Active vocabulary. A line is an element characterized by length and direction

A line is an element characterized by length and direction. Lines create contours and form, and are often used to convey a specific kind of feeling or point to an important feature in a design. Lines are also used to create perspective, and dominant directional lines are often adopted to create a sense of continuance in a composition. In addition, lines that are grouped together often create a sense of value, density of texture.

A line is a mark made by moving point and having psychological impact according to its direction, weight, and the variations in its direction and weight. It is an enormously useful and versatile graphic device that is made to function in both visual and verbal ways. It can function independently to suggest forms that can be recognized, even when the lines are limited in extent. Lines can be combined with other lines to create textures and patterns. The use of line in combination results in the development of form and value, which are other elements of design.

However, line is not always explicit. It can exist by implication, as the edge of forms. As young children we usually begin drawing landscapes by making outlines for earth, sky, and other objects. Gradually we learn that objects do not have such outlines and we let color changes define the edges of shapes, creating implicit lines. Thus we can speak of a horizon “line”, or the “lines” of a car or fashion silhouette, even though we know there is no literal line present.

Horizontal line suggests a feeling of rest or repose. Objects parallel to the earth are at rest in relation to gravity. Therefore compositions in which horizontal lines dominate tend to be quiet and restful in feeling. One of the hallmarks of Frank Lloyd Wright’s architectural style is its use of strong horizontal elements which stress the relationship of the structure to the land.

Vertical lines communicate a feeling of loftiness and spirituality. Erect lines seem to extend upwards beyond human reach, toward the sky. They often dominate public architecture, from cathedrals to corporate headquarters. Extended perpendicular lines suggest an overpowering grandeur, beyond ordinary human measure.

Diagonal lines suggest a feeling of movement or direction. Since objects in a diagonal position are unstable in relation to gravity, being neither vertical nor horizontal, they are either about to fall, or are already in motion, as is certainly the case for this group of dancers. In a two dimensional composition diagonal lines are also used to indicate depth, an illusion of perspective that pulls the viewer into the picture-creating an illusion of a space that one could move about within. Thus if a feeling of movement or speed is desired, or a feeling of activity, diagonal lines can be used.

Horizontal and vertical lines in combinationcommunicate stability and solidity. Rectilinear forms stay put in relation to gravity, and are not likely to tip over. This stability suggests permanence, reliability to the point of stodginess.

Curved lines do vary in meaning, however. Soft, shallow curves suggest comfort, safety, familiarity, relaxation. They recall the curves of the human body, and therefore have a pleasing, sensual quality.
