Pocket Folders are for holding multiple documents and are used for handing out proposals and/or informational material. These are usually of the size to hold regular sized documents i.e. either the European A4 (8.25" x 11.75") or US Letter (8.5" x 11") sizes. The usual standard is 9" x 12" with 4" high pockets, though custom sizes can be made for your requirements.
