In Graphic Mode, you can pair two facing pages into a double-page spread—a single double-wide canvas that spans the left (verso) and right (recto) pages of an open physical book. Double-page spreads are essential for panoramic children's picture books, comic splash reveals, and illustrated maps.

Which projects support spreads

Double-page spreads are available on print-proportioned graphic formats—such as Square (8 x 8"), Children's Portrait (8 x 10"), Children's Landscape (10 x 8"), US Comic (6.625 x 10.25"), Graphic Novel (6 x 9"), and Manga.

Vertical-scroll Webtoon projects do not use spreads, because readers view them on a single continuous phone column rather than facing pages (see Creating a webtoon in Graphic Mode).

How facing pages pair in a real book

Physical books follow fixed left-and-right pagination among your story pages (excluding front/back covers and spine):

• Page 1 (left) + Page 2 (right) form the first facing pair, Page 3 (left) + Page 4 (right) form the next, and so on.
• When you convert a page into a spread in the left-hand page list, BookZeta pairs it with its facing partner and opens a double-wide canvas (2x your single-page width at the same height) owned by the left-hand page.
• You can split a spread back into two separate single pages—or restore an earlier snapshot from version history—at any time.

Designing safely across the centre gutter

The middle vertical line of a spread is not a flat crease; in a bound paperback or hardcover, glue and paper curvature pull the centre of both pages inward toward the spine. Keep three layout habits in mind:

1. Never put faces, eyes, or key details dead-centre. Place characters comfortably on either the left third or the right third of the spread, letting scenery, sky, water, or motion lines cross the middle fold.
2. Never run a text box or speech bubble across the centre line. Keep sentences and speech bubbles wholly on the left page or wholly on the right page, well inside the inner safe margin.
3. Extend backgrounds all the way to the outer bleed guides. Spreads almost always look best full-bleed—make sure your background fills the entire double-wide canvas past the trim line so no white border shows after trimming.

How spreads export across formats

You only design the spread once; BookZeta adapts it to each destination when you open Publish & Export:

• Print PDF: BookZeta slices the double-wide spread cleanly into its left and right interior pages with proper outer bleed and no accidental inside-spine bleed on KDP exports. See Choosing trim sizes, gutter margins, and bleed.
• Online reader & screen exports: Readers see the panoramic artwork preserved as intended, and read-along audio stays synchronized with the page order.
