When an image crosses a paperback spread, design and review it as a spread but prepare the submission as individual pages. KDP requires single-page interior files rather than two-up spreads. Check the center relationship, page order, and relevant bleed settings in the exported file before approving the image treatment.
Decide what must remain visible across the center
A wide image can establish atmosphere or show a relationship that benefits from a spread. Identify which details carry its meaning before placing the center division. A face, label, or small object at the inner boundary may become difficult to read in the bound book even when the flat digital image looks complete.
For an illustrated landscape, the center might pass through open sky rather than a crucial building detail. Treat that as a composition decision supported by the image's purpose. Do not assume that any photograph can be cut in half without affecting the explanation or the reader's ability to recognize its subject.
Confirm the intended page pair
Identify the left and right pages in the actual reading sequence. A spread shown conveniently in the editing application may not correspond to the pages that face each other after front matter or blank pages are added. Review the full manuscript's pagination before treating the pair as fixed.
Record the image's location using stable section or figure identifiers as well as current page numbers. If the surrounding manuscript changes, those identifiers help locate the intended spread and reveal whether its two halves still face each other in the revised layout.
Prepare separate pages without losing the relationship
KDP's paperback guidance requires single-page files instead of spreads or two-up files. Use the layout application's appropriate export settings to produce individual pages while preserving the intended placement. Do not submit a wide spread merely because the design was reviewed in that view.
Inspect both exported pages together and separately. Confirm that the image halves correspond to the same approved source version and that no unintended scaling or displacement occurred during export. A visually continuous source spread does not establish that the individual output pages retained the same geometry.
Review bleed where the image reaches trim edges
If the image extends to the trimmed edge, use the current bleed requirements for the selected paperback layout. Check the actual exported page dimensions and the relationship between image coverage and the final trim. Keep this technical check separate from deciding what belongs near the inner binding area. If any interior page needs bleed, prepare the entire manuscript with the bleed setup and submit a print-ready PDF, rather than adding differently sized bleed pages to an otherwise no-bleed file.
Do not apply a remembered setting from a different project without reviewing the present book's specifications. Preserve the chosen trim, bleed setup, and export version in the production record. If one of those inputs changes, revisit the spread rather than assuming that the previous arrangement remains valid.
Test the bound reading experience
A flat screen preview cannot fully represent how a reader sees the inner part of a bound book. Use an appropriate physical review to examine important center details, continuity, and comfort of viewing. Record the observations with the specific layout version being assessed.
Avoid promising perfect alignment from a digital comparison alone. If the image's meaning depends on a tiny feature meeting precisely across the center, consider changing the composition or presenting the essential detail in a separate figure. The book should communicate reliably without requiring the reader to force the pages into an ideal flat arrangement.
Check the final sequence after all layout changes
Before handoff, confirm the page pair, the selected image version, captions, and any references in the surrounding prose. Review nearby blank pages and chapter starts that could have shifted the spread. A correct image export can still appear in the wrong relationship after a later pagination change.
Keep the editable spread layout and source image with the approved single-page publication file. That record lets a future editor adjust the book while preserving the intended relationship. The final check should establish both technical submission suitability and a readable image in context, rather than treating either one as proof of the other.
Frequently asked questions
Clear answers for this publishing decision.
Can I submit the image as one wide interior page?
KDP’s paperback guidance requires single-page interior files rather than two-up spreads. Prepare the individual pages and inspect how they work together in the actual book sequence.
Does a matching center on screen guarantee the printed result?
No. Review the bound reading experience appropriately and avoid making essential meaning depend on a tiny feature aligning perfectly at the inner boundary.
What should be rechecked after adding front matter?
Confirm that the intended left and right pages still form the correct facing pair. Revisit pagination, nearby blank pages, captions, and the actual exported sequence before approving the spread.
What must I check, disclose, and verify myself when AI helped produce the book?
Review facts, rights, and source material yourself, record which parts were AI-assisted or AI-generated so you can answer Amazon’s disclosure question accurately, and treat every automated check as a starting point rather than a verdict.
