How These Dimensions Are Calculated
spine_width = 390 pages × 0.002500" = 0.9750"
pdf_width = (2 × 5.5") + 0.9750" + 0.25" = 12.2250"
pdf_height = 8.5" + 0.25" = 8.7500"
pdf_width = (2 × 5.5") + 0.9750" + 0.25" = 12.2250"
pdf_height = 8.5" + 0.25" = 8.7500"
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.
