Designing this cover

  • Build the cover canvas at 13.173 x 9.25 in — or 3,952 x 2,775 px at 300 ppi.
  • The back cover runs from the left edge to 6.125 in; the spine from 6.125 to 7.048 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.
