Grundformerna

Grundformerna, meaning "the basic shapes" in Swedish, is a concept used in geometry, art education and graphic design to refer to the simplest forms that serve as the building blocks for more complex figures. The most commonly cited Grundformer are the circle, the square, and the triangle. These shapes are valued for their distinct visual properties: circle for curved symmetry, square for equal sides and right angles, triangle for its three-sided polygon and stability. In teaching, students learn about area, perimeter, and transformation by starting with these shapes. The idea originates from early 20th-century design and pedagogy that emphasized reduction to essential forms as a method of analysis and composition.

In practice, Grundformerna are used to analyze logos, layouts and illustrations, and to construct more complex figures by combining these basic shapes or applying geometric operations such as scaling, rotation and union. In design pedagogy, simplified shapes help students consider balance, contrast and unity without distraction from details.

In a three-dimensional context, equivalents often discussed are the basic solids—the sphere, the cube, the cone and the pyramid—used to teach volume, surface area and spatial reasoning. While not universal, the term Grundformerna is commonly linked to both 2D and 3D basics in Swedish educational materials and design textbooks.
