Definition: Paper folding
Paper folding is the process of bending a printed sheet into a specific shape or layout to serve a functional or design purpose. It is commonly used in commercial printing to create brochures, mailers, invitations, menus, and other marketing materials.
This type of folding is different from decorative or artistic paper folding, such as origami (折り紙), the traditional Japanese art of folding paper into intricate shapes without cutting or gluing.
In printing, folding helps organize content, improve presentation, and guide the reader’s attention, making it an essential element in effective print design.

Common types
There are many ways to fold paper, each with its own purpose and effect. Some folds are simple and classic, while others are more complex and eye-catching. The choice of fold depends on the format, content, and desired user experience. Below are the most commonly used fold types in printing.
The C fold, also called letter fold, divides the paper into three equal panels, folded inward so one panel tucks inside. Viewed from the side, it resembles the letter “C.” It’s commonly used for brochures and letters that fit into standard envelopes.
The tri fold is similar to the C fold but doesn’t always require equal panel widths. It divides the paper into three sections, with two folds creating a compact layout. This fold is common for brochures and menus, offering a step-by-step reading flow and convenient handling.
A gate fold features two end panels that fold inward to meet in the center without overlapping, like a pair of gates. It opens up to reveal a larger central panel, making it ideal for impactful designs, invitations, or promotional materials that benefit from a dramatic reveal.
The accordion fold creates a zig-zag shape with multiple parallel folds that alternate direction. Each panel folds in the opposite direction of the previous one, making it easy to expand and collapse. It’s well-suited for timelines, step-by-step guides, and visual storytelling.
Also known as the cross fold, the French fold involves folding a sheet in half vertically and then again horizontally. This creates four panels of equal size. It’s commonly used for greeting cards, event programs, or inserts that require compact delivery and unfolding.
In a double parallel fold, the sheet is first folded in half, then folded again in the same direction, creating four panels. This fold is useful for longer content, such as instructional brochures or manuals, as it provides a clear, linear reading path.
A roll fold involves folding each panel inward over the next, rolling in from one end to the other. This creates a compact and layered format, often used for step-by-step instructions, product features, or multi-part promotions that reveal content gradually.
The half fold, or single fold, is the most basic folding method. The sheet is simply folded once down the center, creating two equal panels. It’s often used for greeting cards, booklets, or simple programs where minimal structure is needed.

FAQs
Paper folding in printing refers to the process of bending printed sheets into specific formats, like brochures or mailers, to enhance usability and presentation.
Yes, it’s also called “document folding” or simply “folding” in the printing industry. In a different context, especially the artistic folding of paper, it’s known as origami (折り紙) in Japanese.
Theoretically, yes. Due to exponential growth in thickness with each fold. But practically, it’s impossible with regular paper.
With standard paper and human strength, it’s very hard. However, with large, thin sheets and tools, people have folded paper more than 8 times.
Each fold doubles the thickness and reduces the foldable area, making it increasingly harder to fold further.
