KDP Full Wrap Cover Size Calculator
Enter your trim size, page count, and paper type to get the exact full wrap cover dimensions, front, spine, back, and bleed combined into one canvas size.
This is your canvas size before you generate Amazon's actual cover template file, always cross-check against KDP's own cover calculator before submitting final artwork.
Common questions
How do I calculate my full wrap cover size?
Width = (trim width × 2) + spine width + (bleed × 2). Height = trim height + (bleed × 2). Bleed is 0.125" per side.
Does the cover need bleed on all sides?
Yes, 0.125" on the top, bottom, and outer edges, since the artwork extends past the trim line.
Do I need to build my own cover template?
Amazon's own cover calculator generates a precise template once you know trim size, page count, and paper type. These numbers should match it, but always generate and use Amazon's actual template for final artwork.
Why this matters
Get the canvas size wrong and your cover text can shift off-center or get cut off at print. Knowing the real dimensions before you open your design software saves a redo.
KDP Workspace's free Interior Assembler calculates spine width and margins together, so your cover and interior always line up.
