Print on demand coloring books · Amazon KDP paperback
Print on demand coloring books — what one costs to print, and what you keep
A 300-page 6 × 9 black-and-white paperback costs $4.60 to print on Amazon.com: $1.00 fixed plus $0.012 a page. Up to 110 pages it is flat at $2.30, so a 48-page coloring book prints for the same money as a 110-page one. At $12.99 a copy you keep $3.19.
The book builder opens later — not today
The costs and file checks below are live and are the same ones the calculators use. The part that draws the pages is still being built, so there is nothing here to generate a book with yet.
Print on demand means you never buy stock: KDP prints one copy when one copy sells, and takes the printing cost out of the sale before paying you the royalty. That makes two numbers matter more than anything else in the listing — what the interior costs to print, and how far the price can move before the royalty rate drops.

Flat up to 110 pages: the bar only starts growing when the per-page charge begins.
The cost table
Seven page counts, one rate card, no guessing
Everything below is computed from the same table the free calculator uses: a fixed cost per book plus a per-page cost, with a flat tier that ignores page count up to 110 pages. The 300-page row is the one most paperback listings land near.
| Pages | Tier | Fixed | Per page | Print cost | Lowest price | Royalty at $12.99 |
|---|---|---|---|---|---|---|
| 24 | Flat | $2.30 | — | $2.30 | $4.60 | $5.49 |
| 48 | Flat | $2.30 | — | $2.30 | $4.60 | $5.49 |
| 66 | Flat | $2.30 | — | $2.30 | $4.60 | $5.49 |
| 100 | Flat | $2.30 | — | $2.30 | $4.60 | $5.49 |
| 110 | Flat | $2.30 | — | $2.30 | $4.60 | $5.49 |
| 111 | Per page | $1.00 | $0.012 | $2.33 | $4.66 | $5.46 |
| 120 | Per page | $1.00 | $0.012 | $2.44 | $4.88 | $5.35 |
| 300 | Per page | $1.00 | $0.012 | $4.60 | $9.20 | $3.19 |
Two rows in that table are worth staring at. Pages 100 and 110 cost exactly the same as 24 — the flat tier doing its job, with no reward for cutting pages. Page 111 is the first page that is charged at all, and from there the cost climbs by $0.012 a page.
Printing cost = fixed + (pages × per-page). Flat tier ends at 110 pages for black ink · rates checked 2026-11-10
Two files, four steps
The interior and the cover wrap — and nothing else
KDP asks for two files. The interior is the book; the wrap is the cover, the back and the spine in one wide sheet whose width comes from the page count. Get the second one wrong and the book is rejected before anyone sees the inside.
- 01
Export the interior PDF
One page per sheet at 6 × 9in trim, 6.125 × 9.25in with bleed, 300 DPI artwork and a gutter that grows with the page count.
- 02
Build the cover wrap
Back cover, spine and front cover in one file. At 300 pages on white paper the spine is 0.6756in and the whole wrap is 12.9256 × 9.25in.
- 03
Upload both files and fix the price
KDP shows the printing cost for your page count while you set the list price, so you can see the royalty before you publish rather than after.
- 04
Order a proof before you tell anyone
A printed copy is the only way to check line weight, paper show-through and whether the gutter swallows the middle of a design.
The wrap is where seasonal books break. A cover built for last year’s page count has the wrong spine, so the title drifts toward one edge and the back cover blurb slides under the trim. Rebuild the wrap whenever the page count changes — it takes a minute and saves a week of review.
Work out your own
Change the page count and watch the three numbers move
The slider drives the printing cost, the lowest price that still pays you, and the royalty at whatever price you set. Defaults are the 300-page example used across this page.

Two things move in opposite directions. More pages cost more to print but allow a higher listing price, and the royalty rate itself steps down to 50% below $9.98 — so the lowest viable price is usually the 60%-tier floor, not the arithmetic minimum.
Five niches with a buyer
Where a coloring book has room
A generic coloring book competes with everything. These five have a buyer who searches for the thing itself, and each one is a line-art workload the maker covers.
Winter and snow
Snowmen, mittens, sleds — the December peak, plus a snow-day edition in January.
Cozy interiors
Cabins, fireplaces, mugs. Quiet, detailed pages for adult books and gel pens.
Space and planets
One big closed star is the easy version; orbits and rings carry the detail pages.
Birthdays and parties
Boxes, bows and cakes, sold year round and never out of season.
Patterns and mandalas
Round, symmetrical shapes that suit the finest line weights in the maker.
Your own niche
One sentence in the maker is enough to start a set on a theme nobody has covered.
How the line art is made
All five are the same size of job — the page count, the print cost and the cover wrap barely move between them. What changes is the listing: a niche buyer searches for the theme rather than for “coloring book”, which makes the title and the seven keyword fields easier to fill with words people actually type.
Questions
Print-on-demand questions
For a 6 × 9 black-and-white paperback in the US it is $1.00 plus $0.012 a page, which is $4.60 at 300 pages. Up to 110 pages the cost is flat at $2.30, so a 48-page book and a 110-page book print for the same money.
At $12.99 you are on the 60% tier: 60% of $12.99 is $7.79, minus $4.60 of printing, which leaves $3.19 a copy. Below $9.98 the rate drops to 50%, which is why the lowest viable price here is $9.20 and not the arithmetic minimum.
An interior PDF and a cover wrap. The interior is every page at trim with 0.125in bleed on the outer edges and a gutter that grows with the page count; the wrap is one wide file holding back cover, spine and front cover, sized from the page count.
Because the spine is the paper. White stock adds 0.002252in per page, so 300 pages is 0.6756in and 600 pages is 1.3512in. Change the page count after the cover is built and the spine no longer matches, which is the most common reason a cover file is rejected.
You can, but 8.5 × 11 is what buyers expect and what gives a child room to colour. A large trim moves the interior onto KDP’s large-trim rate — same page count, higher cost — so check the print cost before you fix the list price.
KDP gives you a free ISBN for the paperback and adds the barcode to the back cover for you. Leave the barcode area clear of artwork and text: a design printed under the barcode is a rejection waiting to happen, and it costs a week to fix.
