Print on Demand Amazon: A–Z Glossary & Guide (2026)

TL;DR: Print on demand on Amazon lets you sell physical books without inventory, upfront costs, or minimum print runs. Amazon’s KDP platform prints each copy after a customer orders it and pays you a royalty (60% or 50%, depending on your list price) minus the printing cost. This glossary covers every term you’ll encounter, from bleed and trim size to the June 2025 royalty change that most guides still haven’t updated for.

How Print on Demand Works on Amazon

Print on demand (POD) is a manufacturing model where each book copy is printed only after someone buys it. There’s no warehouse full of boxes. No minimum order of 500 copies. No upfront investment in inventory that might never sell.

Amazon’s print on demand service lives inside Kindle Direct Publishing (KDP), which handles ebooks, paperbacks, and hardcovers under one roof. The platform is free to use. There’s no account fee, no upload fee, and no per-title charge. Amazon makes its money by taking a percentage of each sale instead.

The basic flow works like this: you upload your interior PDF and cover file, set your list price, and publish. When a customer clicks “Buy,” one of Amazon’s POD printing plants produces your book, ships it, and deposits your royalty. KDP’s printing facilities now operate in multiple countries, so a buyer in Germany gets a copy printed locally rather than shipped from the United States.

If you’re brand new to the platform, our step-by-step KDP publishing guide walks through the entire process from account setup to your first sale.

A quick note on history: Amazon used to run its POD service through a separate platform called CreateSpace. In 2018, CreateSpace merged into KDP, and all print on demand functionality now lives there. Hardcover printing was added in 2021.

The A–Z Glossary of Print on Demand Amazon Terms

A

ASIN (Amazon Standard Identification Number)
Amazon’s unique 10-character product identifier. Every book published through KDP gets one automatically. Your ASIN is not your ISBN; it’s Amazon-specific and used for internal cataloging, search, and advertising.

Author Copies
Physical copies you order at printing cost only, with no royalty charged. Authors typically buy these for events, signings, gifts, or personal inventory. They’re different from proof copies (see below) because author copies are available after your book goes live.

B

Back Matter
Everything that comes after your main text: author bio, also-by page, glossary, index, acknowledgments. Strong back matter drives series sell-through and newsletter signups. For tips on writing the author bio portion, see this guide on how to write an about-the-author page.

Barcode
The machine-readable representation of your ISBN, printed on the back cover so retailers can scan it. KDP generates one automatically if you use their free ISBN. If you supply your own ISBN from Bowker, you’ll need to generate a matching barcode.

Bleed
The 0.125 inches of extra image area that extends past the trim line on every side. After printing, the pages are cut at the trim line, and the bleed area ensures ink reaches the very edge with no white border. Text-only book interiors don’t need bleed. Full-page images, colored backgrounds, and design elements that touch the page edge do. One detail worth noting: bleed settings do not change your printing cost.

Book Block
The trimmed, collated interior pages before binding. Think of it as the guts of your book, everything between the covers, stacked and cut to final dimensions.

C

Case Laminate
KDP’s hardcover binding method. The cover boards are wrapped in a printed, laminated sheet. KDP does not offer dust jackets, so case laminate is your only hardcover option on the platform.

CMYK (Cyan, Magenta, Yellow, Key/Black)
The color model used for print files. KDP requires PDF uploads in CMYK. If you upload RGB files (the color model used for screens), KDP will auto-convert them, and the results often look duller than expected. Always convert to CMYK before uploading.

Cover File
A separate PDF that includes the front cover, spine, and back cover as a single wraparound image. The dimensions must match KDP’s template exactly, which varies based on your page count, trim size, and paper type. KDP provides a downloadable template calculator. For more on cover specs, our book cover design glossary breaks down every requirement.

CreateSpace
Amazon’s former print on demand platform, which operated independently until 2018. All CreateSpace titles were migrated to KDP. You’ll still see CreateSpace mentioned in older guides, forums, and YouTube tutorials, but the platform no longer exists.

D

DPI (Dots Per Inch)
Print resolution measurement. KDP requires a minimum of 300 DPI for both interior and cover files. Images below 300 DPI will look blurry or pixelated in print, even if they looked fine on screen.

E

Expanded Distribution
KDP’s opt-in channel that makes your paperback available to non-Amazon retailers (bookstores, libraries, online retailers) through part of Ingram’s distribution network. The royalty rate drops to 40% (compared to 60% for direct Amazon sales at $9.99 and above). Only paperbacks are eligible.

Here’s the critical warning that practitioners on Reddit repeat constantly: if you tick Expanded Distribution on KDP, Amazon claims your ISBN in Ingram’s system. This blocks you from listing the same title on IngramSpark with that ISBN. If you plan to use IngramSpark for bookstore and library distribution (and most serious indie authors do), leave Expanded Distribution unchecked on KDP.

F

Fixed Cost
The base printing charge per copy before per-page costs are added. For a regular-trim black-ink paperback with more than 110 pages, the fixed cost is $1.00. For hardcovers, the fixed cost runs about $4.65 higher than the equivalent paperback.

Front Matter
Everything before your main text begins: half-title page, title page, copyright page, dedication, table of contents, foreword, preface. Front matter pages count toward your total page count and therefore affect printing cost.

G

Glossy Finish
One of two cover coating options (the other is matte). Glossy covers have a shiny, reflective surface. The choice between glossy and matte is purely aesthetic because both cost the same to print.

Groundwood Paper
A slightly cheaper paper option available only for black-and-white paperbacks. It’s roughly 5% cheaper per page than standard white paper. The savings amount to pennies per copy, but for high-volume sellers those pennies add up over thousands of units.

Gutter
The inner margin area near the spine, between facing pages. If your gutter is too narrow, text will disappear into the binding and readers will have to crack the spine to read it. Thicker books need wider gutters. KDP’s guidelines specify minimum gutter widths based on page count.

H

Hardcover
KDP added hardcover print on demand in 2021. Hardcovers require a minimum of 75 pages, use case laminate binding (no dust jackets), and carry a higher fixed printing cost. For a detailed comparison of formats, costs, and royalties, check out this hardback vs. paperback breakdown.

I

Interior File
The PDF containing all of your book’s pages. It must match your chosen trim size exactly. KDP accepts PDF files only for print interiors (not Word documents, though you can use KDP’s built-in tool to convert a .docx).

ISBN (International Standard Book Number)
A 13-digit number that uniquely identifies one edition of one book in one format. A paperback, hardcover, and ebook each need their own ISBN. KDP offers a free ISBN, but it can only be used on Amazon. If you want to sell across multiple platforms, you’ll need to purchase your own through Bowker. Our ISBN guide for self-publishers explains the tradeoffs.

K

KDP (Kindle Direct Publishing)
Amazon’s self-publishing platform. It handles ebooks, paperbacks, and hardcovers. KDP is where all print on demand Amazon activity happens, from file upload through royalty payments.

KDP Select
An optional ebook exclusivity program that enrolls your book in Kindle Unlimited (KU). This is an ebook-only feature and does not affect your print on demand editions. You can publish print books on KDP while distributing ebooks through other platforms, but if you enroll in KDP Select, your ebook must be exclusive to Amazon.

KENP (Kindle Edition Normalized Pages)
The unit Amazon uses to measure Kindle Unlimited reads. Authors in KDP Select earn from the KU fund based on KENP read. This is irrelevant to print on demand but comes up constantly in KDP dashboards, so it’s worth knowing what it means.

L

Large Trim
Any trim size wider than 6.12 inches or taller than 9 inches. Large trim books use a higher per-page printing rate. This classification catches authors off guard because a seemingly small dimension change (say, from 6×9 to 6.14×9.21) bumps you into the more expensive tier.

List Price
The retail price you set for your book. It determines two things: your royalty tier (50% or 60% for paperbacks, as of the June 2025 change) and whether you meet KDP’s minimum list price requirement.

M

Matte Finish
The alternative to glossy cover coating. Matte has a smooth, non-reflective surface that many authors prefer for literary fiction and nonfiction. Same printing cost as glossy.

Metadata
The information that helps readers find your book: title, subtitle, description, keywords, and categories. Metadata is the single biggest lever for discoverability on Amazon. Getting it right is a marketing decision as much as a publishing one. If you want help with the promotional side, book marketing services can optimize your metadata alongside ad campaigns.

Minimum List Price
The lowest price KDP allows you to set. It must be high enough to cover the printing cost divided by the royalty rate so that Amazon doesn’t lose money on every sale. KDP calculates this automatically, but understanding the formula helps you plan pricing before you publish.

P

PDF (Print-Ready)
The file format KDP requires for both interior and cover uploads. Your PDF should be flattened (no layers), embedded fonts, CMYK color, and 300 DPI minimum resolution.

Perfect Binding
The standard paperback binding method where interior pages are glued to the spine of the cover. This is KDP’s default (and only) binding option for paperbacks. It’s the same binding you see on most mass-market and trade paperbacks in bookstores.

Premium Color
The highest quality color printing KDP offers. At $0.065 per page for regular trim (or $0.080 for large trim), it’s expensive for long books. A 200-page premium color book costs $14.00 just to print ($1.00 fixed + 200 × $0.065). This option makes sense for photo books, art books, and children’s picture books where color fidelity is critical.

Print Previewer
KDP’s built-in tool that shows an approximation of how your book will look in print. It catches obvious problems like text running into gutters or images extending past the safe zone, but it’s not a substitute for ordering a physical proof.

Printing Cost
The amount Amazon deducts from your royalty per sale. The formula is: fixed cost + (page count × per-page rate). This number varies by ink type, paper type, trim size, and marketplace.

POD (Print on Demand)
The manufacturing model itself. Each copy is printed only after purchase, eliminating inventory risk. Print on demand on Amazon specifically means KDP handles manufacturing, shipping, and customer service while you handle the content and pricing.

Proof Copy
A physical review copy you order before publishing your book. It ships from KDP at printing cost (plus shipping) and arrives with a “Not for Resale” banner. Always order a proof. Practitioners on self-publishing forums consistently say this is non-negotiable. One author on Reddit shared that they found upside-down pages and crooked cuts in KDP print runs, issues they would have caught with a proof before going live.

R

Regular Trim
Any trim size 6.12 inches wide or under and 9 inches tall or under. The most common self-publishing trim, 6×9 inches, falls into this category and uses the lower per-page printing rates.

Returnability
Whether booksellers can return unsold copies to the distributor for a refund. KDP print on demand books are non-returnable. This is the single biggest reason brick-and-mortar bookstores won’t stock them. Bookstores operate on thin margins and depend on the ability to return slow-selling titles. If getting into physical bookstores matters to you, IngramSpark (with returns enabled) is the better channel.

Royalty Rate
The percentage of your list price that Amazon pays you after deducting the printing cost. As of June 2025, Amazon introduced a tiered system for paperbacks and hardcovers: 60% for books priced at $9.99 and above, 50% for books priced at $9.98 and below. Expanded Distribution pays a flat 40%. Most competing guides still reference a flat 60% rate because they haven’t updated for this change.

The formula: (List Price × Royalty Rate) minus Printing Cost = Your Royalty.

S

Safe Zone
The area inside the trim line and gutter margins where all text and important design elements must stay. Anything outside the safe zone risks being cut off during trimming or swallowed by the binding.

Spine Width
The thickness of your book’s spine, determined by page count and paper type. Your cover file must account for the exact spine width, or the cover art will shift and look off-center. KDP’s cover template calculator gives you the precise measurement. For design rules and formulas, see this guide on spine design for print books.

Standard Color
KDP’s mid-tier color printing option at $0.0255 per page for regular trim. It’s roughly 2.5 times the cost of black ink per page but only about 39% the cost of premium color. A workbook with occasional charts or a cookbook with a few color photos can be commercially viable in standard color, while a photography book probably needs premium.

T

Trim Size
The finished width × height of your printed pages. The 6×9 inch trim is the most popular for self-published fiction and nonfiction because it’s a standard trade paperback size, falls within the “regular trim” pricing tier, and looks professional on a shelf. KDP supports trim sizes from 5×8 inches up to 8.5×11 inches.

W

Wide Distribution
The strategy of using KDP for Amazon sales and IngramSpark for bookstores, libraries, and other retailers. This is the consensus best practice among experienced indie authors. KDP wins on Amazon because it earns the Buy Box on its own platform. IngramSpark wins everywhere else because it offers returnability, customizable wholesale discounts, and access to over 40,000 retail and library partners. For a deeper comparison, read our overview of print on demand services across all major platforms.

Wholesale Discount
The percentage off the list price that retailers pay when ordering your book. On IngramSpark, you set this yourself (typically 55% for bookstore distribution). On KDP, the wholesale discount is fixed by Amazon and baked into the royalty structure. You don’t control it directly.

Quick-Reference Printing Cost Table (2026, US Marketplace)

These figures apply to regular-trim paperbacks (6×9 inches or smaller). All costs are per copy.

Page Count	Black Ink	Standard Color	Premium Color
100	$2.30 (flat)	$3.55	$7.50
200	$3.40	$6.10	$14.00
300	$4.60	$8.65	$20.50
400	$5.80	$11.20	$27.00
500	$7.00	$13.75	$33.50

Worked example for a 300-page black-ink paperback: $1.00 fixed cost + (300 pages × $0.012 per page) = $4.60 printing cost. If you price the book at $14.99, your royalty is ($14.99 × 0.60) minus $4.60 = $4.39 per sale.

Common Print on Demand Mistakes to Avoid

1. Enabling Expanded Distribution when you plan to use IngramSpark.
This is the number one mistake discussed in r/selfpublish threads. Ticking that box locks your ISBN into Amazon’s slice of Ingram’s network, blocks you from listing on IngramSpark with the same ISBN, and cuts your Amazon royalty from 60% to 40% on those expanded sales. If you want bookstore and library reach, handle it through IngramSpark directly.

2. Pricing below $9.99 without realizing the royalty drop.
Since June 2025, paperbacks and hardcovers priced under $9.99 earn only 50% instead of 60%. That 10-percentage-point difference is significant. A $9.98 book earns a 50% rate while a $9.99 book earns 60%. For most books, the one-cent price increase is worth it.

3. Uploading RGB files instead of CMYK.
Your monitor displays colors in RGB. Printers use CMYK. The conversion is lossy, meaning bright blues and vivid greens often turn muddy. Convert your files to CMYK in your design software before uploading, and compare a soft proof against your original.

4. Forgetting to widen the gutter on thick books.
A 100-page novel needs less gutter space than a 400-page epic. If you use the same margins for both, the thicker book will have text that vanishes into the spine. KDP publishes minimum gutter recommendations by page count, and you should follow them.

5. Skipping the proof copy.
Practitioners on forums and YouTube walkthroughs share horror stories about misprints, color shifts, and formatting issues they didn’t catch until readers complained. A proof copy costs you the printing price plus shipping. It’s the cheapest insurance in publishing. An experienced practitioner noted in an Adobe Community thread that KDP print plants vary in age, equipment, and press management, creating variations most authors never realize exist.

6. Ignoring the large trim cost jump.
Moving from a 6×9 trim to, say, a 6.14×9.21 pushes you into the large trim pricing column with higher per-page rates. Check KDP’s trim size classifications before finalizing your interior layout.

POD Amazon vs. Going Wide: A Decision Framework

KDP print on demand is unbeatable for Amazon sales. Your books appear directly in the Amazon catalog, benefit from Prime shipping, and earn the highest royalty rate the platform offers. But KDP alone won’t get you into bookstores or libraries. Its Expanded Distribution option is limited to the US and UK, carries a lower royalty, and produces non-returnable books that brick-and-mortar stores won’t stock.

IngramSpark fills that gap. It reaches over 40,000 retailers and library systems worldwide, lets you enable returns, and gives you control over your wholesale discount. The tradeoff is a $49-per-title setup fee and slightly different print specs.

The consensus among experienced indie authors is clear: use both. KDP handles Amazon. IngramSpark handles everywhere else. Just make sure you use a different ISBN for each platform (or use the free KDP ISBN for Amazon and a Bowker ISBN for IngramSpark). And never tick Expanded Distribution on KDP if you’re going this route.

Authors who want maximum reach should also consider audio. The audiobook market continues to grow, and adding that format puts your title in front of listeners on Audible, Spotify, Apple Books, and dozens of other platforms. Audiobook production services can handle narrator casting, recording, and distribution if you’d rather not manage it yourself.

Frequently Asked Questions

Is print on demand on Amazon really free?

Yes. KDP charges no account fees, no upload fees, and no per-title fees. Amazon earns its revenue by taking a percentage of each sale (the inverse of your royalty rate) and deducting the printing cost. You pay nothing until a book sells.

What is the royalty rate for print on demand Amazon books?

As of June 2025, paperback and hardcover royalties are 60% of the list price for books priced at $9.99 and above, and 50% for books priced at $9.98 and below. Expanded Distribution sales earn 40% regardless of price. Your royalty is calculated as (list price × royalty rate) minus printing cost.

How much does it cost to print a book through Amazon KDP?

It depends on page count, ink type, and trim size. A 300-page black-ink regular-trim paperback costs $4.60 to print ($1.00 fixed + $0.012 per page). Color books cost significantly more, with premium color running $0.065 per page for regular trim.

Can I sell print on demand Amazon books in bookstores?

Not effectively. KDP books are non-returnable, and most brick-and-mortar bookstores won’t order stock they can’t return if it doesn’t sell. If bookstore placement is important to you, publish through IngramSpark with returns enabled and a 55% wholesale discount.

What’s the difference between KDP Expanded Distribution and IngramSpark?

KDP’s Expanded Distribution uses part of Ingram’s network but only reaches the US and UK, pays a 40% royalty, and offers no returnability. IngramSpark provides global distribution to 40,000+ retailers and libraries, lets you enable returns, and gives you control over your wholesale discount. Most indie authors skip Expanded Distribution entirely and use IngramSpark for non-Amazon channels.

Does the cover finish affect the printing cost on Amazon KDP?

No. Glossy and matte finishes cost exactly the same. Choose based on your book’s genre and aesthetic, not budget.

What trim size should I use for print on demand on Amazon?

The 6×9 inch trim is the most popular for self-published fiction and nonfiction. It falls within the “regular trim” pricing tier (lower per-page rates), fits standard bookshelf dimensions, and is the expected size for trade paperbacks. Only go larger if your content requires it, and be aware that any trim wider than 6.12 inches or taller than 9 inches triggers higher printing costs.

Should I use Amazon’s free ISBN or buy my own?

KDP’s free ISBN can only be used on Amazon. If you plan to distribute through IngramSpark or other platforms, buy your own ISBN through Bowker so you control it across all channels. Our ISBN pricing guide breaks down costs and bulk discounts.
