How big should your full
DAN VAU
How big should your full wrap cover file be?
Width = bleed + back cover + spine + front cover + bleed
Height = bleed + trim height + bleed
Example: 5 x 8 in paperback, 246 pages, white paper, B&W
Width: 0.125 + 5 + 0.554 + 5 + 0.125 = 10.804 in
Height: 0.125 + 8 + 0.125 = 8.25 in
KDP wants one single PDF with the back cover, spine and front cover as one image, at 300 DPI or higher.
Tip: use KDP's cover calculator to confirm your numbers before you export.
