Lulu vs IngramSpark vs Amazon KDP: An Honest Comparison for Self-Publishing Authors

If you've spent any time researching how to self-publish your book, you've probably hit the same wall most authors do: there are three big platforms — Lulu, IngramSpark, and Amazon KDP — and every comparison article seems to end with "it depends." Which is true, but unhelpful when you're trying to pick one.

This guide is different. We'll lay out exactly what each platform does well, what it does poorly, and which type of author each one actually serves best. By the end, you'll know which one (or which combination) makes sense for your book — without needing to test all three.

A quick note about us: we run RexPress, a book printing service for self-publishing authors. We use Lulu as our printing supplier, so we know that platform from the inside. We've also helped authors who came to us after frustrating experiences on KDP and IngramSpark, so we know those platforms' rough edges too. We're not affiliated with any of them, and we'll be honest about all three — including when one of them is the right answer instead of us.

The Short Answer: Which Platform Should You Use?

If you only read one section, read this one:

Use Amazon KDP if you want the simplest possible setup, you're primarily targeting Amazon readers, and you don't care much about bookstore distribution. KDP is free, fast, and Amazon's ecosystem reaches the most readers.

Use IngramSpark if you want your book in physical bookstores, libraries, and non-Amazon retailers. Their distribution network reaches over 40,000 retailers globally — a level of reach KDP can't match.

Use Lulu if you want the highest print quality, unusual formats (hardcover with dust jacket, photo books, spiral binding, custom sizes), or if you sell books primarily through your own website or at events.

Use a combination if you want both Amazon's reach AND wider bookstore distribution — many successful indie authors use KDP for Amazon and IngramSpark for everywhere else.

These three platforms all share one thing in common: they're DIY. You upload files, you handle proofing, you troubleshoot issues, you manage the relationship. That works well for some authors and badly for others. If you'd rather not manage any of this yourself, there's a different category of service worth knowing about — we'll cover that toward the end of this post.

Amazon KDP: The Default Choice for Amazon-First Authors

Amazon Kindle Direct Publishing (KDP) is the easiest way to get a book listed on Amazon. It's free, the interface is straightforward, and the platform reaches more readers than any other single channel.

What KDP does well

It's genuinely free. No setup fees, no revision fees, no monthly costs. You upload your files, set your price, and go. KDP recoups its costs by deducting printing expenses from your royalty when a book sells.

It's fast. Books typically go live on Amazon within 24-72 hours of approval. If you need to make changes after publication, those go live in roughly the same window — and there's no fee for revisions, ever.

Amazon's reach is unmatched. Amazon controls roughly 70-80% of the U.S. ebook market and a large share of online print sales. If your book isn't on Amazon, most readers will never find it.

Customer service has improved. Live chat support has replaced the old email-only system, and most authors report quick responses now.

Where KDP falls short

Bookstore distribution is essentially nonexistent. Amazon offers "Expanded Distribution" to non-Amazon retailers, but most independent bookstores refuse to stock KDP-printed books because they don't want to send revenue to their largest competitor. If physical bookstore placement matters to you, KDP alone won't get you there.

The free ISBN is a long-term limitation. KDP's free ISBN lists "Independently published" or Amazon as the publisher. That's fine for most readers, but it can hurt you if you ever want bookstore distribution, library acquisition, or professional credibility. Authors who care about this buy their own ISBN through Bowker for $125.

Print quality is acceptable, not excellent. KDP's paper and binding are functional but slightly thinner and less premium than Lulu or IngramSpark. Most readers won't notice; design-conscious authors will.

Hardcover options are limited. KDP added hardcover printing in 2021, but the format choices are narrower than competitors and the quality is mid-tier.

Best fit for KDP

First-time authors publishing a novel or non-fiction book where Amazon will be the primary sales channel. If you don't have ambitions for bookstore distribution and you want the lowest-friction path to a published book, KDP is hard to beat.

IngramSpark: The Bookstore and Library Path

IngramSpark is the self-publishing arm of Ingram Content Group — the world's largest book distributor. Their core value proposition is distribution: through IngramSpark, your book becomes orderable by over 40,000 retailers, libraries, and online stores worldwide.

What IngramSpark does well

Real bookstore and library distribution. This is the big one. IngramSpark feeds the same wholesale catalog that Barnes & Noble, independent bookstores, and libraries use to order books. Being in this catalog doesn't guarantee placement, but it makes ordering possible — which is the necessary first step for any physical bookstore presence.

Professional file standards. IngramSpark's file requirements are more demanding than KDP's. The upside: books that pass IngramSpark's checks tend to look more professionally produced.

Hardcover and binding options. IngramSpark offers more binding choices than KDP, including casebound hardcover with dust jacket — the format readers expect from traditionally published books.

Setup fees are gone (for now). IngramSpark eliminated setup fees for new titles in 2023, and revisions within 60 days of publication are free. This was a major change that made the platform much more affordable to test.

Where IngramSpark falls short

Revision fees after 60 days hurt. Once your 60-day window closes, every file change costs $25. If you're the type of author who tweaks covers or fixes typos over time, this adds up. Authors who prefer KDP's unlimited free revisions often stay there for that reason alone.

The market access fee just went up. As of February 2026, IngramSpark charges a 1.875% fee on every distributed sale (up from 1.5%). This is small per book but cumulative across your catalog and sales volume.

The interface has a learning curve. IngramSpark assumes you know what you're doing. File specs, wholesale discount math, distribution settings — if you're new to publishing, expect to spend time figuring it out. KDP, by comparison, holds your hand.

Customer service is email-only. No live chat, no phone support. Response times are reasonable but not fast.

The "global distribution" reality is more nuanced than it sounds. Being listed in Ingram's catalog means retailers can order your book — not that they will. Most indie authors who set up IngramSpark distribution don't see their books actually appear on bookstore shelves unless they actively promote to those bookstores.

Best fit for IngramSpark

Authors who want bookstore and library access, who have well-prepped files, and who are willing to invest the time to learn the platform. Often used in combination with KDP — KDP for Amazon, IngramSpark for everything else.

Lulu: The Print Quality and Flexibility Specialist

Lulu has been in print-on-demand longer than most competitors — since 2002. Their core strengths are print quality and format variety. If you have a book that doesn't fit neatly into KDP or IngramSpark's standard formats, Lulu can probably print it.

What Lulu does well

Print quality is genuinely excellent. Lulu's premium color printing and paper stock options exceed what you'll find on KDP or IngramSpark. For children's books, photo books, art books, and any project where print quality is part of the product, Lulu is the strongest of the three.

Format flexibility is unmatched. Hardcover with dust jacket, casewrap hardcover, photo books, comic books, calendars, spiral binding, custom trim sizes — Lulu prints formats the other two simply don't offer.

Free to publish. No setup fees. Free ISBN if you want one (or use your own).

Direct-to-reader sales via API. Lulu offers an integration that lets authors sell printed books directly from their own websites with Lulu handling printing and fulfillment. This is genuinely useful for authors with established audiences who'd rather sell direct than route everything through Amazon.

Author copies pricing is competitive. For authors who sell at events or directly to readers, Lulu's per-copy pricing is often the best of the three platforms.

Where Lulu falls short

Distribution is the weakest link. Lulu offers global retail distribution, but it routes through Ingram — meaning if you want bookstore reach, you're paying Lulu's cut on top of Ingram's. Most authors who want serious distribution use IngramSpark directly.

Royalty math through Lulu's distribution can be ugly. When you sell through Lulu's expanded retail channels, the combination of platform fees, distributor fees, and retailer discounts can leave you earning very little per copy. Authors who use Lulu well usually use it for direct sales, not retail distribution.

The platform isn't as polished as KDP. Lulu's interface is functional but feels less modern. The publishing flow has more friction than KDP's near-frictionless setup.

Customer service can be slow. Email-based support with multi-day response times is common. If something goes wrong mid-print-run, you may wait.

Best fit for Lulu

Authors with visual or specialty books (children's, photography, art, cookbooks), authors selling primarily through their own website or at events, or authors who need format options the other platforms don't offer.

How the Three Platforms Stack Up

You've seen each platform individually. Now the question is: how do they compare directly? Here's the honest breakdown across the four dimensions that matter most.

Pricing

All three platforms are technically free to publish, but the fee structures differ in ways that catch people off guard.

KDP is the cleanest: zero setup, zero revision fees, zero monthly costs. You only pay printing costs, and those come out of your royalty when a book sells. For authors who plan to update their book over time, this is a real advantage.

IngramSpark is also free to set up, with 60 days of free revisions after upload. After that 60-day window, every file change costs $25. The 1.875% market access fee on distributed sales (as of February 2026) is small per copy but adds up over time.

Lulu is free to publish with no setup or revision fees. Per-copy printing costs for author copies are competitive — often the cheapest of the three for direct purchases. Where Lulu gets expensive is on retail distribution, where the layered fees can leave you with very little royalty.

Per-copy print costs are roughly comparable across all three for standard paperbacks at standard trim sizes. The differences are real but small — typically within 10-15% of each other for the same book. Where the gaps widen is on hardcover, color interiors, and unusual formats, where Lulu often comes out ahead on quality and IngramSpark often ahead on cost.

Practical takeaway: If you're price-sensitive and plan to revise your book often, KDP wins. If you want bookstore distribution and your files are final, IngramSpark works. If quality and format options matter, Lulu's per-copy economics are competitive for direct sales.

Distribution Reach

This is the dimension where the platforms actually differ the most.

KDP dominates Amazon — which is a huge channel — but its reach off Amazon is minimal. KDP's "Expanded Distribution" technically makes your book orderable elsewhere, but the practical reality is that few non-Amazon retailers stock KDP books. If you publish only through KDP, your book is essentially an Amazon-only product.

IngramSpark offers genuine wholesale distribution. Their catalog is the same one that bookstores, libraries, and chain retailers actually use to order books. This doesn't guarantee placement — independent bookstores still need a reason to stock you — but it makes ordering possible, which is the prerequisite for any physical retail presence.

Lulu offers global retail distribution that routes through Ingram. The reach is similar to IngramSpark's on paper, but the royalty math after Lulu's cut is usually less favorable. Most authors who want retail distribution use IngramSpark directly rather than Lulu's distribution layer.

Practical takeaway: For Amazon-first authors, KDP is enough. For authors who want bookstores and libraries, you'll want IngramSpark, either alone or alongside KDP. Lulu's distribution is useful only in specific situations — most authors using Lulu use it for direct sales, not retail.

Print Quality and Format Options

This is where Lulu pulls ahead, especially for visual books.

Lulu has the strongest print quality of the three, particularly for color interiors, premium paper stocks, and specialty bindings. They also offer the widest range of formats — hardcover with dust jacket, photo books, spiral-bound workbooks, comic book formats, custom trim sizes. If your book has any unusual requirements, Lulu can probably handle them.

IngramSpark is solidly mid-tier on print quality with respectable hardcover options including casebound editions with dust jackets. The paper and binding are professional-grade, suitable for retail.

KDP is acceptable for standard paperbacks but the weakest of the three for premium formats. Hardcover printing is available but the quality and options trail Lulu noticeably.

Practical takeaway: For straightforward novels and non-fiction, all three are fine. For children's books, photo books, art books, cookbooks, or anything where the physical product is part of the experience, Lulu is the clear choice. For traditional hardcover non-fiction or literary fiction with a dust jacket, IngramSpark is solid.

Ease of Use and Support

If you've never published a book before, this matters more than you'd think.

KDP is the easiest to use. The interface walks you through every step. File requirements are forgiving. Revisions are free and fast. Customer support has live chat. For first-time authors, the friction is genuinely minimal.

Lulu sits in the middle. The interface is functional but less polished than KDP. The publishing flow has more steps. Support is helpful but slower (email-based, multi-day response times are common).

IngramSpark is the most demanding. The platform assumes you understand publishing concepts like wholesale discounts, file specifications, and distribution settings. Email-only support means you wait days for answers when you're stuck. The learning curve is real and is the main reason many authors stay on KDP even when IngramSpark would serve them better.

Practical takeaway: First-time authors usually do best starting with KDP, then adding IngramSpark later once they've learned the basics. Trying to learn IngramSpark as your first publishing experience is often frustrating.

Common Author Profiles: Which Platform Fits You?

Generic comparisons only get you so far. Here's how the choice typically breaks down by author type.

The First-Time Novelist

You've written a novel. You want it on Amazon. You're not sure about bookstores. You don't have endless time to learn publishing platforms.

Recommendation: Start with KDP only. Get the book live, learn the basics, see how it sells. If demand justifies it later, add IngramSpark for wider distribution. Most first-time novelists never need anything more than KDP for years.

The Bookstore-Focused Author

You want your book in physical bookstores. You're willing to do the legwork — emailing local stores, attending events, building relationships with indie bookshops.

Recommendation: KDP for Amazon plus IngramSpark for everywhere else. Buy your own ISBN through Bowker so you're listed as the publisher rather than Amazon. This is the standard "wide" indie author setup.

The Children's Book or Photography Author

Your book lives or dies on print quality. Color reproduction matters. The physical product is the experience.

Recommendation: Lulu for direct sales and quality-sensitive distribution. Consider adding KDP for Amazon visibility, but make sure to order proofs from KDP first to confirm the quality is acceptable for your specific book — color reproduction can vary noticeably.

The Event-Driven Author

You sell most copies at speaking engagements, workshops, conferences, or directly through your website. Amazon and bookstores are secondary.

Recommendation: Lulu for author copies (best per-copy economics for direct sales) plus their direct-sales API if you sell from your own site. KDP optional for the discoverability bump on Amazon.

The Cookbook, Workbook, or Reference Author

Your book needs to lay flat. Spiral binding or coil binding is essential to the user experience.

Recommendation: Lulu, almost without exception. KDP and IngramSpark don't offer the binding options you need.

The Established Author Selling at Real Volume

You've been publishing for a while. You're moving thousands of copies per year — maybe tens of thousands — across multiple titles.

Recommendation: None of these three platforms are optimal anymore. At real volume, the print-on-demand model becomes expensive compared to short-run digital or offset printing. Most established authors at this stage start working with print brokers who can negotiate better per-copy costs across multiple suppliers. We'll cover this more in the next section.

A Fourth Option Worth Knowing About

Everything we've covered so far assumes you'll manage one of these platforms yourself — uploading files, troubleshooting issues, handling proofs, dealing with customer service when things go wrong.

For many authors, that's fine. Self-service is what these platforms are built for, and they work well when your files are clean, your project is straightforward, and you have time to learn.

But there's a category of author who's not well-served by DIY:

Authors whose files aren't print-ready. If your book exists as a Word doc with images dropped in, none of these platforms will produce a professional result without significant prep work. The platforms will accept the file and print something — but the spine width will be wrong, the images will be low resolution, the bleeds will be missing, and you won't know until you have a stack of unsellable books in your garage.

Authors who don't have time to learn. Self-publishing has a real learning curve. If you're a busy professional, a parent, someone with a day job, or simply someone who'd rather spend your hours writing than figuring out CMYK color profiles, the time cost of DIY is significant.

Authors with a launch deadline. If you have a book launch event, a speaking engagement, or a holiday season target, you can't afford to learn IngramSpark's quirks the hard way.

Established authors at volume. As mentioned above, once you're moving thousands of copies per year, the per-copy economics of POD start to look expensive compared to industrial digital or offset printing. A print broker can usually save you meaningful money — sometimes thousands per year, sometimes much more.

This is where a service like RexPress fits in. We work as a layer between authors and printers (Lulu for short runs, industrial partners for high-volume work). Authors send us their files, we handle the prep, the proofing, the printer communication, and the print-run management. The trade-off is straightforward: roughly a 35% premium over DIY pricing on short runs (in exchange for done-for-you service), or significant savings on volume (in exchange for moving away from POD).

We're not the right fit for everyone. If you're print-savvy, your files are clean, and you enjoy the technical side, DIY platforms will save you money. We're a fit for the authors who'd rather hand it off.

Your Next Steps

The right next step depends on where you are with your book. Here's how to put everything you've just read into action.

If You're Just Starting Out

Don't pick a platform yet. Finish your manuscript first, get it edited, and decide on your trim size and binding. Platform choice matters less than file quality — a great book on KDP outsells a poorly prepped book on IngramSpark every time.

When your manuscript is final and you have a cover you actually love, then it's time to pick a platform. For most first-time authors, that platform should be KDP — it's the lowest-friction way to get your first book published. You can always add IngramSpark or Lulu later.

If You're Comparison-Shopping for Your First Book

Read this post once, then make a decision and move on. Authors who spend three months agonizing over Lulu vs IngramSpark vs KDP usually publish later, sell less, and learn nothing useful in the process.

Pick the platform that fits your goals — KDP for Amazon-first, IngramSpark for bookstores, Lulu for visual books — and start there. The platform decision is reversible. The decision to actually publish is the one that compounds.

If Your Files Aren't Print-Ready

This is the moment to get a free file review before you commit to any platform. None of these three services will fix your files for you — they'll print whatever you upload. If your interior images are 72 DPI, your spine width is wrong, or your bleeds are missing, you'll discover it when your printed proofs arrive in the mail.

Submit your files for a free review at RexPress and we'll tell you in plain English what's print-ready, what needs attention, and what it'll take to fix anything that's off. No quote required, no obligation.

If You'd Rather Have Someone Handle the Whole Thing

If managing platforms, troubleshooting file issues, and chasing customer service isn't how you want to spend your time, that's a legitimate reason to use a service-based provider instead of going DIY.

Request a quote at RexPress and we'll respond within one business day with detailed pricing for your specific project. We handle file prep, proofing, printer communication, and the entire print run — you focus on writing and selling your book.

If You're Selling at Real Volume Already

If you're moving thousands of copies per year through any combination of these platforms, you're almost certainly overpaying. POD economics work for early-stage authors but become expensive at volume — print brokers using industrial digital or offset printing can typically save established authors 30-50% on per-copy costs.

Tell us about your project — we'll give you a real number to compare against your current per-copy costs. Most established authors at volume are surprised by how much they could be saving.

The Bottom Line

Lulu, IngramSpark, and Amazon KDP are all legitimate platforms. None of them is universally "best" — they serve different authors with different goals. The honest answer to "which should I use" almost always depends on whether you want Amazon reach, bookstore distribution, or premium print quality.

For most first-time authors, the right path is simpler than the comparison articles make it sound: start with KDP, learn the basics, and add other platforms later if your goals require them.

For authors who'd rather not manage any of this, a service-based provider exists for exactly that reason. Either way, the goal is the same — getting your book printed and into readers' hands without losing months to platform research or thousands to avoidable mistakes.
