Format Your Novel as a 5×8 Book
The compact trim classic fiction is printed at. Upload your manuscript and get a 5×8 interior with the type sized for the smaller page.
5×8 inches is the trim of mass-appeal fiction — thrillers, romance, and novellas feel 'like a real paperback' at this size. The smaller text block changes everything about the typography: line length, type size, margins, and gutter all have to be retuned, not just scaled down. Ceeryo's themes are built per-trim, so at 5×8 you get a properly proportioned page, the KDP gutter for your page count, and chapter design that fits the smaller canvas — from the same Word upload, with an EPUB alongside.

In short
5×8 in is the classic compact fiction trim. It needs retuned typography, not scaled-down 6×9 pages: shorter lines, adjusted margins, and a gutter for the higher page count. Ceeryo typesets your manuscript natively at 5×8 and verifies the result against KDP's requirements.
Should my novel be 5×8 or 6×9?
Shorter fiction (under ~60,000 words), novellas, and genre paperbacks usually suit 5×8 — it feels like traditional fiction and keeps thin books from looking thinner. Longer books usually suit 6×9, which fits more words per page and costs less to print per copy. Both trims are one click in Ceeryo, so you can compare page counts before deciding.
Small page, real typography
Retuned, not shrunk
A 5×8 page set with 6×9 metrics reads cramped. Ceeryo's themes adjust measure, indents, and opener proportions for the smaller text block, so the page looks designed for 5×8 — because it is.

Frequently asked questions
Will 5×8 make my book more expensive to print?+
Per-copy cost depends on page count, and 5×8 fits fewer words per page than 6×9, so the same manuscript has more pages and costs slightly more per copy. For shorter books the difference is small and the format fits the genre.
Can I preview both trims?+
Yes — run the same manuscript at 5×8 and 6×9 and compare the page counts and feel before you commit.
Is 5.25×8 also supported?+
Yes — 5×8, 5.25×8, 5.5×8.5, 6×9, and A5 are all available in the trim picker.
