What Are Lines in Art? [ Functions, Properties, & Types ]

The line is one of the fundamental elements of art, especially in drawing. Without this element, art simply wouldn't be possible.

What is the definition of a line?

Although the answer may seem obvious, there are many types of lines, each of which has properties that artists can use at their convenience. If you're just beginning your path as an artist, with this post you'll learn what a line is, its functions, characteristics, types, and a couple more things.

So if you want to start your journey on the right foot, continue reading this post to the end.

What are lines in art?

A line is a mark on a flat surface that indicates a boundary between two or more areas.

According to Euclid, a line is a multitude of points. The point is "something" that has no dimensions: neither height, width, nor depth. These dots are infinitely small, so they can only exist in the imagination of the artist. Now, a line is a succession of points. Or in other words, the union of two points in space.

But these points are so close to each other that, to the naked eye, they appear to form a continuous line.

The Function of Lines in Art

There are many uses for lines in art, including:

  • Outlining and defining contours: Lines help give artwork a sense of structure and order by delineating the outer edges of forms and shapes.
  • Diagonal or curving lines, for example, might be employed to convey a sense of motion in an artwork.
  • Lines are versatile and can be used to create a wide range of textures, such as cross-hatching and stippling, that can enrich and diversify an artwork.
  • Lines can be utilized to evoke a certain feeling or mood in a piece of artwork. In contrast to the serenity that smooth curves can evoke, the tension of sharp angles can do just the opposite.
  • Lines can be utilized to direct the eye of the observer toward a particular part of an artwork, thereby serving as a focal point.

In conclusion, lines are very adaptable artistic tools that may be utilized for a broad variety of purposes, from outlining and shading to conveying movement and emotion.

The Different Line Structures

Within the realm of visual arts, various line structures exist, such as:

Implied lines

Lines that are implied rather than drawn, such as those created by the arrangement of forms in an artwork. They can make anything feel like it's going somewhere or have some kind of motion to it.

Calligraphic lines

A sense of movement and grace can be conveyed by calligraphic lines, which are lines that flow from one point to another.

Gesture lines

Gesture lines are scribbled swiftly and loosely to represent a subject's vitality and motion.

Broken lines

Instead of a single, continuous line, broken lines consist of a sequence of shorter dashes or dots. In some cases, they can even impart a sense of vitality or motion.

Continuous lines

Drawing without raising the tool from the surface results in a continuous line, which can convey a sense of motion and continuity.

In conclusion, various line structures in visual art each have their own distinct qualities and effects. They're used for anything from outline and shading to conveying motion and feeling.

The Properties of Lines

In art, lines can be utilized for a variety of purposes thanks to their many distinct characteristics, such as:


The direction of a line can convey a sense of motion or progress in an artwork. The use of diagonal lines can convey a sense of motion or tension, whereas the use of vertical lines can evoke feelings of serenity or stability.


The quality of a line can be used to evoke a certain atmosphere or sense of texture. Using rough lines can evoke a sense of motion or excitement, while using smooth lines can evoke a peaceful mood.


For further depth and volume, try playing around with a line's value, or how much lighter or darker it is. A sense of depth or shadow can be achieved by using darker lines, while highlights or motion can be achieved by using lighter lines.


Feelings of surface or material can be conveyed by the varying thickness and smoothness of a line's texture. Create the illusion of depth and texture on a flat surface with techniques including cross-hatching, hatching, and stippling.


Adding visual interest and motion, contrast between lines can be used to great effect. A sense of contrast and motion can be achieved by utilizing lines of varying widths, directions, qualities, and values.


Lines that gradually fade into one another can give the impression of depth, volume, and motion. Direction, quality, and value can all be adjusted to create a gradual transition between two points.

Lines' direction, quality, value, texture, contrast, and gradation can be employed to generate a variety of effects in art, including movement, texture, depth, and volume. Artists rely on these qualities to infuse their creations with feeling and intrigue.

Why is the line one of the most important elements of art?

Due to its fundamental role in the development of form, shape, and structure in an artwork. A line is frequently cited as one of the most essential components of any creative endeavor.

It's versatile enough to be used for outlining, shading, and even animating. It has the potential to provide depth, resonance, and meaning to a work of art.

Lines can also be utilized to create the illusion of volume and depth on a two-dimensional surface. They can also be employed to give a piece of art a sense of motion, focus, and rhythm. Light and shade illusions, as well as the impression of texture and surface, rely heavily on the employment of lines.

In addition, lines can be employed to emphasize contrast and convey motion in an artwork. The artist can add visual appeal and a sense of motion to a work of art by blending different kinds of lines, such as thick and thin, smooth and rough, dark and bright.

What are the common types of lines in art?

While several types of lines are considered fundamental, it's important to note that these basic types can evolve into other types when artists add certain properties, such as length and thickness. Let's start with the basic types of lines.

Straight lines

A straight line is a succession of infinite points drawn in the same direction without a beginning or end. This means they're infinite, so you can never paint a completely straight line, only a small portion; you'll have to imagine the rest. On the other hand, there are two types of straight lines:

  • Vertical lines
Vertical lines are those whose trajectory is drawn in the direction from top to bottom or vice versa.
  • Horizontal lines

Horizontal lines are those that follow the direction of the horizon line, moving from right to left or vice versa. They are also perpendicular, maintaining an angle of 90 degrees to the vertical line.

Diagonal lines

Diagonal lines are straight lines that don't follow a vertical or horizontal direction. Also, they don't form right angles when intersecting these types of lines.

Zigzag lines

They're a series of diagonal lines joined together at their ends.

Curved lines

Curved lines are lines whose points don't follow the same direction, so they gradually change or bend.

In Conclusion

Being one of the basic elements of art, lines allow you to add all kinds of visual effects to an artwork. You can use lines to represent movement, feelings, rhythm, patterns, define shapes, etc.

Learning how the different types of lines can be combined with other elements will allow you to give your artwork greater structure and meaning.

The best thing you can do is start practicing now, trying as many options as possible. Remember that practice makes perfect.
