Choose Letter when
- The document is a normal office letter, resume, or form
- The recipient expects 8.5 × 11
- The printer has only a standard Letter tray
Choose Legal when
- The form specifically says 8.5 × 14
- A long table or signature section needs more room
- Filing and scanning workflows support Legal
Because the widths match, a print preview can look plausible even when the wrong tray is selected. Check the page-size label, not only the thumbnail.
