How to Format a KDP Hardcover: 9 Steps That Actually Work

Before opening KDP or any design tool, have these four things ready or you will waste time backtracking.

Final manuscript as a PDF or DOCX. KDP accepts both, but PDF gives you exact control over fonts, spacing, and layout. If your interior has images, tables, or custom fonts, always export as PDF/X-1a.

Final page count confirmed. Your spine width depends on this number, and your cover cannot be built until you know it. Hardcovers on KDP require a minimum of 75 pages and a maximum of 550 pages. Count your pages in the final formatted file, not in your word processor's draft view.

Trim size decided. KDP supports the following hardcover trim sizes as of 2025: 5×8, 5.06×7.81, 5.25×8, 5.5×8.5, 6×9, and 8.5×11 inches. The 6×9 is the most widely used for nonfiction and fiction. Specialty sizes like 8.5×11 work for workbooks and activity books.

A design tool ready. You will need either KDP's free Cover Creator (limited but functional), Adobe InDesign, Affinity Publisher, or Canva with the correct artboard dimensions. For cover work specifically, see our comparison of KDP cover design tools to pick the right one for your workflow.

Log into your KDP account at kdp.amazon.com. From the Bookshelf, click + Create and select Paperback or Hardcover. Do not select Kindle — hardcover is a print product only.

Fill in your title, subtitle, author name, series information (if applicable), and description on the first screen. Under Publication date, leave this blank unless you are setting a specific release date. Under ISBN, KDP will assign a free ISBN for hardcover — you can also enter your own if you purchased one from Bowker or another provider.

Scroll to Print options. Select Hardcover from the binding dropdown. You will then see two sub-options: Case laminate (a printed image wraps the hardboard cover) and Image wrap (no dust jacket, image printed directly on the board). Case laminate is the standard choice for most genres. Image wrap has a slightly different cover template, so confirm your binding choice before building your cover file.

Common mistake: Switching binding type after you have already built your cover. The cover template dimensions differ between case laminate and image wrap, so a cover built for one will not upload correctly for the other.

Still on the Print Options screen, set your Trim size from the dropdown. Enter the exact trim size you decided in Prerequisites. If your size is not in the dropdown, KDP does not support it for hardcover — you cannot use a custom size.

Set Interior ink to either Black & white or Premium color. Premium color increases your printing cost significantly, which compresses your royalty margin. For a 6×9 hardcover at 200 pages, black and white printing costs approximately $6.39 to print, while premium color costs approximately $12.99 to print (as of KDP's published pricing tables, 2025). Check the current numbers in your KDP dashboard under the Royalty Calculator tab before committing.

Set Paper type to white or cream. This matters for spine width calculation in Step 4. White paper is 0.002252 inches per page, cream is 0.0025 inches per page.

Common mistake: Choosing premium color for a book that only has black and white charts or simple graphics. The royalty hit is substantial. Only use premium color if your interior genuinely requires full-color images throughout.

Your interior PDF must match the trim size exactly. Set your document size in your design tool to the exact trim dimensions — for a 6×9 book, your page size is 6×9 inches, not letter size.

Set margins to a minimum of 0.25 inches on all sides. For the gutter (the inside margin that gets bound), KDP recommends a minimum of 0.375 inches for books under 300 pages and 0.5 inches for books over 300 pages. Going narrower than this causes text to disappear into the spine after binding.

If your interior has full-bleed images or backgrounds that extend to the page edge, add 0.125 inches of bleed on all sides. This means your document size becomes 6.25×9.25 inches for a 6×9 trim. All live content (text, logos, critical images) must stay at least 0.25 inches inside the trim line.

Embed all fonts in your PDF export. In Adobe InDesign, this is under Export > Adobe PDF > Advanced > Fonts. In Affinity Publisher, check the PDF export settings under Compatibility. Missing fonts are the number one reason KDP rejects interior files.

Common mistake: Building your interior at letter size (8.5×11) and expecting KDP to scale it down. KDP does not scale interiors. Your file must be exactly the trim size, or it will be rejected or print incorrectly. See our full guide on creating interior pages for KDP for a deeper walkthrough of margin and bleed setup.

This is the step most authors skip and then wonder why their cover upload fails. You cannot guess at spine width.

Use this formula:
- White paper: Page count × 0.002252 inches
- Cream paper: Page count × 0.0025 inches

For a 200-page book on white paper: 200 × 0.002252 = 0.4504 inches of spine width.

Once you have your spine width, go back to the KDP manuscript upload page and click Download Cover Template. Enter your trim size, page count, and paper type into the template generator. KDP will produce a PDF template with exact dimensions for your front cover, back cover, spine, and bleed areas marked out. Download this template and use it as your cover design foundation — do not build a cover from scratch without it.

For case laminate hardcovers, the template includes a wraparound area for the boards. For image wrap, the template includes fold-over dimensions. These are different files, so confirm your binding type before downloading.

Common mistake: Using a paperback cover template for a hardcover. The dimensions are different. Always download a fresh template from the hardcover listing, not from a previous paperback project.

Open the KDP cover template in your design tool. The template shows you the safe zones, bleed areas, and fold lines as colored guides. Design within these guides — do not place text or critical images in the bleed zone or near the spine fold lines.

For the spine, keep text at least 0.0625 inches away from both edges of the spine. If your spine width is under 0.25 inches, KDP will not allow spine text at all — it simply does not have enough room to print legibly. For most 6×9 hardcovers, you need at least 100 pages on white paper to get a usable spine width of 0.225 inches.

Cover resolution must be 300 DPI minimum. RGB color mode is acceptable for KDP's print system (unlike some offset printers), but if you are aiming for color accuracy, CMYK is safer. Export your final cover as a single-page PDF with bleed included.

For case laminate covers, the image wraps around the physical board edges. Your template will show the fold areas — keep these zones free of critical design elements because they will be folded and glued, not visible on the finished product.

Common mistake: Placing the author name or title text too close to the spine on the front cover. After binding and trimming, content within 0.125 inches of the trim edge may be cut off. See our guide to KDP cover design mistakes for a full list of layout errors that cause rejections and poor print quality.

On the KDP manuscript upload page, click Upload manuscript and select your interior PDF. KDP will process the file, which takes between 2 and 10 minutes depending on file size. While it processes, do not navigate away from the page.

Once processing completes, KDP will show you a Launch Previewer button. Click it. The online previewer shows you a page-by-page rendering of your interior. Check the following in the previewer: margins are consistent, no text is cut off at the edges, images are rendering at the correct resolution, and page numbers are appearing correctly.

The previewer is not pixel-perfect for print, but it will catch major layout errors. If KDP flags warnings (yellow) versus errors (red), yellow warnings do not prevent publishing but may indicate quality issues. Red errors must be resolved before you can proceed.

Common mistake: Uploading a DOCX file with embedded images and assuming the formatting will hold. DOCX files are converted by KDP's system, and the conversion often shifts margins, changes font rendering, and reflows text. For any book with precise layout, always upload a PDF.

On the same page, below the manuscript upload section, click Upload cover and select your cover PDF. KDP processes cover files faster than interiors, typically under 2 minutes.

After processing, KDP will show a cover preview. Check that the spine text is centered within the spine area, the front cover image is not cropped unexpectedly, and the back cover content (if any) is within the safe zone. If you see the cover preview showing a white border where your bleed should be, your cover PDF was exported without bleed — go back to your design tool and re-export with bleed marks included.

KDP also runs an automated quality check on the cover. Common flags include: image resolution below 300 DPI, cover dimensions that do not match the template, and font issues if you submitted a rasterized cover without embedding vectors. If your cover is rejected at this stage, the error message will specify which issue triggered the rejection.

Common mistake: Submitting a cover with a transparent background instead of a white or filled background. KDP's system does not handle transparency in cover PDFs well, and it often renders as a black or gray background in the final print.

Click Save and Continue to reach the Rights and Pricing page. Under Territory rights, select Worldwide unless you have specific territorial restrictions from a prior publishing agreement.

Under Primary marketplace, set your primary market (typically Amazon.com for US-based authors). Then set your list price. KDP will calculate your royalty in real time as you type the price. Hardcover royalties on KDP are calculated as 60% of the list price, minus the printing cost.

Using the example from Step 2: a 200-page, 6×9 B&W hardcover with a printing cost of $6.39, priced at $19.99, earns: (0.60 × $19.99) − $6.39 = $11.99 − $6.39 = $5.60 per unit sold. KDP will show you this calculation directly on the pricing page — use it to test different price points before locking in.

KDP hardcovers are not eligible for Expanded Distribution as of 2025. Your hardcover will sell on Amazon's marketplaces only. If you want bookstore or library distribution for your hardcover, you need a separate ISBN and a distributor like IngramSpark.

Common mistake: Pricing your hardcover below the minimum price KDP requires to cover printing costs. KDP will not allow you to publish at a price that results in a negative royalty. The minimum price is calculated dynamically based on your page count and trim size.

Click Publish Your Hardcover Book. KDP will submit your book for review. Hardcover review times are typically 24–72 hours, longer than ebook reviews, because KDP's print team manually checks print files in addition to the automated review.

You can monitor status from your KDP Bookshelf. The status will move through: In Review, then either Live or Action Required. If it goes to Action Required, KDP will send an email specifying the issue. Common reasons include: interior file has transparency or font errors, cover dimensions do not match the interior page count, or the title on the cover does not match the title entered in the listing metadata.

Once live, order a physical proof copy before running any promotions. Go to your Bookshelf, click the three-dot menu on your hardcover title, and select Order author copies. Proof copies are sold at printing cost with no royalty markup. Inspect the proof for spine alignment, color accuracy, and binding quality before directing buyers to the listing.

Common mistake: Skipping the proof copy and going straight to promotion. Print-on-demand hardcovers occasionally have binding variance between print runs. Catching a defect before you have 50 customer orders is worth the $8–$15 proof cost.

Issue 1: Cover upload rejected with 'dimensions do not match'
This almost always means you downloaded the cover template before finalizing your page count, then changed your page count during interior formatting. Even a one-page difference changes the spine width calculation. Re-download the cover template with the correct final page count, rebuild the spine area of your cover, and re-export.

Issue 2: Interior flagged for 'low resolution images'
KDP requires 300 DPI at the final print size. An image that is 300 DPI at 2×2 inches becomes 150 DPI when placed at 4×4 inches. Check each image in your interior at its actual placed size, not its source resolution. In InDesign, use Window > Links to see the effective PPI of each placed image.

Issue 3: Spine text is off-center in the printed proof
This is a print variance issue, not necessarily a design error. KDP's print-on-demand system has a spine alignment tolerance of approximately ±0.0625 inches. If your spine text appears slightly off in one proof copy, order a second proof before concluding it is a design problem. If it is consistently off-center across two proofs, adjust your spine text position in your design file by the measured offset amount.

Issue 4: Book shows as 'In Review' for more than 72 hours
This occasionally happens during high-volume periods (Q4, January). Wait up to 96 hours before contacting KDP support. If it exceeds 96 hours, use the KDP Contact Us form and select Print Book as the product type. Include your ASIN and the date of submission in your message — this speeds up the support response significantly.
