What are the standard interior dimensions of a lateral file cabinet drawer?

A standard 36" wide lateral file drawer interior is approximately 34"–35" wide × 17"–18" deep × 10"–11" high (for a file drawer). A 42" wide lateral drawer interior runs approximately 40"–41" wide with similar depth and height. These dimensions accommodate hanging folders in either orientation and allow for a 2"–4" follower block at the back. Box drawers are shallower — typically 4"–5" high — and are used for supplies rather than files. FindOfficeFurniture.com has lateral files in all standard widths — call 888-719-4960 for the best deals.
