How to select the best ring style and size for your Legal Binders Now

D-Ring BinderWhen selecting whether to use a round ring or D-ring construction in your binder, you need to consider two factors:

  • the number of pages that will be stored in the binder
  • whether the binder will be heavily used.

D-ring binders have 25% greater capacity than round ring binders and also allow the pages to lie flat. They are used for applications that require frequent access to documents and for storage and organization of a larger number of documents in the binder. Estimated capacities for the different ring sizes are:
