In AP Art History, contour lines are the drawn or implied lines that define the edges and forms of figures and objects in a composition. They are a core formal-analysis term you can use to describe how an artist makes shapes read clearly, from Japanese prints to Basquiat's graffiti-inflected canvases.
Contour lines are the lines, drawn or painted, that trace the edges of a figure or object and define its form. When you look at a work and your eye immediately separates the body from the background, contour lines are usually doing that work. A pure outline just marks where a shape stops; a contour line also follows the form, curving with a shoulder or a wave so the object reads as a thing with volume, not a flat cutout.
In the CED, this term lives in Topic 10.1, Materials, Processes, and Techniques in Global Contemporary Art (Unit 10). That placement makes sense because contemporary artists deliberately play with contour. Per MPT-1.A.35, contemporary art challenges hierarchies of materials, training, and style, and one visible way artists do that is by borrowing the bold, simplified contour lines of graffiti, comics, folk traditions, and printmaking instead of academic modeling. But the vocabulary itself is useful across all 10 units. Any time you do visual analysis, contour lines are part of your toolkit.
Contour lines support learning objective AP Art History 10.1.A, which asks you to explain how materials, processes, and techniques affect art and art making. Saying an artist "uses bold contour lines" is a technique claim, and the exam rewards you for connecting that technique to meaning. For example, thick, deliberately crude contours in a Basquiat painting reject academic polish and pull street art into the gallery, which is exactly the challenge to artistic hierarchies described in MPT-1.A.35. Beyond Unit 10, contour lines are bread-and-butter formal analysis language. SAQ prompts regularly ask you to describe visual characteristics of a work, and "contour lines" is a precise, credit-worthy term, far stronger than vague phrases like "the outlines look bold."

Jean-Michel Basquiat (Unit 10)
Basquiat is the go-to example of expressive contour lines in the contemporary period. His figures are built from raw, graffiti-derived outlines rather than smooth shading, and that choice is the argument. It puts street technique on equal footing with museum painting.
Ukiyo-e printmaking and Hokusai (Unit 8)
Japanese woodblock prints like Hokusai's Thirty-six Views of Mount Fuji series are basically masterclasses in contour. The carved block produces crisp, simplified outlines filled with flat color, so describing contour lines is one of the cleanest ways to analyze a print's technique.
Brushwork (Unit 10)
Brushwork and contour lines are partner terms in formal analysis. Brushwork describes how the paint is applied; contour lines describe how forms are defined. A loose, gestural brushstroke can blur contours, while a controlled stroke can sharpen them.
Faith Ringgold (Unit 10)
Ringgold's story quilts use simplified, outlined figures drawn from folk and narrative traditions. The clear contours make her figures legible across a crowded quilted composition, showing how a "simple" technique can carry a complex social message.
Contour lines show up as visual-analysis vocabulary, not as a term you'll be asked to define on its own. Multiple-choice attribution questions often hinge on recognizing a style by its line quality, like the crisp contours of a woodblock print versus the blurred edges of an oil painting. On free-response questions, the term earns you points when a prompt asks you to describe a work's visual characteristics or explain how technique creates meaning. The 2023 SAQ on Hokusai's Ejiri in Suruga Province, from the same Thirty-six Views of Mount Fuji series as the required Great Wave, is exactly this kind of task. Identifying the print's clear contour lines and connecting them to the woodblock process is the move that scores. The skill is always the same. Name the technique precisely, then say what it does for the work.
An outline only marks the outer boundary of a shape, like tracing around your hand. Contour lines include that boundary but also follow the form itself, curving along folds, muscles, or interior edges to suggest three-dimensional volume. On the exam, "contour lines" is the stronger analytical term because it implies the artist is describing form, not just drawing a flat silhouette.
Contour lines are the drawn or implied lines that define the edges and forms of figures and objects in a composition.
Unlike a flat outline, contour lines follow the form, so they can suggest volume and three-dimensionality even without shading.
In Unit 10, bold simplified contours borrowed from graffiti, comics, and folk art are a way contemporary artists challenge traditional hierarchies of style and training (MPT-1.A.35).
Contour lines are formal-analysis vocabulary you can use in any unit, especially for printmaking, where the carving process naturally produces crisp outlines.
On FRQs, name the technique and connect it to meaning, like saying Basquiat's raw contour lines bring street-art aesthetics into fine art.
Contour lines are the simplified lines that define the edges and forms of figures and objects in a composition. The term appears in Topic 10.1 of the CED, but it's useful formal-analysis vocabulary for any unit on the exam.
No. Topographic contour lines mark elevation in geography. In art history, contour lines are the lines an artist uses to define the edges and forms of figures and objects. The AP Art History exam only uses the art meaning.
An outline just traces the outer boundary of a shape, making it look flat. Contour lines follow the form itself, including interior edges and curves, so they can suggest volume. Use "contour lines" on the exam because it shows you understand how line builds form.
Yes, as analysis vocabulary. The 2023 SAQ on a Hokusai print from the Thirty-six Views of Mount Fuji series rewarded exactly this kind of observation, since woodblock printing produces crisp, simplified contours filled with flat color.
Jean-Michel Basquiat uses raw, graffiti-derived contours that reject academic polish, Faith Ringgold's story quilts feature clearly outlined folk-style figures, and Hokusai's woodblock prints in Unit 8 show how the carving process creates sharp contour lines.
