What are the standard ANSI drawing sizes I should use to select a flat-file cabinet?

ANSI drawing sizes commonly stored in flat-file cabinets: ANSI A (8.5"x11"), B (11"x17"), C (17"x22"), D (22"x34"), E (34"x44"). ISO/architectural sizes (A0–A4) are also common. For most engineering and architectural work, choose a flat-file cabinet with interior drawer dimensions of at least 30"x42" to accommodate D and E size drawings.
