IngramSpark for distribution. KDPEasy for the cover.
Same print-ready file, both platforms. IngramSpark gets you into bookstores and libraries. KDP runs the Amazon machine. KDPEasy generates the one cover that uploads to both, with the spine width recalculated for each printer automatically.
This is not an either/or decision
Most serious self-publishers use IngramSpark and KDP. They are different jobs. KDP runs Amazon (the search engine, the reviews, the Kindle ecosystem). IngramSpark runs everything else (bookstores, libraries, international wholesale, dust-jacket hardcovers). The two platforms barely overlap.
The one piece that sits upstream of both is the cover. You need a print-ready full-wrap PDF for each platform, and the spine width is different on each because the paper stocks are different. That is the gap KDPEasy fills. Generate one cover, export two files, upload to two platforms.
KDP vs IngramSpark for printing and distribution
Two print-on-demand platforms with different sales channels. Both are owned by large players (Amazon and Ingram Content Group). Both are legitimate. They serve different distribution intent.
| Dimension | Amazon KDP | IngramSpark |
|---|---|---|
| Reach | Amazon + KDP expanded distribution (limited bookstores) | 40,000+ retailers, bookstores, libraries, global wholesale |
| Returnability | Not returnable (a non-starter for most bookstores) | Optional returnability (required by most physical bookstores) |
| Setup fees | $0 to publish, ever | $0 for paperback now (2026); ~$25 per cover/interior correction |
| Royalty model | 60% on Amazon list price minus print cost | List price minus trade discount (you pick 30-55%) minus print cost |
| Payment cadence | ~60 days after end of sale month | ~90 days after end of sale month |
| Hardcover quality | Case laminate only; limited trim sizes | Case laminate + dust jacket, more trims, paper choices |
| Speed to live | 24 to 72 hours on Amazon | 2 to 4 weeks to retailer feeds |
| Cover upload requirements Same bleed; spine width formula differs by paper stock | Single full-wrap PDF (front + spine + back, bleed 0.125") | Single full-wrap PDF (front + spine + back, bleed 0.125") |
The cover comes from somewhere. Where?
Neither IngramSpark nor KDP designs your cover. They both expect a finished print-ready PDF. These are your three options for getting one.
| Dimension | KDPEasy | Freelance designer | Canva / template |
|---|---|---|---|
| Time per cover | ~2 minutes | 5 to 14 days | 30 to 90 minutes |
| Cost per cover | From $2 (subscription) or $3.50 PAYG | $150 to $800+ | $10 to $40 + your time |
| Print-ready for KDP | Yes, automatic | Usually | Sometimes (you tweak) |
| Print-ready for IngramSpark | Yes, dimensions exported for IS template | Charge usually applies | You re-export manually |
| Spine width math | Auto from page count + paper | Designer handles it | You enter manually |
| Revisions | Unlimited regenerations | 2 to 3 rounds typical | Self-serve |
Should you use IngramSpark, KDP, or both?
Four concrete book types and the platform choice that actually makes sense for each.
Debut novel
Get the Amazon listing live in 72 hours, build reviews, then add IngramSpark when you want library and indie bookstore coverage. KDPEasy generates one cover that works for both uploads.
Low-content puzzle book
Bookstores rarely stock low-content. The Amazon long tail is the entire business model. IngramSpark setup work is overhead that does not pay back here.
Illustrated children's book
Independent bookstores and libraries are the real revenue. IngramSpark gives you returnability and proper trim sizes. KDP catches the Amazon search traffic. Use KDPEasy to generate the wrap, then re-export at IngramSpark spine dimensions.
Business hardcover
IngramSpark's hardcover quality (dust jacket option, cloth, more trims) is the right product for a $25 to $35 list price. Run the paperback through KDP for the Amazon machine. Two covers, two trims, both from KDPEasy.
Where IngramSpark and KDP covers differ
The artwork is identical. The math at the spine is not. Here is what actually changes.
Same: bleed
0.125 inches (3.175mm) on all sides. Both platforms accept the identical bleed allowance, so your artwork extends past the trim by the same amount.
Different: spine width
IngramSpark uses 50 lb or 70 lb paper depending on book type. KDP uses its own white or cream stock. For a 300-page book, the spine width can differ by 1 to 3 millimeters between platforms.
Different: trim availability
IngramSpark offers more trim sizes than KDP (especially for hardcovers and large-format books). KDP covers most common sizes (5x8, 6x9, 8.5x11) but fewer specialty trims.
How KDPEasy handles the spec difference
Pick your platform (KDP, IngramSpark, or both), enter page count and trim size, and KDPEasy outputs the wrap at the right total dimensions. For "both" you get two files: a KDP-spec wrap and an IngramSpark-spec wrap from the same generated artwork. No re-design, no re-export tools, no manual spine math.
IngramSpark vs KDP: real per-book costs
Standard 6x9 paperback, 250 pages B&W. Royalties shown after print cost. IngramSpark trade discount set at 40% (the common default for wide distribution).
| Cost item | Amazon KDP | IngramSpark |
|---|---|---|
| Setup fee | $0 | $0 (paperback, 2026) |
| Correction fee | $0 | ~$25 per cover or interior file |
| Print cost (250pg B&W, 6x9) | ~$3.65 | ~$4.85 |
| Print cost (color, 100pg) | ~$5.20 (premium) | ~$6.40 |
| Cover creation (with KDPEasy) | $2 to $3.50 | $2 to $3.50 (same file) |
| Royalty on a $14.99 paperback (Amazon) | ~$5.35 | ~$3.10 (40% discount setting) |
| Royalty on a $14.99 paperback (B&N) | ~$2.95 (expanded) | ~$3.90 |
The smart play most pros run
- Generate the cover in KDPEasy. Export both files (KDP spec + IngramSpark spec).
- Publish on KDP first. Enroll in KDP Select for 90 days to get Kindle Unlimited and Countdown Deals.
- After 90 days, opt out of Select. Now add IngramSpark for wide paperback distribution. Keep the KDP listing for Amazon.
- Set your IngramSpark trade discount to 40% and turn on returnability if you want bookstore stocking.
- For hardcovers, run them through IngramSpark from day one. Dust jacket option, better trim selection, premium price absorbs the higher print cost.
One cover, two upload-ready files
The piece both IngramSpark and KDP require but neither provides: a print-ready full-wrap PDF with the spine width calculated for that specific printer.
2-minute generation
Enter your title, page count, trim size, and pick a style. AI generates the full-wrap composition: front, spine, back, all dimensions correct.
Dual-platform export
Pick KDP, IngramSpark, or both. KDPEasy exports the wrap at each platform's spine width and total dimensions from the same artwork.
Bleed and DPI baked in
0.125" bleed, 300 DPI, CMYK output. Print-ready by default, no second pass to fix specs after generation.
No correction fees
IngramSpark charges roughly $25 per uploaded correction. Get the cover right the first time. KDPEasy regenerations are free.
Hardcover-aware
Generate covers for KDP case laminate or IngramSpark dust jacket / cloth-bound hardcover. Different spine and flap math, handled automatically.
Use both platforms confidently
The biggest barrier to going wide with IngramSpark is the cover work. KDPEasy removes that friction so you can run the smart KDP + IngramSpark stack.
