Dreiecksformat

Dreiecksformat is a German term used to describe a format, layout, or object whose primary shape is a triangle rather than the conventional rectangle. The designation is applied across different fields to indicate a deliberate triangular composition or physical form, and it does not refer to a single standardized specification.

In graphic design and publishing, Dreiecksformat can refer to layouts that use triangular arrangements of elements, cropping, or entire pages and covers shaped as triangles. Such formats are often chosen for visual impact, branding, or to fit unusual display contexts, and they may require specialized production and framing or mailing options.

In philately, Dreiecksformat is commonly used to describe postage stamps that are issued in triangular shapes as opposed to the standard rectangular format. Triangular stamps have appeared in various countries and eras, and they are typically noted in catalogs and collections under the category of triangular or Dreiecksformat issues. The term reflects both the geometry of the stamp and its deviation from the rectangular norm.

Dreiecksformat also appears in signage, packaging, and art, where triangular shapes are employed to attract attention, convey movement, or complement other design motifs. In architecture and sculpture, triangular panels or modules may follow a Dreiecksformat approach to create dynamic compositions.

Because the triangular form spans several disciplines, Dreiecksformat chiefly serves as a descriptive label that highlights geometry and intentional deviation from standard rectangular formats. See also: format (publishing), geometric design, triangular stamps.
