Paper clips are easy to overlook in a supply order because they all appear small and inexpensive. In practice, different clip designs grip differently, create different bulk on documents and can mark paper surfaces. The right clip depends on stack thickness, reuse and the kind of filing system.
Three clip families
| Clip type | Mechanism | Practical use |
|---|---|---|
| Wire paper clip | Bent wire holds sheets together by pressure | Small document sets and temporary sorting |
| Fold-back / binder clip | Spring steel jaws with folding handles | Medium to thick stacks; can hang documents by handles |
| Bulldog clip | Hinged gripping jaws, often with an extended mouth | Holding papers on boards, desks or reusable fixtures |
Know which measurement is advertised
A clip's listed width is not its paper-stack capacity. For example, a small binder clip may have a jaw width of about 3/4 inch but grip a stack substantially thinner than that. Read both dimensions and verify with the actual material, especially for cardstock or laminated sheets.
When not to use a clip
Archival records and fragile papers may need different handling than everyday handouts. A metal clip can leave impressions or rust if stored badly. For permanent filing, folder systems and protective sleeves may be a better choice than an oversized clip that bends pages.
Purchasing quantities and storage
Clips may be sold by dozen, box or bulk carton. Convert to pieces per package, and consider having a limited approved size selection rather than accumulating many nearly identical variations. Keep clips dry and separated by size in labeled bins so staff can easily find the right option.
School purchasing checklist
- Estimate typical document stack thicknesses.
- Choose wire, fold-back or bulldog grip by task.
- Read jaw width and actual capacity separately.
- Compare per-piece cost across different pack sizes.
- Keep a small range of standard sizes in office supply cabinets.
Frequently asked questions
Does a one-inch clip hold one inch of paper?
Not necessarily. Clip width and opening capacity are different measurements.
Are binder clips and bulldog clips the same?
The names sometimes overlap in retail listings, but designs vary. Compare jaw and handle construction.
