A tri-fold is a type of brochure or pamphlet that is folded into three sections, creating six panels for content. This design is popular for marketing materials, as it allows for organized presentation of information while being compact and easy to distribute. The tri-fold format is often used for advertisements, event promotions, and informational handouts. To create a tri-fold, a single sheet of paper is typically divided into three equal parts, with two folds that meet in the center. This layout provides a clear structure for presenting details about products, services, or events, making it an effective tool for communication in various settings, such as businesses and educational institutions.
