Question: National FAQ: "One two-inch or smaller standard binder" should refer specifically to the rings in the binder being two inches or smaller, correct? (section: 2 / part: / paragraph: a / sub-paragraph: / line: 1)
Response: Yes, the standard for measurements of a binder are based upon the inner size of the rings. For round ring binders, the size is determined by measuring the inside diameter of the ring(s). D-ring and slant-d ring binders are measured by the straight edge of the ring.
