How These Dimensions Are Calculated
spine_width = 80 pages × 0.002500" = 0.2000"
pdf_width = (2 × 5.5") + 0.2000" + 0.25" = 11.4500"
pdf_height = 8.5" + 0.25" = 8.7500"
pdf_width = (2 × 5.5") + 0.2000" + 0.25" = 11.4500"
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.

A short trade-format book at 80–149 pages with cream paper delivers spines between 0.20" and 0.37". The 5.5" × 8.5" trade format with cream paper is a go-to combination for independent literary publishers — the feel matches what readers expect from a quality small-press novel. At 100 pages, cream adds about 0.025" to the spine versus white paper. This difference is invisible to readers but visible to your cover template; always recalculate spine width when switching paper types, even for the same page count.
