Most items are sized for standard letter documents — several explicitly state they hold 8.5" x 11" (letter-size) paper or otherwise describe accommodating letter-size documents.

The results show a range of materials including paper, polypropylene (plastic), polyester, bamboo, metal, and fabric across different folders and organizers.

Sheet capacity varies widely: some slim manila folders list about 12 sheets, common plastic or paper folders list around 50–100 sheets, and an expandable organizer is listed as holding up to 1,400 sheets.

Layouts range from simple two-pocket folders to multi-pocket accordion files and desk sorters. Examples include 2-pocket plastic folders, a 19-pocket expanding organizer, portfolios with several internal slots, and a five-slot wooden mail holder.

Several folders include tab positions and inserts for labels; common setups shown are three-tab positions on manila folders and five-tab positions on hanging letter-size folders.

The expandable accordion organizer is described as having 19 interior pockets, a very large sheet capacity (listed as 1,400 sheets), holding standard letter paper, and features such as a thumb-turn closure and a carrying handle.
