What is the difference between lateral and vertical file drawer depth in a mobile pedestal?

Mobile pedestal file drawers are almost exclusively vertical (files hang front-to-back), not lateral (files hang side-to-side). A standard vertical file drawer in a pedestal accepts letter-size files (8.5" × 11" paper, filed with the long edge forward) or legal-size files (8.5" × 14" paper) depending on the drawer width. Letter-size drawers are the most common in commercial pedestals (12" nominal width). Legal-size drawers require a wider pedestal (typically 15"–18" wide). If your office uses primarily legal-size paper, verify the pedestal accommodates legal drawers before purchasing.
