What Size Is Lulu? (Paperback Trim Sizes)
If you are asking what size Lulu is, the answer is: you pick from Lulu’s supported book sizes when you create a project. Your interior PDF must match that trim and binding — always use Lulu’s current size list and downloadable templates.
Common indie sizes overlap with other PODs — for example many authors use trade sizes near 5 × 8 in, 6 × 9 in, or 5.5 × 8.5 in — but the authoritative source is always Lulu’s own product configurator and help articles for your edition.
InkAlign maps cleanly to this workflow: choose the same standard paperback trim in the app that you selected in Lulu, upload your interior, and process with the engine we tune for Lulu-class, KDP-class, and IngramSpark-class dimensions. Browse trims from the tools hub. InkAlign exists so “which Lulu size?” and “does my PDF match?” are not mystery novels.
