Handling Thick Spines on 6x9 Books
Thicker Novels like this 300-page volume have a prominent spine (0.676"). Small math mistakes are amplified on books this thick, leading to crooked titles or artwork wrapping around the edges. This template gives you the precise measurements needed to design a bold, readable spine that stands out on the shelf and meets KDP's print tolerances.
Spine Text for 300 Pages
ADVICE: Since your book has 300 pages, the spine width is 0.676 inches, which is wide enough for text. Amazon allows spine text for books with 79+ pages. We recommend using a font size of 10pt-12pt and centering it carefully within the guides provided in this template.
Best use cases for this 6x9 layout
This thicker 6x9 format is ideal for full-length novels, anthologies, manuals and any project where spine branding matters as much as the front cover.
How to design your 300-page Book Cover (3-Step Guide)
This 6x9, 300-page template is built for thick novels and anthologies. Follow these 3 steps to keep the wide spine straight and the title readable on the shelf and as a small thumbnail.
Step 1: Focus on spine and trim guides
Download the 6x9, 300-page file and open it. Pay special attention to the wide spine channel and fold lines, where thick novels most often fail KDP checks.
- Bleed (pink): extend artwork into the bleed so this thick novel trims without visible white edges.
- Spine channel: note the width of the spine guides; your spine title must sit fully between them.
- Barcode block: keep the bottom-right clear of text and key graphics.
Set Up Your Design Project
Create a file at 12.926" by 9.25" to match this thick 6x9, 300-page novel. The 0.676" spine is wide, so plan a short, bold spine title and a clean front cover that still reads clearly when shrunk down on screen.
Overlay and Export
Overlay the PNG guide, paying special attention to the spine channel. Place the spine title fully inside those guides and keep front and back text away from trim lines. Remove the guide layer, export as a high-resolution PDF for print, and quickly check a zoomed-out thumbnail view to confirm the text is still legible.
FAQ for 6x9 Paperback Covers
At 300 pages on White Paper, the spine is 0.676" wide. That gives your book a noticeable presence on the shelf and enough room for a strong, legible spine title.
No. KDP routinely prints 300-page 6x9 paperbacks. The important part is using the precise 0.676" spine width and total cover size so trimming and binding stay within tolerance.
Most publishers stay in the 10–14pt range for spine text on novels, depending on the typeface. Use a clean, high-contrast font and avoid long subtitles that need to be squeezed into the spine.
Yes, but the math will change. Hardcovers use different hinge and wrap values, so you should generate a dedicated hardcover template rather than reusing this paperback file.
