Format Your Manuscript as a 6×9 Book
6×9 in is the standard trade-paperback trim. Upload your Word manuscript and get a 6×9 interior PDF with the margins and gutter exactly right.
6×9 inches is the most common self-publishing trim size — the standard for trade paperbacks on Amazon KDP and IngramSpark. Getting it right takes more than setting the page size in Word: the PDF must be exactly 6×9 on every page, margins must mirror between left and right pages, the inside gutter must grow with your page count, and every font must be embedded. Ceeryo handles all of it: upload your .docx, pick an interior theme, and download a 6×9 interior that passes KDP preflight, plus an EPUB for the ebook edition.

In short
A 6×9 book interior needs exact 6×9-inch PDF pages, mirrored margins, a gutter sized to page count (0.375"–0.875" per KDP's table), and embedded fonts. Ceeryo produces that from your Word manuscript in minutes, with a preflight report verifying each requirement.
What margins does a 6×9 book need?
For a 6×9 paperback on KDP with no bleed, outside/top/bottom margins must be at least 0.25" (Ceeryo uses roomier 0.5–0.75" for comfortable reading), and the inside gutter depends on page count: at least 0.375" up to 150 pages, 0.5" to 300, 0.625" to 500, 0.75" to 700, and 0.875" to 828. Ceeryo computes this automatically from your book's real page count.
Why 6×9
The default trim for a reason
6×9 fits more words per page than smaller trims, which lowers page count and printing cost per copy — usually the best royalty math for novels over ~60k words. If your book is shorter, a 5×8 trim reads more like traditional fiction; both are one click here.
- ~320 words per page in a readable 11pt serif
- Lower printing cost per copy than smaller trims for long books
- Supported by KDP, IngramSpark, Lulu, and Barnes & Noble Press

Frequently asked questions
Is 6×9 right for my book?+
For most novels and nonfiction over ~60,000 words, yes — it is the standard trade size with the best printing-cost math. Short novels and novellas often look better at 5×8; both are available in the same tool.
Do you add bleed?+
Text-only interiors don't need bleed, and KDP prefers no-bleed for them. The pages are exact trim size — which is what the previewer checks.
Can I switch trims later?+
Yes — re-upload and pick a different trim; the engine recomputes margins, gutter, and page count for the new size.
