KDP Coloring Book Requirements (2026): Bleed, Margins, DPI and Blank Pages

Nov 5, 2026 · Rey Midas · From KDP’s help pages, read that day

A coloring book interior doesn’t need bleed if the line art stays inside KDP’s margins. Each image needs at least 300 DPI at the size it prints, the book needs at least 24 pages, and blank backs are fine as long as no more than 4 blank pages sit in a row before the last printed page (KDP allows 10 at the end). Embed every font in the PDF and flatten transparency. The rules are below, each with a link to the KDP help page it comes from.

Disclosure: we sell a coloring book generator, the Coloring Book Machine ($9.99). Near the end we measure its files against these rules, including one it failed until November 5, 2026.

KDP’s interior rules for a coloring book

Rule	KDP’s number	Source
Bleed	Optional. If used: 0.125″ is cut from the top, bottom and outside edges, so each page is trim width + 0.125″ and trim height + 0.25″. One bleed page means the whole file uses bleed.	Trim, bleed and margins
Inside (gutter) margin	0.375″ for 24–150 pages; 0.5″ for 151–300	Trim, bleed and margins
Outside margin	At least 0.25″ without bleed, 0.375″ with bleed	Trim, bleed and margins
Image resolution	At least 300 DPI. Under 200 DPI is “low resolution.” Up to 600 DPI recommended to stay under the file limit.	Submission guidelines
Page count	Minimum 24, rounded up to an even number. 8.5 × 11″ black ink: up to 590 pages on white, 550 on cream.	Trim, bleed and margins
Blank pages	No more than 4 in a row at the beginning or middle; 10 in a row at the end	Fix formatting issues
Fonts	All fonts embedded	Submission guidelines
Transparency	Flattened	Submission guidelines
File	PDF (required for bleed); 650 MB maximum	Submission guidelines
Trim sizes	8.5 × 11″, 8.5 × 8.5″ and 8 × 10″ are all listed (as large trims)	Trim, bleed and margins
Paper (black ink)	Cream, white or groundwood. No coloring-book recommendation.	Paper and ink
Printing cost	Black ink, large trim, Amazon.com: $2.84 for 24–110 pages	Printing cost
ISBN and AI	Coloring books are “Not Generally Low-Content,” so they need an ISBN (free from KDP). Disclose AI-generated content.	Low-content books

All links go to kdp.amazon.com help pages, read November 5, 2026. Printing cost is for books sold on Amazon.com. KDP counts a trim as large when it is wider than 6.12″ or taller than 9″, so 8.5 × 11″ and 8.5 × 8.5″ are priced the same.

Bleed or no bleed

KDP trims every page by cutting 0.125″ from the top, bottom and outside edges. Bleed means your ink runs past that cut so nothing white shows at the edge. A bleed page is 0.125″ wider and 0.25″ taller than the trim: 8.625 × 11.25″ for an 8.5 × 11″ book.

Most coloring pages are line art on a white page, and the drawing doesn’t touch the edge. Those need no bleed, and no bleed is simpler: the page is exactly the trim size and you only have to respect the margins. Bleed has one catch: KDP says “even if just one page in your interior requires bleed, then your entire file should be set up with bleed,” and a bleed book must be uploaded as a PDF. Bleed doesn’t change the price: KDP says bleed settings and cover finish don’t affect printing cost.

Margins, by page count

Margins are the minimum white space between your art and the edge. The inside (gutter) margin, on the spine side, grows with page count. KDP’s table: 0.375″ for 24–150 pages, 0.5″ for 151–300, 0.625″ for 301–500, 0.75″ for 501–700 and 0.875″ for 701–828. The outside margins (top, bottom and outer edge) must be at least 0.25″ without bleed and 0.375″ with bleed. A 102-page coloring book falls in the first band, so keep every drawing at least 0.375″ from the spine edge and 0.25″ from the others.

DPI is pixels at printed size

KDP’s submission guidelines say “all images (both cover and manuscript) should be at least 300 DPI.” DPI is not a property of the image alone. It is the image’s pixels divided by the inches it covers on paper. A design 2048 pixels wide printed 6.8 inches wide is 2048 ÷ 6.8 ≈ 301 DPI. Stretch the same image across the full 8.5-inch page and it drops to 2048 ÷ 8.5 ≈ 241 DPI. To fill 6.8 inches at 300 DPI you need 6.8 × 300 = 2,040 pixels.

The DPI tag saved inside an image file (the “72” or “300” you see in an image editor) is just a label. Changing it adds no pixels, so it isn’t what matters. What counts is the pixels and the size the image prints at.

KDP defines low resolution as “any image containing less than 200 DPI.” Its pages don’t say whether an image between 200 and 300 DPI, or under 200, gets a warning or a rejection. At the top end, KDP recommends no more than 600 DPI to keep the file under its 650 MB limit.

Page count and blank backs

KDP’s minimum is 24 pages, rounded up to an even number. The maximum for an 8.5 × 11″ black-ink book is 590 pages on white paper and 550 on cream. For 8 × 10″ and 6 × 9″ it is 828.

The blank-page limit is in KDP’s formatting help: “no more than 4 consecutive blank pages at the beginning or middle of a manuscript file” and no more than 10 consecutive blank pages at the end. KDP’s submission guidelines also list excessive blank pages as a common reason a file fails.

KDP has no rule that names blank backs. None of its help pages mention single-sided coloring pages, to require them or forbid them. Printing each design with a blank back puts one blank page between designs, which is under the 4-in-a-row limit. A 50-design book with blank backs works out like this:

Title page and its blank back: 2 pages
50 designs, each with a blank back: 50 × 2 = 100 pages
Total: 102 pages. Even, above 24, and never more than 1 blank page in a row.

A short book needs care at the end. Ten designs with backs plus a title spread is 22 pages, so you pad to 24 and the book ends with 3 blank pages in a row. That is under the end limit of 10. For how many pages coloring books on Amazon actually run, see our page count of top Amazon coloring books.

Fonts, transparency and file size

A coloring book has few words, but the title page and any page labels use fonts. KDP’s submission guidelines say “all fonts in the interior files should be embedded” and transparency should be flattened (the formatting help says the same). The interior must be a PDF if it uses bleed, and the file can be up to 650 MB.

White or cream paper

KDP’s paper and ink page says black ink books can be printed on “cream, white, or groundwood paper.” KDP makes no recommendation for coloring books specifically, and we haven’t tested one paper against the other. The only difference its tables show for an 8.5 × 11″ book is the page limit: 590 on white, 550 on cream.

Printing cost and royalty

KDP charges a fixed fee plus a per-page fee. For a black-ink, large-trim book sold on Amazon.com it is a flat $2.84 from 24 to 110 pages, and above that $1.00 plus $0.017 a page. Regular trims cost $2.30 for 24–110 pages. A 102-page 8.5 × 11″ book costs $2.84 to print. At a $9.99 list price and KDP’s 60% royalty, you earn 0.6 × $9.99 − $2.84 = $3.15 a sale (royalty at every price). Premium color is a different scale: $1.00 plus $0.08 a page above 40 pages, which for 102 pages is $9.16, more than the $5.99 royalty share of a $9.99 book.

AI disclosure and the ISBN

If AI drew your pages, KDP’s content guidelines ask you to disclose it when you publish. Many guides call coloring books “low-content,” but KDP’s low-content page lists them as “Not Generally Low-Content.” Low-content books are the ones KDP lets you publish without an ISBN, so a coloring book paperback needs one like any other paperback. KDP gives you one free. More on both in KDP’s AI rules, quoted.

How our Machine’s files measure against this

We sell the Coloring Book Machine for $9.99, so here is how its interior PDF measures against the rules above, checked in the code and on a live file on November 5, 2026:

Trim and bleed: 8.5 × 11″ or 8.5 × 8.5″, no bleed.
Resolution: each design is 2048 pixels square, printed 6.8″ wide: about 301 DPI.
Margins: designs sit 0.85″ from the left and right edges on both trims (title text at least 0.75″); 2.1″ top and bottom on 8.5 × 11″, 0.85″ on 8.5 × 8.5″. All above the 0.375″ gutter and 0.25″ outside minimums.
Pages: a title page and blank back, then each design with a blank back, padded to an even count of at least 24. 10 designs make 24 pages, 50 make 102. The longest blank run is 3, at the end of a 10-design book; everywhere else it is 1.
File size: the 50-design, 102-page PDF we tested was 14.9 MB.
Fonts: until November 5, 2026 the title page used standard PDF fonts that were not embedded, which breaks KDP’s embedded-fonts rule. Since that day the title page uses an embedded font (Noto Sans), and a font check on a live file shows it embedded.

You still look the pages over before you upload, and you answer yes to KDP’s AI question.

Questions

Do KDP coloring books need bleed?

No. Bleed is only needed when ink runs to the edge of the trimmed page. Line art kept inside KDP’s margins (at least 0.375″ on the inside and 0.25″ on the outside for a 24–150-page book) prints without bleed. If even one page bleeds, KDP says the whole file should be set up with bleed: every page 0.125″ wider and 0.25″ taller than the trim, uploaded as a PDF.

What DPI should coloring pages be for KDP?

At least 300 DPI, measured at the size the image prints: pixels divided by printed inches. A 2048-pixel design printed 6.8 inches wide is about 301 DPI. KDP calls any image under 200 DPI low resolution and recommends going no higher than 600 DPI to keep the file under its 650 MB limit. The DPI number saved in an image file doesn’t add pixels; only the pixels and the printed size matter.

Can a KDP coloring book have blank pages?

Yes, within limits. KDP’s formatting help allows no more than 4 consecutive blank pages at the beginning or middle of the file and 10 at the end, and lists excessive blank pages as a common reason files fail review. A blank back behind each design is one blank page in a row.

Should coloring pages be single-sided?

KDP doesn’t say. None of its help pages mention blank backs in coloring books, to require or forbid them. It is your choice: one design per sheet means marker that soaks through lands on a blank page instead of another design. It doubles the page count (50 designs plus a title page is 102 pages), and an 8.5 × 11″ black-ink book of 102 pages still costs $2.84 to print.

What is the minimum page count for a KDP coloring book?

24 pages, and the count must be even. Blank backs count, so a title page, its back and 11 designs with blank backs make exactly 24. An 8.5 × 11″ black-ink book can run to 590 pages on white paper and 550 on cream.

What paper should I choose for a KDP coloring book?

KDP says black ink books can be printed on cream, white or groundwood paper, and it makes no recommendation for coloring books. The one difference its tables show for an 8.5 × 11″ book is the page limit: 590 pages on white, 550 on cream.

Does a KDP coloring book need an ISBN?

Yes. Low-content books are the ones KDP lets you publish without an ISBN, and KDP lists coloring books as “Not Generally Low-Content,” so a coloring book paperback needs one. KDP offers a free ISBN. If AI drew the pages, KDP’s content guidelines ask you to disclose that at upload.
