How to Make a Book Cover (Free, Print-Ready)

To make a book cover, work out your trim size and page count first, set up a canvas with the correct spine width and bleed, then design front, spine, and back as one wrap. Canva and other tools handle the layout — but getting the dimensions wrong is the mistake that gets a cover rejected by printers.

Get the numbers right before you design

A book cover isn’t a poster. It’s a wrap covering the back, spine, and front. Three measurements decide everything:

MeasurementWhere it comes from
Trim sizeThe finished page size — e.g. 6″ × 9″, 5.5″ × 8.5″, A5
Page countDetermines spine width
Spine widthPage count × paper thickness

Spine width formula (approximate):

So a 200-page black-and-white book on cream paper has a spine of about 0.5 inches. Don’t guess — most print services publish a spine calculator.

Where you’re publishing decides the specs

PlatformWhat it gives you
Amazon KDPA free cover template calculator (enter trim size + page count)
IngramSparkDownloadable cover template
Traditional printerUsually supplies a template — always ask
Ebook onlyNo spine, no bleed — just the front at 1600 × 2560 px for Kindle

Use the template. Every serious print service gives you a downloadable file with the exact spine, bleed, and safe zones marked. Designing without it is how covers get rejected.

Step by step (Canva)

  1. Get the template first. Download your print service’s cover template, or note the full wrap dimensions (back + spine + front + bleed).
  2. In Canva, Create a design → Custom size, and enter the full wrap dimensions in mm or inches.
  3. Import the template as an image and drop it on the bottom layer at exactly 100% size.
  4. Add guides at the fold lines so you know where the spine and both covers begin.
  5. Design the front cover first — this is what sells the book. Then the spine (title + author, readable when shelved), then the back (blurb, barcode area, author bio).
  6. Keep text inside the safe zone — at least 5 mm from the trim edge and clear of the spine.
  7. Export as PDF Print with the bleed included.

Don’t delete the template layer until you’re done. It’s your only reference for where the fold and trim lines fall.

Common reasons a cover gets rejected

ProblemWhy
Wrong spine widthPage count changed after the cover was made
Text outside the safe zoneIt gets trimmed off in production
No bleedWhite edges appear on the printed cover
Low-resolution imageBelow 300 dpi — prints visibly blurry
Wrong colour modeCanva’s PDF Print can export CMYK (choose the CMYK profile on download — paid plans); RGB files are converted by most printers
Barcode area occupiedThe printer can’t place the ISBN

Check every one of these before uploading. Print services reject covers automatically for most of them.

FAQ

How do I make a book cover for free?

Use Canva — set a custom size matching your full wrap, import your printer’s template as a guide, design, and export as PDF Print.

How do I work out the spine width?

Multiply the page count by the paper thickness — about 0.0025″ per page for cream paper, 0.002252″ for white. Or use your print service’s spine calculator, which is safer.

What size should a book cover be?

It depends on your trim size and page count. A 6″ × 9″ paperback with 200 pages needs a wrap of roughly 12.75″ × 9.25″ including spine and bleed. Always use the printer’s template.

Should I design the spine and back too?

For print, yes — a printed cover is one wrap file containing back, spine, and front. For an ebook, you only need the front.

Can I use Canva for Amazon KDP covers?

Yes. Set the canvas to KDP’s wrap dimensions, keep text inside the safe zone, and export as PDF Print with bleed. Download KDP’s cover template first so the spine width is exact.
