Folded leaflets are printed advertising or information publications, usually folded into several parts. They are used to provide structured information about a product, service, event or other topic. Leaflets are widely used in marketing campaigns as they allow content to be presented in a visually appealing way. 

Leaflets allow you to convey key information in a clear and attractive way to encourage action – for example, to visit a shop or order a service. They also provide an opportunity to creatively differentiate yourself from competitors through design, colour palette and paper choice.

Folded leaflets are used:

• In business communication – for the presentation of company services or products, for the promotion of special offers, for the launch of new products on the market. 
• In events – conferences, exhibitions, seminars, leaflets help to present key information to visitors effectively. 
• In the public sector – used as information publications on social programmes, educational initiatives, healthcare or other relevant topics. 
• In the tourism sector – hotels, travel agencies, museums use leaflets to inform tourists about attractions and services.

• Presenting information in a structured way. Leaflets allow for a structured and clear presentation of information, usually covering essential items such as company introduction, descriptions of services or products, contact information.
• Easy distribution. Leaflets are compact and easy to distribute in a variety of places: events, exhibitions, points of sale, mailboxes, direct to customers. They can be placed on tables, shelves or hand delivered.
• Effective marketing tool. It is one of the cheaper forms of advertising that allows you to reach a wide audience. Well-designed leaflets can create a professional image and attract potential customers.

Because of their compact form and their ability to hold a large amount of information, folded leaflets are a highly effective and popular marketing tool.

Folded leaflets usually come in a variety of formats, usually A4 or A5 sheets that fold into two, three or even more parts. Folding techniques help to organise information efficiently and create an attractive structure for the reader.

Depending on your content and design needs, you can choose from a number of popular folding options that give your leaflet a unique layout and functionality.

Most common leaflet folding methods:

• Two-part folding (one fold). The leaflet is folded in half to form four pages. It is a simple and effective way to present essential information, and is commonly used for smaller promotional content or presentations.
• Three-part folding (C-bending). The folding sheet is folded into three parts, with the sides folding inwards one after the other. This is one of the most popular folding methods, providing six pages suitable for presenting information in stages or categories.
• Z-folding. The paper is folded in a zigzag shape, where each section unfolds separately. This method of folding is suitable for clearly separating different blocks of information, giving each page more autonomy.
• Gate folding. The edges of the folder fold in the middle, like a door (gate). The main information is usually displayed in the middle, while the edges are used for introductory information. This is a great way to create a visually intriguing effect.
• Two parts (horizontal or vertical bending). The leaflet is folded in half horizontally or vertically to create two larger parts. This is a simple but visually strong folding method suitable for larger illustrations or information blocks.
• Folding a fan (multi-layered). The folder is folded in several small section folds, like a fan. This is a more complex folding method, providing ample space for information, but maintaining a compact appearance.

Each of these folding methods has its own advantages depending on the purpose of the leaflet. C and Z folds are popular for clearly separating different information, while Gate folds add visual intrigue.

Folded leaflets provide space for a large number of elements while maintaining a clear and organized structure.

It are usually printed on lightweight (150–250 gsm) glossy or matt paper to create a durable and aesthetic product. Different types of paper can be used, from plain, cost-effective papers to luxurious, decorative papers that add extra value.

Folded leaflets can use both single-sided and double-sided printing technologies, depending on the amount of information to be displayed. Leaflets are printed in both colour and black and white, but colour leaflets are more eye-catching and visually richer.
