How to calculate book spine thickness and create a book cover.
Need to know your page size?
Example for a 5.5 x 8.5 book:
96 page paperback book printed on 120gsm paper
Paperback Book Front Cover
Width: 5.5"
Height: 8.5"
(+.125" on outside, top and bottom edges for image bleed, if cover art bleeds)
Paperback Book Back Cover
Width: 5.5"
Height: 8.5"
(+.125" on outside, top and bottom edges for image bleed, if cover art bleeds)
Paperback Book Spine Thickness
Width = 8.27mm (See Spine Thickness Calculator below)
Height: 8.5"
(+.125" on top and bottom edges for image bleed, if cover art bleeds)
Now add all the horizontal measurements for width:
5.5" back cover + 8.27mm spine + 5.5" front cover = 11.326" width
Height: 8.5"
The final page size of your document would be 11.326" wide x 8.5" high
