Common Uses and Printing Tips
Paper size choices affect layout, margins, envelopes, framing, printer compatibility, and export settings. Even when two formats look close on screen, the physical dimensions can change how much text fits on a page, how images crop, and how comfortable a document feels when printed or bound.
For sharp print output, 300 DPI is the usual target for final artwork, brochures, and photo-heavy documents. Lower resolutions can work for drafts or large-format proofing, but they may look soft when viewed up close or when fine text and line work matter.
If you are preparing a file for print, compare the physical dimensions above with your pixel dimensions, confirm bleed and safe margins, and make sure your printer or print shop supports the selected format before exporting.
