Match the Folder to the Equipment

Top Tab vs. End Tab File Folders

The most important first choice is tab orientation. Top tab and end tab folders may hold the same paper size, but they are designed for different filing equipment.

Top tab file folders in assorted colors

Read From Above

Choose Top Tab

  • Files are stored upright in drawers or boxes
  • Labels need to remain visible from above
  • Traditional office filing is already in place
  • Common in desks, lateral files, cabinets, and portable boxes

End tab file folders for shelf filing

Read From the Side

Choose End Tab

  • Files are stored on open shelving
  • Labels are read from the aisle or side
  • Color coding, year labels, or barcodes need to stay visible
  • Common in medical, legal, insurance, and records departments

How to Choose the Right File Folder Features

Once the filing orientation is correct, compare the features that control label visibility, capacity, document security, and durability.

Tab

Tab Style

Choose top tab or end tab first, then compare straight-cut, 1/3-cut, 1/5-cut, reinforced, and specialty tab configurations.

Size

Letter or Legal

Match the folder to 8-1/2" x 11" letter documents or 8-1/2" x 14" legal documents and compatible storage equipment.

Hold

Fasteners

Two-prong fasteners secure punched pages in a fixed order while allowing documents to be added as the record grows.

Grow

Expansion

Expandable folders and pockets provide extra capacity for thick reports, project files, statements, and growing records.

Split

Dividers

Classification folders divide one file into multiple sections for cases, personnel files, contracts, projects, and medical records.

Life

Material

Choose standard stock for everyday use, heavier stock or pressboard for active files, or plastic for tear and moisture resistance.

Get the Size Right

Letter-Size vs. Legal-Size File Folders

Folder size refers to the paper the folder is designed to hold-not simply the folder's outside dimensions. Confirm both the document size and the available cabinet or shelf space before ordering.

8-1/2" x 11"

Letter-Size Folders

Typical folder width: approximately 11-3/4"

Best for office records, invoices, personnel files, correspondence, school records, and most everyday business documents.

8-1/2" x 14"

Legal-Size Folders

Typical folder width: approximately 14-3/4"

Best for contracts, court filings, real-estate documents, government records, and other longer paperwork.

Overall folder dimensions vary by tab style, expansion, hanging rails, pockets, and manufacturer. Check the measurements on the individual product page when cabinet clearance or shelf fit is critical.

Control the Contents

Pockets, Fasteners & Dividers

Choose the internal features according to whether the file contains loose pages, punched documents, or several document groups that must stay together.

Pockets for Loose Documents

Pockets hold unpunched papers, receipts, photographs, forms, and small documents that could slip out of a standard folder.

Shop Pocket Folders →

Fasteners for Secured Pages

Two-prong fasteners keep punched pages attached and in order. Common placements include the inside front and inside back covers.

Dividers for Multi-Part Files

Built-in dividers create multiple filing sections inside one folder for legal cases, personnel records, projects, contracts, and medical records.

Match Durability to the Workload

File Folder Materials & Durability

Heavier material is not always necessary. Match the folder construction to document volume, handling frequency, moisture exposure, and how long the record must remain in service.

If you are replacing an existing filing system, match the material, color, tab position, size, expansion, and fastener layout before changing folder styles.

↑ Back to Categories

11-Point StockEconomical everyday material for light-to-moderate document volume.
14-Point StockMore rigid material for active files, heavier contents, and frequent handling.
Pressboard / HeavyweightGreater structure for classification folders, expanding files, and long-term records.
Plastic / PolyTear- and moisture-resistant construction for mobile or high-contact records.

File Folders FAQs - Sizes, Types, Office Uses

The most common file folder types include top tab folders, end tab folders, hanging folders, classification folders, expandable folders, file jackets, folders with fasteners, plastic folders, and two pocket folders. Top tab and hanging folders are most common for drawer filing, while end tab folders are used for shelf filing systems.

Letter size folders fit 8.5" x 11" paper and are the most common. Legal size folders fit 8.5" x 14" documents and are typically used in legal and government offices.

Top tab file folders are made for file drawers and file boxes where you read the label from the top. They’re common for everyday desk and cabinet filing and come in letter or legal sizes with options like fasteners and colored tabs for indexing. End tab (side tab) folders place the tab on the short side so labels are visible from the side on open-shelf systems. They’re preferred for high-density shelf filing in medical, legal, and administrative environments because they support color-coding, barcodes, and fast, side-read retrieval.
