How To Design A Perfect Bound Book...
Use the below calculations to design your perfect bound book.
The spine width is equal to the text bulk plus .034”
Calculation: # of pages / PPI (pages per inch) = Text Bulk
Text Bulk + .034 = Spine Width
Example: (300/513ppi) = .584 Then .584+.034 =.618 (Spine Width)
B. Front/Back Cover Width
The width of your trim size.
C. Front/Back Cover Height
The height of your trim size.
D. Front/Back Cover Width
The bleed is extra cover to insure a proper trim so there is no white around the cover. The bleed is .125”.
E. Overall Height
Calculation: D+C+D = Overall Height
F. Overall Width
Calculation: D+B+A+B+D = Overall Width
