To format a horror novel for IngramSpark, use a 5”×8” or 5.25”×8” trim on cream paper, export as PDF/X-1a:2001 with embedded fonts, and set a 50–55% wholesale discount for bookstore placement. Horror has a dedicated section in most independent bookstores — it’s one of the few genres where physical browsing drives discovery more than algorithms. IngramSpark’s distribution puts your horror novel on those shelves. A 75,000-word horror novel runs ~320 pages at 5×8 or ~290 pages at 5.25×8.

Why compact trim works for horror
The 5×8 trim creates a physical reading experience that enhances horror:
- Smaller book = closer to your face — text fills more of your visual field
- Pages turn faster — shorter lines mean quicker reading, building tension
- Intimacy — the book feels personal, private, almost confessional
- Mass-market nostalgia — readers who grew up on Stephen King paperbacks associate this size with horror
At 5×8, a 75K-word horror novel produces ~320 pages — substantial enough to feel like a real book, compact enough to feel dangerous.

PDF/X-1a for horror
Standard IngramSpark requirements apply:
- PDF/X-1a:2001 compliant
- All fonts embedded (no linked fonts)
- Grayscale color space for B&W interior
- Page size exactly matches trim
- Even page count
- No transparency (flatten all layers)
Horror novels are text-only interiors — the PDF/X-1a export is straightforward. The common rejection is fonts not embedded. See IngramSpark PDF/X-1a troubleshooting.
Cambric exports PDF/X-1a for IngramSpark automatically. Format your horror novel with tight spacing and clean scene breaks, then export for both KDP and IngramSpark from the same manuscript.
