What Size Is IngramSpark? (Paperback Trim Sizes)
IngramSpark does not ship one universal book size. You choose a trim size (for example common trade sizes like 5 × 8 in, 5.5 × 8.5 in, or 6 × 9 in — always confirm against IngramSpark’s current list and cover calculator). Your interior PDF must match that trim exactly.
After you pick a trim, download IngramSpark’s official interior and cover templates for that size and page count. Then build or export your interior so the PDF dimensions and margins line up — “close enough” is how expensive proof cycles start.
InkAlign makes the geometry step repeatable: choose your standard paperback trim in the app, upload your PDF, and process with the same engine we tune for IngramSpark-compatible industry sizes. Browse all trim-specific entry points from the tools hub. Authors routinely tell us InkAlign saves the day when templates and design tools disagree by a few points — the free scan shows it before you commit.
