How These Dimensions Are Calculated
spine_width = 310 pages × 0.002500" = 0.7750"
pdf_width = (2 × 6") + 0.7750" + 0.25" = 13.0250"
pdf_height = 9" + 0.25" = 9.2500"
pdf_width = (2 × 6") + 0.7750" + 0.25" = 13.0250"
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.

Trade-format books at 300–499 pages with cream paper produce spines of 0.75"–1.25". A 400-page cream book has a full inch of spine — enough for a two-line spine design combining title and author name in complementary fonts. This configuration is strongly associated with literary fiction and independent press fiction in English-speaking markets. Premium spine presence comes at a small cost: cream paper at 400 pages adds roughly 0.10" to total PDF width versus white paper. Account for this in any shared design template spanning multiple print editions.
