- Paperback
- Black and white, all eight sizesRecommends PDF/X without ICC profiles
- Five sizes, no bleed
The table assumes you built the book with a cover. Without one, the EPUB has no cover picture, and Google Play Books asks for one inside it.
Amazon KDP
- Print interior and cover. We set both to KDP's measurements: the eight paperback sizes, the margins for your page count, and the spine for your paper. KDP prefers PDF/X-1a and also takes other PDFs, such as the PDF/A we make.
- Hardcover. KDP prints hardcovers in four of our sizes, from 75 to 550 pages. Ask for a hardcover cover and we make one beside the paperback's, from the same design. It follows KDP's hardcover measurements: the larger boards, the wrap around them and a hinge beside the spine that the words keep out of. The interior is the same file. We haven't had a hardcover printed yet, so order a proof copy before you publish.
- Ebook. KDP takes an EPUB, and its cover as a TIFF or a JPEG. We make the cover about 2,560 pixels tall, the height KDP suggests, and give it to you as a JPEG.
IngramSpark
- Print interior. All eight of our sizes are IngramSpark sizes. For black-and-white pages its guide recommends PDF/X and asks for no ICC profiles, the color descriptions some programs write into a PDF. Ours is not PDF/X and carries them. For color pages, PDF/X is required.
- Margins. Everything on our pages, the running head and the page number included, stays at least 0.5 inch from every edge, as IngramSpark asks.
- Print cover. IngramSpark asks for a cover made on its own template, as a PDF/X, with its barcode. Ours is drawn to KDP's spine and barcode, so it has to be laid out again.
- Ebook. IngramSpark takes EPUB 3, and no picture inside it may be larger than 3.2 million pixels. The cover we put inside the EPUB is a smaller copy made to stay under that, and the build warns you about a picture of yours over it.
- Ebook cover. IngramSpark asks for a JPG in RGB, at least 1,600 by 1,873 pixels. Ours is at least 1,600 pixels wide and about 2,560 tall.
Lulu
- Print interior. Lulu prints five of our eight sizes: 5 × 8, 5.5 × 8.5, 6 × 9, 6.14 × 9.21 and 7 × 10 inches. At those sizes our interior without bleed is the kind of file Lulu's guide recommends. With bleed it isn't, because Lulu wants bleed on all four edges.
- Print cover. Lulu works out the spine its own way and gives you a template for it, so our cover has to be laid out again.
- Ebook. Lulu warns that its stores may refuse pictures over 2 million pixels, and the cover inside our EPUB is larger. Lulu also distributes ebooks in English only.
- Ebook cover. Lulu's cover upload page asks for a JPG or PNG of at least 625 by 1,000 pixels and up to 5 MB, which ours meets.
Apple Books, Google Play Books and Kobo
- Apple Books takes EPUB 3. It asks for the cover as a JPEG or PNG in RGB, at least 1,400 pixels on the short side, and for no picture inside the book over 5.6 million pixels. Ours meet both, and the build warns you about a picture of yours over that limit.
- Google Play Books takes EPUB 3. It wants the cover inside the EPUB and the file checked with EPUBCheck, and ours is. A cover sent on its own is optional, as a JPEG or PNG of at least 640 pixels.
- Kobo takes EPUBs up to 100 MB. For the cover it says a JPG works best and a PNG is also fine, up to 5 MB. Our JPEG is well under that. The PNG of a photographic cover can come close to it.
Books in Turkish and other languages
KDP doesn't list Turkish, in print or as an ebook, and Lulu distributes ebooks in English only. Google Play Books accepts books in all languages, Apple Books lists Turkish, and Kobo takes books in virtually any language.
Other printers
Every printer publishes its own sizes and file rules. In Germany, for example, tolino media asks for PDF/X-3 with a trim box, and epubli for 3 mm of bleed on all four edges. Our print files don't meet those as they are, so read a printer's rules before you upload.
How we checked
We compared each file with the platform's own help pages and guides, listed below with the day we read them. We haven't tested every platform with an upload, and each one decides what it accepts. When a platform changes its rules, we read them again and change this table.
