What to know about 5 × 8 on KDP
5 × 8 in is a compact regular trim. Each page holds less text than 6 × 9, so the same manuscript runs to more pages, and the spine gets wider. Check your final page count before you lock the cover.
- Regular trim. No wider than 6.12" and no taller than 9", so 250 pages cost $4.00 to print in black and white and $17.25 in premium color on Amazon.com. Compare every marketplace.
- Page limits. White paper 24–828 pages, cream 24–776, groundwood 24–812, standard color 72–600, premium color 24–828.
- Spine text. Allowed from 80 pages. At 80 pages on white paper the spine is 0.180", which leaves 0.055" for text after 0.0625" on each side.
- Interior with bleed. If your interior images bleed, set the page size to 5.125" × 8.25" (trim + 0.125" wide, + 0.25" tall).
- Hardcover. KDP doesn't offer 5 × 8 as a hardcover size; this page covers paperbacks.
