Choosing the Correct Ring Binder
The most common mistake made when choosing a binder is selecting the wrong ring size.
Ring binder size (1″, 2″, etc.) is measured based on the size of the ring, not the width of the binder spine.
The overall size of the rings must be larger than the stated inch-size because the ring must go around the contents in order for you to close it.
Round Ring (also called O-Ring)
To determine the sheet capacity of a Round or O-Ring Binder, measure across the inside diameter of the rings. Round Ring is the most common for standard capacity. The ring is usually mounted to the spine.
To determine the sheet capacity of a D-Ring (available as an angled D-Ring or straight D-Ring) binder, measure the straight part of the ring style shape. D-Ring Binders hold up to 25% more paper than a Round Ring. The ring is mounted to the back cover so pages lie flat.
The number of pages of paper (sheet capacity) that a binder can hold depends on the size of the binder (that’s the ring size measured as inches) and the type of ring style.
Sheet capacity will vary somewhat depending on which binder manufacturer one uses as a resource. Avery®, Cardinal®, Samsill®, WilsonJones®, and Business Source™ (our proprietary brand) are among the most common for 3-ring binders.
Ring Binder Sheet Capacity Chart*
|Ring Size||Sheet Capacity|
|1/2″||100 – 125|
|1″||175 – 225|
|1-1/2″||275 – 350|
|2″||375 – 500|
|3″||460 – 625|
*Note: Actual capacity depends on the ring style you choose. Based on 20 pound bond paper.
Use a Presentation Binder for proposals, presentations and reports.
Presentation binders are often called Clearview, Clear view, Clearvue™, or Clear Overlay binders. These binders have a clear vinyl overlay on front, back and spine. Underneath the vinyl you can create separate customized information and insert it as a title page or any other information that you want to display on the front, back and spine.
Use a Reference Binder for frequently used documents like manuals, files and workbooks.
Reference Binders are often called “general use binders.” Because their intent is to be used often, make sure you purchase one that is durable. Typically, reference binders do not include the clear view overlay on the front. They are, however, frequently chosen with inside pockets and a label holder or label sleeve on the spine.
Use a Storage Binder for documents that are not accessed very often like annual records or information you need to archive.
Storage binders are often called specialty binders. Because storage binders are accessed infrequently, they are commonly selected with a feature that allows them to hang (hanging storage binders). Typically, they are chosen with a stiff cover.
