How These Dimensions Are Calculated
spine_width = 72 pages × 0.002500" = 0.1800"
pdf_width = (2 × 8.5") + 0.1800" + 0.25" = 17.4300"
pdf_height = 11" + 0.25" = 11.2500"
pdf_width = (2 × 8.5") + 0.1800" + 0.25" = 17.4300"
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.

Under 80 pages at a large 7" × 10" or 8.5" × 11" trim on white paper targets workbooks, activity sheets, and academic handouts where generous page real estate matters. Spine widths are under 0.18" — too narrow for spine text per KDP rules. The large format suits illustrated instructional content, simple worksheets, and guided journal inserts. Ensure your back cover barcode (2" × 1.2" reserve area) and front cover imagery both fit cleanly with 0.125" bleed and 0.25" safe margin on each panel. Verify dimensions above before designing.
