Fantasy novel formatter
Fantasy runs long — and long books are where gutter math, page limits and spine width start to bite. Typeset with the geometry handled.
Fantasy is the genre of 120,000-word debuts and 200,000-word finales, and length is exactly where book geometry gets unforgiving: KDP's inside-margin requirement climbs with page count (0.625in past 500 pages, 0.75in past 700), the platform caps paperbacks at 828 pages, and every extra page is per-copy print cost. Extrapolating from our measurements (~415 words per 6×9 page), a 150,000-word epic runs roughly 360 typeset pages at 6×9 — but 520+ at 5×8, crossing into the next gutter bracket. Ceeryo handles all of it automatically: chapters and scene breaks detected from your manuscript, the Vantage theme's sharper typography suiting the genre, the gutter set from your real count, and the preflight flagging immediately if a trim choice pushes you past a bracket or toward the 828-page ceiling.

How it works
How to fantasy novel formatter in four steps
The fastest way to fantasy novel formatter without manual copy-paste, screenshots, or formatting cleanup.
- Step 1
Upload your manuscript
Drop in the .docx manuscript you have finished writing. Your file is processed only to typeset it and is never used to train models.
- Step 2
Chapters are detected
Chapter openings, scene breaks and italics are found automatically, without changing a word of your text.
- Step 3
The book is typeset
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 your fantasy manuscript (.docx) and get a print-ready interior PDF plus EPUB with long-book geometry handled: gutters that climb correctly with page count, the 828-page KDP ceiling checked, scene breaks and chapter structure preserved. At ~415 words per 6×9 page, 150k words ≈ 360 pages; compact trims can add 45%.
How do I format a long fantasy novel for KDP?
Choose a larger trim (6×9 keeps a 150,000-word epic near 360 pages instead of 520+ at 5×8), let the gutter follow the final page count (KDP requires 0.625in inside past 500 pages), and verify the interior PDF's geometry before upload. Ceeryo does the trim-exact typesetting, bracket-correct gutter and preflight automatically from your Word file.
Long-book math
Epic length changes the rules
Most formatting advice assumes a 250-page book. Past 300 pages the gutter bracket steps up; past 500 it steps again; at 828 KDP stops printing. Fantasy authors hit all three walls first — the tool that sets geometry from your measured count is the difference between uploading once and re-exporting all week.
- Gutter brackets: 0.5" ≤300pp · 0.625" ≤500pp · 0.75" ≤700pp · 0.875" ≤828pp
- 150k words ≈ 360pp at 6×9 (extrapolated from measured 415 w/p)
- The same 150k at 5×8 ≈ 520pp — next bracket, more cost
- Preflight flags the 828-page ceiling before KDP does

Frequently asked questions
My novel is 180,000 words — will it fit?+
At 6×9, roughly 430–450 typeset pages — comfortably inside KDP's 828-page limit with the 0.625in gutter applied automatically. At 5×8 it approaches 630 pages and the 0.75in bracket; the preflight shows both before you commit.
Are maps and images supported?+
Ceeryo is deliberately text-led: chapters, scene breaks and italics. Full-page map inserts are best added by your cover/interior designer after typesetting — image-heavy layouts are out of scope by design.
Which theme suits fantasy?+
Vantage (built for thriller/SF/crime energy) and Marlowe (classic literary) both carry epic fiction well — typeset in each and compare; every purchase includes all themes.
