How These Dimensions Are Calculated
spine_width = 24 pages × 0.002252" = 0.0540"
pdf_width = (2 × 6") + 0.0540" + 0.25" = 12.3040"
pdf_height = 9" + 0.25" = 9.2500"
pdf_width = (2 × 6") + 0.0540" + 0.25" = 12.3040"
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.

A short book at 5.5"–6.14" × 8.5"–9.21" with white paper produces a spine of 0.18" or less. Trade paperback dimensions at minimal page counts are used for pamphlets, academic lecture supplements, and special-edition sampler chapters. The large page area lets you use generous margins and typeset at 12 pt for maximum accessibility. Spine text is not permitted below 79 pages — leave that space clean. Make sure your front and back covers have enough visual contrast at this trim size; the wider format gives more canvas but also more empty space to fill thoughtfully.
