5.25 × 8 book formatter
The classic compact fiction trim — between mass-market and trade — typeset with exact geometry and a gutter matched to your page count.
5.25×8 is the quiet classic of fiction trims: noticeably more compact than 6×9 without the pocket-book feel of 5×8, and a favorite for literary fiction and rereleases. It is also where page-count math starts to matter — the same 90,000-word manuscript that sets 217 pages at 6×9 measured 291 pages at 5.25×8 in our engine, which changes both your per-copy print cost and the KDP gutter bracket your book falls into. Ceeryo typesets your .docx at exactly 5.25×8, detects chapters and scene breaks from the document itself, applies the interior theme's drop caps and running heads, and sets the inside margin from the final count — then shows the full KDP preflight passing before you pay.

The fastest way to 5.25 × 8 book formatter without manual copy-paste, screenshots, or formatting cleanup.

Trim size, margins and gutter, running heads, drop caps and chapter openers are set as a real book interior.
- Step 4
Download print PDF + EPUB
A print-ready interior PDF at your chosen trim size plus a clean EPUB, checked against the geometry KDP enforces.
In short
Upload a .docx and get a print-ready 5.25×8 in interior PDF plus EPUB: exact trim dimensions on every page, gutter chosen from your real page count per KDP's brackets, and a preflight that proves it. Expect roughly 34% more pages than 6×9 — a measured 90,000-word novel ran 291 pages at this trim.
How many pages is a book at 5.25 x 8?
Roughly a third more than at 6×9. Our measured 90,000-word test manuscript set 291 pages at 5.25×8 versus 217 at 6×9 — around 310 words per typeset page. More pages means a higher per-copy print cost and, past 300 pages, the next KDP gutter bracket.

Frequently asked questions
Why choose 5.25×8 over 5×8?+
A slightly wider text block, so fewer pages (291 vs 314 for our 90k-word test) and a touch more air in the margins — many readers find it the more comfortable compact trim.
Does my Word file need to be set to 5.25×8?+
No. Upload the manuscript as-is; the typesetter builds pages at the trim you choose regardless of the document's page setup.
Will KDP accept the output?+
The preflight verifies the exact checks KDP applies to geometry: trim match, page range, gutter bracket and embedded fonts — all shown passing before download.
