True-Proportion Paperback Mockup with 0.25″ Slim Spine
Present your slim paperback designs accurately with this 6×9 inch softcover book mockup set, created using true book proportions instead of exaggerated or generic thickness.
Featuring a realistic 0.25″ (6.35 mm) spine width, this mockup is designed specifically for short-format publications, where accuracy matters as much as aesthetics.



Built with True Book Proportions
Most book mockups exaggerate spine thickness to “look better.”
This one doesn’t.
This mockup is carefully proportioned to reflect how a real 6×9 slim paperback actually looks in print — helping your presentation feel honest, intentional, and professional.
Perfect when:
-
You’re presenting to clients
-
You’re selling training materials or courses
-
You want realistic expectations before printing
Slim Spine — Correct by Design
The 0.25″ spine width realistically represents books of approximately:
80–120 pages
(depending on interior paper stock)
This makes the mockup ideal for slim books by design, not books that accidentally look thin.
