A Brochure (also referred to as a pamphlet) is a leaflet. Brochures are advertising pieces mainly used to introduce a company or organization, and inform about products and/or services to a target audience. Brochures are distributed by mail, handed personally or placed in brochure racks.
The most common types of single-sheet brochures are the bi-fold (a single sheet printed on both sides and folded into halves) and the tri-fold (the same, but folded into thirds). A bi-fold brochure results in four panels (two panels on each side), while a tri-fold results in six panels (three panels on each side).
Other folder arrangements are possible: the accordion or “Z-fold” method, the “C-fold” method, etc. Larger sheets, such as those with detailed maps or expansive photo spreads, are folded into four, five, or six panels. When two card fascia are affixed to the outer panels of the z-folded brochure, it is commonly known as a “Z-card”.
