KDP cover calculator and template generator

A 6 × 9 in, 100-page KDP paperback on white paper needs a 12.475 × 9.25 in cover: one flat PDF with bleed, back cover, spine, front cover and bleed. Its width is 0.125 in + trim width + spine + trim width + 0.125 in and its height is the trim height + 0.25 in; at 200 pages the same book needs 12.7 × 9.25 in. Download the template as a 300 DPI PNG or an SVG.

The paperback cover formula

KDP prints the cover on one sheet that wraps around the book (a full-wrap cover), so your file must include the back cover, the spine and the front cover side by side, plus 0.125 in of bleed on every outside edge. The bleed is trimmed off after printing; it only exists so that the art reaches the edge of the finished book.

Hardcover covers

KDP hardcovers are case laminate: the printed cover is glued around rigid boards. Instead of bleed, the file has a 15 mm wrap on every edge that folds around the boards. Each board is 5 mm wider and 6 mm taller than the trim, and a 10 mm hinge next to the spine must stay free of text and barcodes. The spine gets an extra 4.8 mm.

KDP’s help page quotes a slightly smaller wrap than its own cover calculator. We follow the calculator (0.591 in), which is what KDP’s downloadable templates are built from.

Safe areas and the barcode

  • Keep text and faces at least 0.125 in inside the trim on a paperback, and 0.125 in inside the board edge on a hardcover.
  • Keep spine text 0.0625 in away from each fold. Spine text needs a book with more than 79 pages.
  • Leave the 2 × 1.2 in barcode area in the lower right of the back cover empty; KDP adds the ISBN barcode there when you don’t supply your own.
  • Text must be at least 7 pt. Avoid thin borders: if you use one, keep it 0.25 in or more inside the trim.

Exporting the PDF

Export one single-page PDF at the full cover size, with images at 300 DPI and fonts embedded. Hide or delete the template layers first: KDP rejects covers with visible guides, crop marks or placeholder text. Keep the file under 40 MB if you can.

How to use it

  1. 01

    Choose the binding

    Paperback covers have bleed; hardcover covers have a wrap that folds around the boards.

  2. 02

    Choose trim and paper

    Use the same trim size and ink/paper you will select in KDP.

  3. 03

    Enter the final page count

    The spine, and so the whole cover, depends on it.

  4. 04

    Download the template

    Use the 300 DPI PNG in Canva or the SVG in Illustrator, Affinity or Inkscape, design over it, hide the guides and export a single-page PDF.

Questions

What size is a KDP cover for a 6 × 9 inch paperback?

It depends on the page count and paper. With 200 pages on white paper the spine is 0.45 in, so the full cover is 12.7 × 9.25 in: 0.125 in bleed + 6 in back + spine + 6 in front + 0.125 in bleed, by 9 in + 0.25 in.

What is the KDP cover size for a 6 × 9 in paperback with 100 pages?

On white paper: 12.475 × 9.25 in (3,743 × 2,775 px at 300 DPI), with a 0.225 in spine. On cream paper: 12.5 × 9.25 in (3,750 × 2,775 px at 300 DPI), with a 0.25 in spine.

What is the KDP cover size for a 6 × 9 in paperback with 300 pages?

On white paper: 12.926 × 9.25 in (3,878 × 2,775 px at 300 DPI), with a 0.676 in spine. On cream paper: 13 × 9.25 in (3,900 × 2,775 px at 300 DPI), with a 0.75 in spine.

What is the KDP cover size for an 8.5 × 11 in paperback with 100 pages?

On white paper (black and white interior): 17.475 × 11.25 in (5,243 × 3,375 px at 300 DPI), with a 0.225 in spine.

What cover size does a 32-page 8.5 × 8.5 in picture book need?

With a premium color interior: 17.325 × 8.75 in (5,198 × 2,625 px at 300 DPI), with a 0.075 in spine. It can't have spine text: KDP prints it only on books with more than 79 pages.

What resolution should a KDP cover be?

300 DPI. For the 6 × 9 in, 200-page example that is 3,811 × 2,775 pixels for the whole wrap. KDP accepts PDF files up to 650 MB and recommends keeping covers under 40 MB.

Where does the barcode go on a KDP cover?

In the lower-right corner of the back cover. If you don't add your own, KDP prints one in a 2 × 1.2 in white box, so keep that area free of text and important art.

Is a hardcover cover bigger than a paperback cover?

Yes. The hardcover cover wraps around boards: it adds a 15 mm wrap on every edge, the boards are 5 mm wider and 6 mm taller than the trim, and the spine gets 4.8 mm more. The same 6 × 9 in, 200-page book needs a 14.214 × 10.417 in hardcover cover.

Can I use this template in Canva?

Yes, with the PNG. Create a custom-size design at the full cover size first (12.7 × 9.25 in for the 6 × 9 in, 200-page example), upload the 300 DPI PNG and place it as the bottom layer, design over it, then hide or delete it and export a PDF. In Illustrator, Affinity or Inkscape, use the SVG: its guides are separate layers.

Is this the same as KDP's cover calculator?

It uses the same formula: bleed + back cover + spine + front cover + bleed, with the spine from the page count and the paper. The spine factors are checked against KDP's cover calculator. One difference to know: this page always uses the even page count KDP prints, while KDP's calculator takes the number as typed, so an odd count gives a spine one page thinner there. KDP's calculator also gives a downloadable template, worth a final check before you upload.

What size is a Kindle eBook cover?

Kindle covers are a separate JPEG, not a wrap: KDP's ideal size is 1,600 × 2,560 pixels (a 1.6:1 height-to-width ratio).
