❌ Don't: Key elements of the design extend beyond the Crop/Wrap line.
When designing your cover, you will see colored guideline borders that represent critical print boundaries. These lines help you place content correctly so nothing important gets trimmed, wrapped, or misaligned during production.
Each guide indicates a different area:
🟣 Purple line — Bleed area
Background images should extend past this line so your cover prints edge-to-edge.
🔴 Red line — Trim / Wrap line
This is where the cover will be cut or wrapped. Important elements should never cross this boundary.
🟢 Green line — Safe area
All critical content such as text, faces, and logos should stay inside this zone.
⚫ Dotted line — Spine area
Indicates where the cover folds around the spine.
Always extend background images past the red trim line.
If your design stops before this line, your printed cover may show unwanted white edges after trimming.
If important content falls outside the safe area or inside trim/wrap zones, adjust your layout before printing.
Reprints cannot be issued for user-created design errors. If you are unsure whether your cover is safe to print, contact support before ordering.
All critical elements must be positioned at least 1/8 inch inside the safe area boundary.
This includes:

Anything placed too close to edges risks being cut off or wrapped around the book.

Confirm placement visually before finalizing
Text boxes align based on the box dimensions, not the text itself.
For precise centering:
Adding or removing pages changes spine width and can shift cover positioning.
Any time your page count changes:
This prevents misaligned titles or artwork.
The back cover is valuable design space. Consider using it for:
