What Are Wall Paintings Called? | The Formal Term

Wall paintings are formally called murals, a term that describes large-scale graphic artwork painted directly onto a wall, ceiling, or other permanent surface.

Walk past a massive, story-filled scene painted across the side of a building, and you’re looking at a mural. That’s the specific artistic name for it. While “wall painting” describes the act, mural is the established term for a piece that’s integrated into the architecture itself—not hung on it, but part of it. The term comes from the Latin murus (wall) and gained traction as a Spanish adjective before becoming the noun we use today. Britannica confirms the straightforward rule: any wall painting may be called a mural, but the name carries weight for works designed with scale, narrative, and architectural intent.

What Exactly Defines a Mural?

A mural is any piece of graphic artwork applied directly to a wall, ceiling, or other permanent substrate. Wikipedia’s definition captures the full scope: murals are painted or applied directly rather than created on a separate canvas and hung. What separates a mural from a decorative accent wall is integration—the mural becomes part of the building’s space, modifying the room or exterior rather than merely coating it. Modern murals can be painted off-site on panels or mural cloth and installed at a final destination, so being created in situ isn’t a strict requirement. The core distinction remains permanence and architectural connection.

Mural vs. Wall Painting: What’s the Difference?

The difference between a mural and a general wall painting comes down to scale, intent, and integration with the space. Not everything brushed onto a wall earns the mural label.

The Main Categories: Fresco, Graffiti, and Other Mural Techniques

Mural is an umbrella term covering several distinct techniques. The most famous is the fresco—Italian for “fresh”—which requires pigment applied to wet lime plaster so the color merges permanently with the wall. True fresco must be painted while the plaster is still damp; if the plaster dries first, the technique fails and becomes fresco-secco (dry fresco). Other mural methods include encaustic (hot wax), tempera (egg-based pigment), oil painting on canvas that’s later fixed to the wall (marouflage), liquid silicate for exterior durability, and modern fired porcelain enamel for weather resistance. Graffiti is also a mural technique, typically using spray paint on outdoor walls.

How Do Artists Actually Paint a Mural?

Creating a mural begins with surface preparation—the wall must be clean, primed, and in some cases, freshly plastered for a true fresco. Artists transfer their designs using grid systems or projections, then build the image in layers. Traditional fresco painting demands speed: once the plaster is laid, the painter has only that day’s work session before it cures. Modern murals often start with a base coat and progress through blocking, detailing, and sealing. Water-based acrylic is a common choice for its fast drying time and sunlight resistance, while oil-based paints dry slower and offer deeper translucency for rich shadow effects.

Common Misconceptions About Wall Painting Terminology

Several mistakes pop up regularly when people talk about wall paintings. The biggest is calling any wall painting a fresco—true fresco requires wet lime plaster, and the word only applies to that specific chemical bond. Another is assuming every painted wall is a mural. Simple patterns, single-color accent walls, functional signs, and small decorative diagrams don’t qualify; a mural needs scale and an integrated artistic purpose. And a large painting on canvas is not automatically a mural—it’s a large painting. The crucial element is that the artwork modifies the space itself rather than simply covering it.

Why the Term “Mural” Matters Beyond Art

The name carries weight in real estate, city planning, and community identity. Murals are often commissioned by city councils, schools, and businesses as public-facing investments that engage viewers and commemorate local culture. Dr. Atl’s 1906 manifesto in Mexico—calling for “monumental public art” named pintura mural—established murals as tools for social storytelling. Today, a designated mural can affect property values, cultural tourism, and neighborhood pride in ways a simple wall painting cannot. The term signals that the work was deliberate, permanent, and built for the space, not just decoration.

Real-World Examples: Murals You Already Know

The Sistine Chapel ceiling is perhaps the world’s most famous mural—Michelangelo’s fresco technique merged pigment with wet plaster to create a scene inseparable from the architecture itself. Mexican muralists like Diego Rivera used the form to tell national stories across public buildings. Modern street artists like Banksy create murals that blend graffiti technique with political messages, often targeting exterior walls of commercial buildings. Each example shares the same foundation: artwork that the wall itself becomes, rather than artwork that simply hangs on it. If you’re considering a mural for your own space, you’ll find options ranging from professional fresco to canvas panels installed with the marouflage method—and a solid guide to the best artistic wall painting products can help you compare styles and techniques for a residential project.

Mural Techniques at a Glance

The formal name for wall paintings is mural, whether the piece uses Renaissance fresco or modern spray paint. Understanding the distinction between a mural and a simple wall painting comes down to three questions: Is it large? Does it carry a narrative or message? Is it built for the space? If the answer to all three is yes, that wall painting has earned its mural status.
