KDP cover size calculator, made simple.

Enter your trim size, final formatted page count, interior type, and paper type. The calculator adds the back cover, spine, front cover, and 0.125 inches of bleed on both outer edges. For example, a 6 × 9 inch, 100-page paperback on white paper has a 0.2252-inch spine and a 12.4752 × 9.25 inch full cover.

For black-and-white books, spine width is page count × 0.002252 inches on white paper or page count × 0.0025 inches on cream paper. Groundwood uses 0.00235 inches per page, and color uses 0.002347 inches per page. Amazon's current paperback guidance does not add a separate 0.06-inch cover allowance.

The pixel size depends on trim size, page count, paper type, and spine width. Multiply the final dimensions in inches by 300 DPI. For example, a 6 × 9 inch, 200-page paperback on white paper needs a 3810 × 2775 pixel canvas after rounding.

Amazon recommends an eBook cover that is 2,560 pixels high by 1,600 pixels wide, an ideal height-to-width ratio of 1.6:1. The minimum is 1,000 by 625 pixels.

eBook covers are digital, so pixels and aspect ratio matter more than physical inches. At Amazon's specified 72 DPI metadata, 1,600 × 2,560 pixels corresponds to about 22.22 × 35.56 inches, but you should design to the pixel dimensions rather than that print size.

KDP requires 0.125 inches, or about 3.2 millimeters, of bleed on every outside edge of a paperback cover. Keep important content at least 0.25 inches from the outside cover edge.

Popular trim sizes include 6 × 9 inches for non-fiction, 5 × 8 inches for novels, 5.5 × 8.5 inches for digest books, and 8.5 × 11 inches for workbooks and large-print books. The calculator includes Amazon's common presets plus custom trim dimensions.

Yes. Most supported paperback configurations start at 24 pages, while standard color starts at 72 pages. Large-print books can use presets such as 6 × 9, 7 × 10, or 8.5 × 11 inches, subject to Amazon's page limits for the selected interior and paper.

This browser-based calculator applies the formulas automatically, validates the selected page range, converts inches to millimeters and pixels, and creates SVG and PNG guide templates. No spreadsheet or account is required.

Not yet. This tool currently supports KDP paperbacks and Kindle eBooks. Hardcover covers require additional hinge, board, and wrap measurements, so use Amazon's official cover calculator for hardcover templates.

Build and export paperback cover artwork at 300 DPI using the pixel dimensions shown by the calculator. Kindle eBook covers should use Amazon's recommended 1600 × 2560 pixel dimensions and RGB color profile.

This tool uses the paperback formulas published in Amazon's submission guidelines and adds a faster live preview, pixel conversion, and local SVG and PNG downloads. Always verify a final upload with Amazon's official previewer because available print configurations can change.

Use the final interior page count and the intended trim size, often 8.5 × 11 or 8.5 × 8.5 inches. Low-content books use the same paperback formula, but permitted page ranges depend on trim, interior, and paper selections.

Amazon prints spine text only on books with more than 79 pages. Keep spine text at least 0.0625 inches from each side of the spine and allow for normal binding variation.

Yes. Download the PNG for Canva or the SVG for vector-capable design software. Use it as a guide layer, remove or hide it before export, and verify the finished cover in KDP's official previewer.

No. The calculations are for KDP perfect-bound paperbacks. Amazon KDP does not currently offer standard coil-bound or spiral-bound printing.

Multiply each dimension in inches by 300. A 12.75 × 9.25 inch cover becomes 3825 × 2775 pixels at 300 DPI. The calculator performs this conversion and rounds to the nearest whole pixel.

Total width = (trim width × 2) + spine width + (bleed × 2). Total height = trim height + (bleed × 2). With a 6 × 9 trim and 0.5-inch spine, the full cover is 12.75 × 9.25 inches.

It is a size calculator and template generator rather than an artwork converter. Use the calculated canvas and downloaded guide to resize or rebuild an existing cover in Canva, Photoshop, Affinity, or Illustrator.
