The #1 question we often get asked is “What size do I need of (insert product here) in order to fit (insert number of sheets here)?” Since this is such a frequent request, we have made some simple charts to help guide you whether you are using Plastic Bindings, Plastic Coil, Wire-O or Loose-Leaf Binders. It is important to note that when we refer to “sheets” we are referring to the sheet of paper both front and back equaling to one. When we refer to “pages” we are talking about how one sheet of paper is in fact two pages (the front is one page and the back is a second page).
