A4 for most of the world (210×297 mm), Letter for US workflows (8.5×11 in). Mismatched sizes jam office printers — normalize before bulk printing.
Scales to fit with margins preserved by default; content never crops silently. Check one dense page — tiny original text may shrink below readable size.
Each page scales to the target independently, so mixed sets normalize uniformly. Verify landscape pages didn't rotate unexpectedly.
