How These Dimensions Are Calculated
spine_width = 600 pages × 0.002252" = 1.3512"
pdf_width = (2 × 8.5") + 1.3512" + 0.25" = 18.6012"
pdf_height = 11" + 0.25" = 11.2500"
pdf_width = (2 × 8.5") + 1.3512" + 0.25" = 18.6012"
pdf_height = 11" + 0.25" = 11.2500"
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.
