same measurements automatically: it computes the spine width from your page count and paper type and checks the result against Amazon's own cover calculator, so the cover PDF matches what KDP expects.
Can the AI draw the cover art?
Yes. KDPify draws the front cover artwork with your own ChatGPT or Gemini account, even a free one, and draws the back cover to match the front. Your title, subtitle and author name are typeset by the app, never by the AI, so the text is never misspelled.
Is the cover PDF print-ready?
Yes. The exported PDF is a full-wrap cover at your exact trim size, with bleed, the safe area on each side of the binding, a spine sized from your page count and paper, and room left for KDP's barcode.
