How to Choose the Right Size Binder

  • Written by Printing Professional

We’re all familiar with the “snap” of the rings in a binder when it’s being closed. That’s about the only time we think about the O-rings or D-rings, but these rings are what we should think of when buying or ordering binders. It’s not the width of the binder spine that determines how much paper will fit in a binder. It’s the size and type of the ring.

As shown in the illustration above an O-Ring is sized by determining the diameter. Standard O-Rings sizes are from 1/2 an inch to three inches. D-Ring sizes are measured along the straight part. The length of D-Rings are usually between one to three inches. D-Rings actually hold up to 25% more sheets than O-Rings.

You can actually figure out how many sheets can be held in a binder simply by knowing the measurement of these rings. The table below shows the capacities based on average sheets of paper. Thicker paper or dividers will mean less can fit in the binder. It’s better to order a larger binder than a smaller one for your project. Even if it’s a bit too big, you’ll have extra room to turn the pages or even insert other sheets at a later time.

At Accent Printing, we print a lot of presentation material and do the kitting and assembly services for our clients. We can help if you have any further questions about binders.
