A brochure is an informative paper document (often also used for advertising) that can be folded into a template, pamphlet or leaflet. A brochure can also be a set of related unfolded papers put into a pocket folder or packet. Brochures are promotional documents, primarily used to introduce a company, organization, products or services and inform prospective customers or members of the public of the benefits. Brochures available in electronic format are called e-brochures. This format has the added benefit of unlimited distribution and cost savings when compared to traditional paper brochures.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). Brochures are often printed using four-color process on thick, glossy paper to give an impression of quality. Businesses may print small quantities of brochures on a computer printer or on a digital printer, but offset printing turns out higher quantities at a lower cost per unit.

Compared with a flyer, a brochure usually uses higher-quality paper, more color, and is folded.
