Designing this cover
- Build the cover canvas at 14.453 x 10.25 in — or 4,336 x 3,075 px at 300 ppi.
- The back cover runs from the left edge to 7.125 in; the spine from 7.125 to 7.328 in; the front cover after that.
- Spine text is allowed — centre it and keep 0.0625 in clear on each side.
- Keep titles and faces at least 0.25 in inside the trim; KDP places the barcode in a 2 x 1.2 in area at the lower right of the back cover.
- Export as a flattened PDF (PDF/X-1a is safest) with fonts embedded.
