Overall dimensions vary by model. Typical ranges are: heights about 3.7 inches to 11.75 inches, widths about 9.4 inches to 14.5 inches, and depths about 6.5 inches to 18.13 inches.
Many accept standard letter-size hanging folders (often with a ledge) and legal-size hanging folders; at least one model specifically notes compatibility with both A4 and letter-size papers.
Many are designed for space-saving stacking: you’ll see grooves or reinforced lids and bodies for stability and dedicated stacking tabs to lock boxes together for safe, vertical storage.
Some lids include an organizer top with divided compartments (for pens, clips, and small supplies), commonly shown as a 4-compartment divider.
Common materials include recycled fiberboard/cardboard, plastic (often polypropylene), and steel.
Available styles include hinged flip-top lids, snap-tight or latching lids (some with a lock-ready spot), lids with organizer compartments, and open-top or crate-style designs.
Common portability features are built-in cut-out handles or separate sturdy carrying handles (sometimes attached to the lid) to make lifting and transporting easier.
