What size of rings do I need to hold my papers?
Choosing the correct ring size for your binder is critical. Too small and your sheets won’t completely fit. Too large and your papers will “swim” in the binder plus cost more money. To help, we have devised this chart to help you determine the right size for your needs. The width of the rings not the spine of the binder is the determining factor for “O-Ring” binders and the length of the straight part of the ring for “D-Ring” binders.
