Tips for 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.

There are two typical types of rings:

  • Round Ring (also called O-Ring): To determine the sheet capacity of a Round or O-RingBinder, 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.
  • D Ring: 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.

Storage Binders

Use a Storage Binder for documents that are not accessed very often like annual records or information you need to archive.
