An Important Elements of Design – LINE
The line is one of the most basic elements of design. A line refers to the way that two points in space are connected or a series of points. Lines are used to connect two or more points and are being used still, starting even before from Ancient civilization. Some of the lines do not exist in nature, but they are indicative, such as the “horizon line”-the line between sky and earth.
Lines are classified as
- Horizontal lines
- Vertical lines
- Straight lines
- Curved lines
- Diagonal lines

Architects, interior designers, and any other designers start their design with the “LINE ” by drawing an outline, which is an important aspect and helps in creating fascinating architectural marvels.
Lines vary in thickness, weight can be
- Thick or thin
- Smooth or rough/jagged
- Flowing or tapering
- Bold or delicate
Line can have
- Dimension
- Movement
- Growth
- Character
- relies on length to -width ratio, contours, and degree of continuity.
- Emphasis
- Quality of Expression
Contour lines define the shape or form of the object.
Lines help in directing our eye movement towards a certain point.
Lines as Elements of Design
Horizontal Lines:
Stable, state of rest, plane, secure
Horizontal represents a plane upon which we stand, such as the ground, floor, or the earth. They seem to elongate a space widely drawing our eye movement from left to right or vice-versa. Thus the room appears wider. They represent stability and a state of rest.


The horizontal line of the wooden frame creates a wider space even though it is narrow. It creates a sense of stability. The different horizontal lines of the casework, furniture, and openings lower the vision and are contemporary.
Vertical Lines:
Solid, Movement, Direction
The use of vertical lines in interiors or exterior appear/creates an impression of being taller and heightened. It enhances and creates an impression of height. Vertical lines of a pillar draw our eyes from the bottom to the top and vice versa. They express the state of equilibrium with a force of gravity.

For example, in the above design of living space, the vertical lines of the stone wall of the fireplace draw our eye upwards, away from the visual place. Also, the vertical lines bring a feeling of height, adding emphasis to the living room.
Straight lines as Elements of Design
Orderly, Clear Direction, Secure, Movement
Straight lines are more orderly and clean with a clear direction and apparent path it takes. They can be horizontal or vertical or diagonal or can be a combination of them.


The visually sturdy horizontal and vertical lines form a rectangular shape, and the tall windows create a sense of stability and framework, feeling more rigid and secure.
The horizontal and vertical lines on the frame of the opening widen up the space and the horizontal line below the tv unit extends the space more than actually it is. The large openings create a visual sense of connectivity to the outdoors and the space between furniture creates a sense of movement.
Diagonal lines
Movement, direction, freedom, interest, angular stability
Diagonal lines can be seen rising or falling on any side. They are visually active and dynamic. Diagonal lines are commonly seen in sloped roofs in the house design and staircases, escalators, and customized furniture designs. They also add interest and energy.
Curved lines as Elements of Design
gentle movement, interest, softness, rhythm
Curved lines in design make the space more voluminous, and they express gentle and interesting movements.
