How does bookcase depth affect where you can place it in an office?

Standard office bookcases are 12" deep — enough for letter-size binders and most books. This means a bookcase placed in a room takes a 12" footprint plus clearance in front for access. In hallways, a 12" bookcase plus 28"–36" of clearance means you need at least 40"–48" of corridor width to legally and practically place one. In small offices (10'x10'), a bookcase along the wall only costs 12" of depth off one dimension — totally manageable. Deeper bookcases (15"–18") are less common but needed for legal-size materials.
