What you need to know
US Letter (8.5×11 inches) is the default paper size for printers, copiers, and software in the United States, Canada, Mexico, and several Latin American countries. Outside of these regions, A4 (210×297mm) is the standard. The two sizes are similar but not identical — Letter is slightly wider (8.5" vs 8.27") and shorter (11" vs 11.69") than A4.
When designing documents that need to work in both US Letter and A4 formats, the safest approach is to use A4 dimensions (the narrower format) with slightly reduced margins. Most content will fit both pages without reflowing. If you're targeting only North America, design for Letter. If international, design for A4.
US Letter paper is part of the ANSI paper size system (ANSI A). The larger sizes in this system are Tabloid/Ledger (ANSI B, 11×17"), C (17×22"), D (22×34"), and E (34×44"). Unlike ISO A-series, the ANSI sizes don't share a consistent aspect ratio, so scaling between sizes isn't as clean.
