How These Dimensions Are Calculated
spine_width = 500 pages × 0.002252" = 1.1260"
pdf_width = (2 × 6") + 1.1260" + 0.25" = 13.3760"
pdf_height = 9" + 0.25" = 9.2500"
pdf_width = (2 × 6") + 1.1260" + 0.25" = 13.3760"
pdf_height = 9" + 0.25" = 9.2500"
The 0.25" added to both width and height accounts for 0.125" bleed on each side. Your cover image must extend into this bleed area to avoid white edges after trimming.

Books exceeding 500 pages at trade-format (6" × 9" / 5.5" × 8.5") trim sizes are substantial works: complete biographies, reference compendiums, or thick fantasy novels. Spine widths exceed 1.13" and can approach 1.87" at KDP's 828-page ceiling. George R.R. Martin's longer novels match this configuration. The wider spine allows for fully developed spine branding — title, author, and series information without crowding. Confirm the barcode safe area on your back cover does not compress when the total PDF width expands with these larger spine measurements.
