What minimums and pricing do KDP, IngramSpark, Lulu, and BookVault state?
Checked 17 October 2026. KDP's print-options page says: "As a manufacture-on-demand company, we produce units as they're ordered, which reduces excess production." A minimum number of copies is not stated on that page. Per-copy print prices for a given page count are on the printing-cost pages linked below, not restated here. IngramSpark's book-printing page says: "IngramSpark prints your book as soon as it's ordered, and can't be out of stock." It also says: "With our bulk print pricing, you can save more by printing more." A minimum quantity, a lead time, and a per-copy price are not stated on that marketing page. Use the calculator it points to, or the rate card already quoted on the print-on-demand cost page. Lulu's basics article, modified Fri, Jun 12, 2026, says: "At Lulu, there is no minimum (or maximum) order." It also says bulk discounts begin at 100 copies. Creating a book and offering it in the Lulu bookstore does not cost anything. Costs start when you purchase. When a customer buys, Lulu takes "20% of the profit for printed books and 10% for ebooks." Profit is the purchase price minus the base price for materials and printing. A per-copy print price is not stated. The page points to a calculator. A proof copy must be purchased and approved before a print book can qualify for retail distribution. Lulu says it is not a publisher. BookVault's minimum-quantity page says you can order "as little as one copy," and: "There is no minimum order quantity for standard Bookvault print-on-demand orders." Larger orders "may qualify for bulk pricing or volume discounts depending on the quantity and book specification." The copy count for that discount is not stated on the page. It says some BookvaultBespoke products may have different minimums and tells you to check the product article or quote tool. A dollar price is not stated. BookVault's production-time page gives estimates, and it says they are not guaranteed and may be longer at peak. For orders placed on the BookVault platform, Standard is an estimated 5 to 7 working days, with a 3pm UK cut-off. Express is aimed at 3 working days, with a 7am cut-off. Priority is aimed at the same day or the next working day, with a 7am cut-off, and casebound books cannot use Priority. Bespoke orders aim at 15 working days. Paperback books from the US, Canada, and Australia partners are an estimated 3 to 5 working days, and hardback books 5 to 7. Those times are for printing and dispatch. Delivery depends on the shipping service. A dollar price is not stated.[439][440][441][443][444]
- None of these four pages states a copy count where offset is the cheaper choice.
- Author-copy and wholesale formulas for KDP and IngramSpark are on the print-cost answer, with the examples those pages publish.
02
What does one offset printer state about minimums, time, and price?
PrintNinja's hardcover page, checked 17 October 2026, says: "Our minimum order is 250 copies." Standard production is "4-6 weeks from file approval, plus 6-8 weeks for ocean shipping (or about 1 week for air freight)." Its rough guide says a 6 x 9 inch case-wrap hardcover with 200 pages on coated paper "starts around $4-6 per unit at 1,000 copies." That is PrintNinja's guide for that specification, not a price this site calculated. The same page says that at 250 copies and above, offset hardcovers cost significantly less per unit than print on demand. PrintNinja does not publish the print-on-demand price it is comparing. It includes a free prepress review and an optional physical proof. It does not state a minimum or a rough-guide price for every trim, paper, and page count. Other offset printers' minimums are not stated here, because their pages were not the ones checked.[445]
- 250 copies is PrintNinja's hardcover minimum. It is not a rule on the KDP, IngramSpark, Lulu, or BookVault pages.
- The $4-6 figure is a rough guide at 1,000 copies for one hardcover specification.
03
When does Lulu say an offset run is the one to consider?
Lulu's print-on-demand article, checked 17 October 2026, does not show a publication date. It compares print on demand with offset in its own table. Print on demand is "One copy, short runs, uncertain demand." Offset is "Larger, predictable print runs." Unit cost is "Relatively consistent" for print on demand and "Falls as volume rises" for offset. Inventory is "Not required" for print on demand and "Storage and fulfillment required" for offset. File changes are "Simple" for print on demand and "Not possible" for offset. The article says: "There is no universal quantity at which offset becomes cheaper." It also says the only time to consider a large offset run is if you know the audience and expected sales will justify it. It does not state that sales figure. On the same page Lulu says you will be buying thousands of copies to get to the lower offset unit price. That sentence is Lulu's. It is not PrintNinja's 250-copy minimum, and this page does not average the two into a crossover point.[441][442][445]
- Lulu does not state a copy count where its own print price meets an offset quote.
- A Lulu lead time is not stated on the basics article checked here.
04
What do published examples show by book type?
Checked 9 November 2026. Lulu's print-on-demand article still says there is no universal quantity at which offset becomes cheaper. The rows below are illustrative. Each print-on-demand cell is one figure KDP publishes. Each offset cell is a range PrintNinja prints for the sizes named on its prices page, dated 2 November 2026. Shipping, sales tax, and duties are excluded from those PrintNinja figures. The rows are not the same book, and they are not a point where you should leave print on demand.[439][442][445][555][636][638]
| Book type | Print on demand, one published example | Offset, PrintNinja examples dated 2 November 2026 | What this row does not decide |
|---|---|---|---|
| Text paperback | KDP's 300-page US black-ink paperback example is 4.60 USD a copy. The print-options page states no minimum run. | Softcover examples at 5.5 by 8.5 inches and 6 by 9 inches: 11.93 to 17.84 USD a copy at the 250-copy minimum, and 3.58 to 5.62 USD at 1,000. | At 1,000 copies that offset range sits on both sides of 4.60 USD. The paper and trim are not matched. |
| Text hardcover | KDP's 300-page US black-ink regular-trim example is 9.25 USD a copy: 5.65 plus 300 times 0.012. Re-read 9 November 2026. The page states no upfront inventory. | Hardcover examples at 6 by 9 inches and 8.5 by 11 inches: 19.78 to 25.31 USD a copy at 250, and 6.64 to 8.48 USD at 1,000. | At 250 the offset range is above 9.25 USD. At 1,000 it is below. That is not a rule for your hardcover. |
| Children's book | The KDP hardcover page starts its black-ink table at 75 pages and does not print a picture-book example. | Children's books: 6.96 to 10.05 USD at 250 and 2.14 to 4.94 USD at 1,000. Hardcover children's books: 10.05 to 16.14 USD at 250 and 3.56 to 5.42 USD at 1,000. | No KDP example on these pages sets a crossover for a children's book. |
| Color cookbook | KDP publishes a premium-color hardcover formula on the same page. It does not print a cookbook total, and this page does not compute one. | Cookbooks at 8 by 10 inches and 8.5 by 11 inches: 17.93 to 31.96 USD at 250 and 5.63 to 10.39 USD at 1,000. | A formula is not a quote for an 8 by 10 inch cookbook. |
- A range that sits above a KDP example at 250 copies and below it at 1,000 copies is still two different specifications.
- PrintNinja's earlier rough guide of 4 to 6 USD at 1,000 copies, for one coated hardcover, stays on the hardcover section above. It is not restated as a new price.
05
What does total cost look like at a few quantities?
This table is illustrative. The KDP column extends the published 9.25 USD hardcover example by the number of copies, because that page states a per-copy cost and says you do not pay upfront or hold inventory. KDP does not print these totals. The PrintNinja column uses the totals its hardcover prices page prints for one specification: 6 by 9 inches, 300 pages, 70 lb uncoated, dated 2 November 2026, before shipping, sales tax, and duties. The per-copy figures on that page do not multiply back to the printed totals in every row, so this table keeps the printed total. Divide that total by the copies you will actually sell, not by the copies you print, if some will sit unsold. If you print the 1,000 and sell 400, 8,475 divided by 400 is 21.1875 USD for each copy you sell. The KDP example stays 9.25 USD a copy, because you do not pay for copies nobody orders. Lulu says the time to consider a large offset run is when you know the audience and the expected sales will justify it, and that you will be buying thousands of copies to reach the lower unit price. This page does not turn that sentence into a copy count.[442][445][637][638]
| Copies | KDP example, 9.25 USD times the copies | PrintNinja published total | PrintNinja printed per-copy figure |
|---|---|---|---|
| 250 | 2,312.50 USD | 6,327 USD | 25.31 USD |
| 500 | 4,625 USD | 6,872 USD | 13.74 USD |
| 1,000 | 9,250 USD | 8,475 USD | 8.48 USD |
- One copy is not on the PrintNinja table. The stated hardcover minimum is 250.
- Storage, freight, and the copies you do not sell are still outside both columns.
06
What do these pages leave unknown?
They do not state a quantity at which you should stop using print on demand. They do not give a delivered cost for your trim, page count, paper, and destination. KDP's print-options page and IngramSpark's book-printing page do not state a lead time. BookVault's bulk threshold is not stated on the minimum page. PrintNinja's comparison with print on demand does not include the other price. Storage, freight, and unsold copies are named by Lulu as offset costs, without a dollar figure on the article checked here. The tables on this page are labelled illustrative. They compare named examples. They are not the missing universal quantity.[439][440][442][443][445][636][637][638]
- Price a specific book on the service's calculator or quote, then compare that quote with an offset quote for the same specification.
