All About 3-Ring Binders: Types, Features, and How to Choose the Right One

Posted on May 8, 2018 by Alyssa Ochs

If you walk into any office, school, storage room, or performance stage, chances are that you’ll see a few 3-ring binders on the shelves or lying around. The 3-ring binder is certainly no newcomer to the office product scene, but they have become more specialized to accommodate certain tasks and industries much better. The history of the 3-ring binder dates back to 1854, when Henry T. Sisson of Providence, Rhode Island filed for a patent for both 2-ring binders and 3-ring binders. Sisson’s design came after the realization that loose-leaf paper was difficult to protect and organize on its own.


Not only did these new creations hold paper together in a convenient way, but they also protected important documents, made the contents more portable, and offered a more professional overall appearance.Although the very first 3-ring binders had binding made of heavy cardboard, modern 3-ring binders are typically made of plastic, polypropylene, PVC, or paper overboard. Today’s version of the 3-ring binder comes in a wide variety of colors and sizes, with special features to suit different purposes.

To get a better sense of what these features are, let’s first take a look at the components of a 3-ring binder, binder types, and how to choose the best 3-ring binder for your purpose.



Types of 3-Ring Binders

If you think that all 3-ring binders look and perform the same, then you probably haven’t yet browsed our selection here at OnTimeSupplies. In addition to standard 3-ring binders, you can choose specialty binders that come in large and small sizes. View binders are commonly used for training materials and have customization options for the front cover, back cover, and spine. Some professional portfolio binders even have a zipper closure for added security and durability.

Meanwhile, pressboard data binders and post binders are often used for accounting records, display binders are used to exhibit awards and presentation materials, and punch-less binders secure documents without the need for hole punches. Some binders are also made with recyclable materials to help you reduce your landfill waste, which is great if you don’t plan to use your binders long-term or reuse them over and over again.

Here are some binders that we recommend: 

Key Features of a 3-Ring Binder

3-Ring Binder Thickness

Since the standard size of loose-leaf paper is 8.5 inches by 11 inches, most 3-ring binders are about 10 inches wide and 12 inches tall. While this measurement is fairly consistent, binder thickness can vary greatly from one product to the next. Thick 3-ring binders offer more space to store records for longer periods of time or for an entire product line. Meanwhile, thin binders are ideal for school reports, specific projects, and one-time events.

3-Ring Binder Ring Size and Type

The amount of paper you want to put in your binder dictates the ring size that you need. These rings vary in size from about a half inch to three inches for most 3-ring binders. You can measure the diameter of the ring to determine its paper capacity. One-touch binder rings open easily with just one hand, while gap-free binder rings make page turning easy by eliminating snags and tears. We also well back-mounted binder rings to help sheets of paper lie flat rather than curving with the ring.

On the surface, 3-ring binders appear simple enough. But it’s important to understand the parts of a 3-ring binder to choose the right one for your needs.

3-Ring Binder Pockets

Binder pockets are great for organizing loose papers, keeping track of receipts, and stowing away important documents until you have time to 3-hole punch them. Many binders have pockets in the front and back to use for these purposes. Some professional binders even have business card slits to store your own business cards or collect them from clients and customers that you meet.

3-Ring Binder Covers

Binders used for presentations or reports that will be shared with others often need a cover to identify the documents inside and create a professional appearance. One great cover option is the non-stick cover, which is designed to prevent ink stains and smudges so that you can reuse your binders over and over again.

For example, our very own CEO, Miles, was recently contacted by a customer who was a composer, music director, and accompanist who was looking for 3-ring binders that would enable her to turn sheets of music quickly and smoothly while playing songs. Not only did Miles recommend gap-free ring binders that would be perfect for this purpose, but he sent several options to the music director the very next day to try out.
