What size file cabinet do I need for letter vs. legal documents?

Most home-office cabinets in this roundup accommodate letter, legal, A4, and F4 hanging folders in their full file drawers, but legal-size documents require the drawer's interior width to be at least roughly 15 inches. If you primarily store letter-size files, a narrower vertical pedestal saves floor space; if you handle legal or mixed sizes, confirm interior drawer dimensions before buying.
