What is the standard exterior width of flat-file cabinets?

The most common exterior widths of commercial flat-file cabinets are: 34"–36" wide (for ARCH D / 24"x36" documents); 42"–44" wide (for 36"x48" documents); and 50"–52" wide (for 42"x54" or E-size documents). Exterior dimensions are always wider than interior drawer dimensions due to wall thickness. Confirm the interior dimensions match your largest document format.
