Shapes and Forms
Shapes
Shape: an area defined by line or color
A shape is two-dimensional and only has length and width. It is flat. A shape is an enclosed space. Wherever the ends of a continuous line meet, a shape is formed.
Recognizable shapes are called geometric or organic. Shapes that are difficult to identify are called abstract.

Geometric Shapes
Geometric shapes such as circles, rectangles, and triangles, are precise shapes that can be described using mathematical formulas. These shapes are frequently used to provide an organized quality to an art work.
Organic Shapes
Organic shapes or free form shapes are non uniform or irregular. They lack consistent edges and are more associated with objects in nature such as clouds, leaves, amoebas, and flowers.
See an example of organic shapes in Henri Matisse's Beasts of the Sea from 1950.
Positive and Negative Shapes
Shapes can be positive or negative.
- A positive shape is the one formed by the object itself.
- The one formed by the space around the object is the negative shape.
- The combination of positive and negative shapes gives people the image of what they see.
Forms
Forms have three dimensions — height, width, and depth.
The world we live in is made up almost entirely of forms. Artists have a strong understanding of form and how to create the illusion of form in drawings and paintings.

Geometric and Organic Forms
Just like shapes, forms can be either geometric or organic.
- Geometric forms have specific names associated with them and are typically man-made.
- Organic forms do not have specific names associated with them and are often associated with objects that occur naturally.
Geometric Forms
Geometric forms are precise and regular. They are often found in man-made things like buildings, machines, and school supplies. Artists use this type of form to make their art work look three-dimensional having or appearing to have length, width, and depth . Sculpture is the most common way to see form in art.
Organic Forms
Organic forms have a flowing, curving appearance. They are usually irregular or asymmetrical. Organic forms are associated with things from the natural world like plants, animals, and some fruits and vegetables. Artists use various techniques of shading to make organic shapes into organic forms.
