What paper sizes fit in a standard filing cabinet?

Letter-size filing cabinets accommodate 8.5" x 11" documents in standard letter-size hanging folders. Legal-size cabinets accommodate 8.5" x 14" documents and are approximately 15.5"–15.75" wide internally. Some cabinets are convertible — they include a letter/legal converter frame. A2-size and other international formats may require specialty filing solutions. OfficeFurniture2go.com carries both letter and legal options — call 1-800-460-0858.
