Shape and Form

Shape and form define objects in space. Shapes have two dimensions, height and width, and are usually defined by lines. Forms exist in three dimensions, with height, width, and depth.

Examples:


Shape has only height and width. Shape is usually, though not always, defined by line, which can provide its contour. In this image, circles dominate the composition.



Form has depth as well as width and height. Three-dimensional form is the basis of sculpture, furniture, motor vehicles, and decorative arts. Three-dimensional forms can be seen from more than one side.

Geometric shapes and forms include mathematical, named shapes such as squares, rectangles, circles, cubes, spheres, and cones. Geometric shapes and forms are often man-made. However, many natural forms also have geometric shapes.



Organic shapes and forms are typically irregular or asymmetrical. Organic shapes are often found in nature, but man-made shapes can also imitate organic forms.
