Art Deco Interior Design
Geometric Shapes in Art Deco Interiors: A Design Staple
Art Deco interiors lean on a small set of geometric shapes. Chevrons, zigzags, sunbursts, stepped forms and fans repeat across floors, walls, ceilings, metalwork and furniture, and that repetition is what gives a room its symmetry and its slightly mechanical sense of luxury.
Paris designers were using these forms long before the style had a name. The Theatre des Champs-Elysees opened in 1913, 12 years before the 1925 exposition that gave Art Deco its title (Dezeen, 2025).
Hotel lobbies and theatres from the 1920s and 1930s keep repeating the same small vocabulary, and so do the apartments of the period. Modern rooms borrow it in rugs and mirrors, and sometimes parquet.
Which Geometric Shapes Define Art Deco Interiors?
Most of the style comes down to chevrons and zigzags, sunbursts, stepped forms, fans, and circles along with their angular relatives, the octagon and hexagon.
Everything on that list repeats or radiates from a point. That is what separates Art Deco geometry from one-off ornament.
Chevron and zigzag
Chevrons are inverted Vs stacked in rows, and they read as direction and lift. You see them mostly in parquet and rugs.
The zigzag is the same idea stretched into a single line that bends back and forth, used as a border, an inlay or a relief. It ties back to the lightning-flash motifs of the period.
Both turn up on rugs and headboards, plus hardwood inlay, and this guide to how chevrons are used in Art Deco rooms shows the placements in detail.
Sunburst
A sunburst puts a full or half circle at the center and sends straight rays outward, so it pulls a wall or a ceiling into a single focal point.
Mirrors with radiating rays are the usual version, hung above a console or a fireplace. Wall art and wallpaper repeats borrow the shape too, and so do pendant and wall lights with rayed shades.
The fan motif works the same way across a half circle only. A separate piece on sunburst motifs in Art Deco design goes further.
Stepped forms
Stepped forms are receding tiers, each one smaller than the one below, and a ziggurat is the full pyramid version of the idea.
They get used on cornices and ceiling coffers, but also on headboards, mirror frames and lamp bases.
Stepping adds depth without adding color, which suits rooms with a narrow palette.
Fan and scallop motifs
Fans spread rays across a half circle from one base point. Repeat them in rows and they overlap into a scallop pattern.
The motif shows up in wallpaper and tilework, and sometimes in inlaid panels, usually at a smaller scale than a sunburst. It suits surfaces that need rhythm more than a focal point.
Circles, octagons and hexagons
Circles appear as round mirrors and tabletops, and lamp bases too, and they break up the straight lines around them. Octagons sit in floor medallions and tile centers. Hexagons mostly repeat in tile and inlay.
Terrazzo contractors can cut divider strips by waterjet to form medallions like these (National Terrazzo and Mosaic Association).
Where Did Art Deco Geometry Come From?
Cubism and Egyptian Revival motifs fed in from one side, and the setback skyscrapers of New York from another. The 1925 Paris exposition then gave the style its name.
Influences before 1925
Picasso and Braque created Cubism in Paris from about 1907 to 1914, and many French designers borrowed its abstracted shapes for decoration (Metropolitan Museum of Art).
Egypt came later. Howard Carter’s team found the steps to Tutankhamun’s tomb on 4 November 1922 (Historic England, 2022), and the Met describes the Egyptian motifs that followed as an integral part of Art Deco’s visual language.
The 1925 exposition
The Exposition internationale des arts decoratifs et industriels modernes opened in Paris in April 1925 and ran into the autumn (V&A).
The usual story says the exposition launched the style and gave it its name (V&A). That’s only half the picture. The shapes were in use years earlier, and the Theatre des Champs-Elysees, often called the first Art Deco building in Paris, opened in 1913 (Dezeen, 2025).
So both accounts hold up. The name comes from 1925, the geometry comes from before it, and the V&A adds that the term “Art Deco” itself was coined in the 1960s.
Skyscraper setbacks
New York’s 1916 Zoning Resolution was the first citywide zoning law in the United States, according to the Landmarks Preservation Commission’s 2024 Heckscher Building report.
The Museum of the City of New York credits the law with the iconic setback skyscraper (2016). That outline is the source of the stepped massing that defines Art Deco architecture, which interior designers later scaled down into cornices and furniture.
The Chrysler Building and Empire State Building, the two tallest in 1931, took their shapes from the same law (Superstructures, 2020).
The shift toward Streamline Moderne
Angular ornament thinned out in the late 1930s.
Streamline Moderne favored long curves and horizontal bands over zigzags and chevrons, so a room built from 1925 forms and one built from late-1930s forms call for different shapes.
Which Shape Belongs on Which Surface?
Floors do best with chevrons and checks, plus the occasional medallion, while walls suit stepped panels and fans. Ceilings want sunbursts and tiered cornices. Metalwork carries grids and zigzags, and furniture gets stepped bases and circular tops.
Floors
Terrazzo made geometric floors practical in the 1920s. The National Terrazzo and Mosaic Association says the American industry took off when architects discovered its design potential for Art Deco, helped by divider strips and the electric grinding machine.
In terrazzo that means chevron bands and borders, plus medallions, all set out with divider strips. Marble goes black-and-white checks or large-scale chevrons. Wood goes herringbone or chevron parquet.
For pattern ideas in more depth, see this overview of inlaid floor patterns from Art Deco interiors.
Walls
Stepped panels work well on walls, as do fan or sunburst wallpaper repeats. Bands of chevron or zigzag are the simpler option.
In 1925 Jean Dunand made lacquered wall panels that enclosed a whole room for the first time (Phillips).
Ceilings
Ceilings take radiating and tiered shapes. A sunburst medallion anchors the center, and stepped coffers or cornices frame the edges.
The profiles of those cornices are covered in this look at the decorative moldings used in Art Deco homes.
Metalwork and doors
Edgar Brandt’s L’Oasis, an iron and brass five-panel screen from about 1924 (Christie’s), was among the pieces he showed at the 1925 exposition (Joan Kahr, 2010). His grilles and gates mixed Egyptian and Greek motifs with stylized plants, animals and machine-inspired geometric forms.
Elevator doors got the same attention. The Chrysler Building’s cabs and doors combine unusual and variegated woods (Landmarks Preservation Commission, 1978).
Metal carries the sharpest lines in the room, so grids and zigzags sit best here.
Furniture and lighting
Ruhlmann’s “Spider” table sets a circular inlay of ivory dots on a radiating veneer pattern, on a double-tiered top (Galerie Marcilhac). The V&A has held an example, designed in 1918-20 and made in 1929, since 1967 (V&A).
Smaller pieces repeat the logic. Side tables take circular, stepped or angular bases, and lamps take geometric shades in polished metal and frosted glass.
Which Materials Hold Geometric Patterns Best?
Inlaid veneer, terrazzo, polished metal and lacquer each hold a different kind of geometry, and each has a documented weak point.
| Material | Pros | Cons |
|---|---|---|
| Inlaid veneer | Fine radial and diamond detail | Chips and lifts; rare timber |
| Terrazzo | Durable floor; shapes set by strips | Needs trained installers |
| Brass and iron | Sharp edges that hold fine lines | Tarnish; lacquer wears |
| Lacquer | Deep glossy ground for incised or inlaid lines | Specialist technique |
Veneer is the fussiest of the lot. The Brooklyn Museum’s record for four Ruhlmann side chairs (ca. 1923, Macassar ebony veneer with ivory inlay) notes that much of the veneer had chipped off and was missing, and the frames were restored in Paris after purchase.
The timber itself is under pressure, since the IUCN Red List classes Diospyros celebica as Vulnerable (1998 assessment). For judging a piece, the list of what defines Art Deco furniture is a useful companion.
Cement terrazzo still calls for divider strips every 4 by 4 feet to counter movement and shrinkage cracking, according to the National Terrazzo and Mosaic Association. Epoxy terrazzo can be poured without strips at all.
Brass needs upkeep. U.S. General Services Administration guidance says unfinished brass must be polished frequently to keep its luster, and every polishing removes some brass. Lacquered brass usually lasts about 10 years without frequent polishing.
The Chrysler Building lobby, an interior landmark since 1978, pairs red Moroccan marble with Nirosta steel (Landmarks Preservation Commission).
Eileen Gray and Jean Dunand learned lacquer from the same teacher, Seizo Sugawara (Phillips). Dunand began working with eggshell lacquer around 1925, and later used it on furniture, screens and large wall panels (Phillips).
How Symmetry, Repetition and Color Hold the Shapes Together
Mirror the layout around a central axis, repeat each motif at a steady interval, and set the shapes in hard contrast.
Axis, repetition and scale
The Empire State Building’s Fifth Avenue lobby runs as a long, narrow hall toward an aluminum image of the tower with a radiating sun behind it (Landmarks Preservation Commission, 1981).
There’s one axis and one focal image, and everything else stays subordinate to them.
At home, that means putting the strongest shape on the centerline of the wall or room, whether it’s a sunburst mirror, a medallion or a stepped console. Repeat each motif at an even interval so the eye reads a pattern and not scattered ornament.
Scale matters too. One chevron band reads as an accent, while a room-wide repeat reads as pattern.
Planner5d notes that symmetry is why Art Deco rooms feel formal even when the furniture is rounded. The balance side of this is covered in how symmetry works in interior design.
Color pairing
Designers and paint makers don’t quite agree here. Studio Jane Designs, quoted by Livingetc, names three dominant tones, black, brushed gold and ivory or cream, with black used for definition.
Earthborn’s 1919 to 1939 palette goes another way. It lists dusty pink, terracotta, sage green, teal, aqua, navy, periwinkle and charcoal, with no black or gold swatch.
Both lists circulate as the Art Deco palette. In practice the constant is tonal separation between neighboring bands of a chevron or zigzag, whatever the hues.
A longer list of the colors that define Art Deco rooms sits in its own guide.
Which Historic Interiors Show the Shapes in Place?
Radio City Music Hall, Eltham Palace and the Art Deco buildings of Miami Beach all have well-recorded detail.
| Interior | Built | Shapes on record | Materials or finish on record |
|---|---|---|---|
| Radio City Music Hall, New York | 1932 | Whimsical modern patterns, patterned carpets | Aluminum, cork, Bakelite, tubular steel |
| Eltham Palace, London | 1933 to 1936 | Glazed dome, marquetry panels | Blackbean veneer |
| Miami Beach Art Deco buildings | 1930s | Curved edges and corners, round porthole windows | Neon lighting, pastel paint |
Donald Deskey’s 1932 commission for Radio City Music Hall was the first public commission to feature unlikely materials such as cork, aluminum and steel, according to Cooper Hewitt (2012). Aluminum wallcoverings and furniture of Bakelite and tubular steel followed. Deskey called his own style “modern rococo”, a label that sits oddly beside the standard Art Deco tag.
The interior became a New York City landmark in March 1978, yet most, if not all, of Deskey’s modern interiors with complete furniture no longer exist.
The Courtaulds built Eltham Palace between 1933 and 1936 (Dezeen, 2025), and over 600 plans by the architects Seely and Paget survive in the Historic England Archive, according to English Heritage.
Country Life photographs from 1933 to 1937 record the main rooms in detail.
The Miami Beach district reached the National Register of Historic Places on 14 May 1979, with over 800 buildings counted as contributing (City of Miami Beach, 2021).
Its 1930s buildings are known for curved edges, porthole windows and pastel hues, which backs the pastel side of the palette split.
The Miami Design Preservation League points out that national listing brings tax incentives but no protection from demolition, which only local designation provides.
For more buildings with documented geometry, this roundup of other well-known Art Deco buildings is a good next stop.
How to Use Art Deco Shapes in a Modern Room
Commit to one shape on one surface, then repeat it once at a smaller scale.
- Pick one lead shape (chevron, sunburst or stepped form) and drop the rest.
- Put it on the surface that gets the most attention: a rug, a mirror or an accent wall.
- Size the pattern to the room before buying.
- Add one material that carries the shape, such as brass, lacquer, marble or veneer.
- Repeat the shape once at a smaller scale, on a lamp or a cushion.
- Hold the palette to two or three colors plus one metal.
Step 3 is where most rooms go wrong. Measuring the seating group with a rug size calculator before you order saves a chevron rug that ends up too small.
Living room
A monochrome room can carry a single bold Art Deco piece without turning into a period set, according to Homeworld Design.
A sunburst or geometric mirror works as the focal point, and a chevron or geometric rug can go under the seating.
Pick one first. Add the second only after the room settles.
Bedroom
Designer Zahir Abdul Latheef suggests black-and-white zigzag cushions or chair upholstery when the goal is only a light touch (Gulf News, 2022).
For full commitment, a headboard with a geometric pattern or tufted velvet does the job (Chairish). Keep the wall behind it plain so the headboard carries the shape.
Entry and hallway
On the floor, black-and-white checks work, or parquet in two matched wood stains laid in herringbone (Gulf News, 2022). On the wall, one geometric mirror on the centerline is enough.
Narrow halls suit the repeat-and-mirror logic well, and these Art Deco hallway decor ideas show how it plays out in tight spaces.
When Geometric Art Deco Shapes Stop Working
They stop working when scale, count or setting breaks the repetition the style depends on.
Small rooms go first. A motif wider than the wall it sits on reads as noise, so drop to one accent.
Stacking motifs causes trouble too. Chevron, sunburst and fan in one view compete, and symmetry is what keeps several shapes from looking cluttered (St. Louis Home magazine). I’d stop at two shapes in any single room.
Quiet shells are another case, since contemporary designers tone down both palette and pattern when mixing Art Deco with modern neutrals (Homeworld Design). And heritage fabric, meaning original geometric glazing, carries comfort costs.
A motif’s width against its wall is a question of scale and proportion in a room, and no pattern rescues a wrong ratio.
At the Hoover Building in Perivale, the single-glazed steel Crittall windows did little for noise or heat retention, and listing meant they had to stay. Selectaglaze fitted over a hundred secondary glazing units there between 1996 and 1999.
Clean, minimal rooms, as in a minimalist living room design, take one Art Deco piece, not three.
Common Questions About Geometric Shapes in Art Deco Interiors
How do Art Deco shapes differ from Art Nouveau shapes?
Art Deco replaced flowing, plant-based curves with geometric, machine-age forms, symmetry and stepped silhouettes.
Interiors in the Art Nouveau style came first and favored organic lines. A whiplash curve points to Nouveau, a repeated chevron to Deco.
Is Art Deco geometry the same as Bauhaus geometry?
No. Both reduce objects to basic shapes, but Art Deco uses them as rich ornament in lacquer, marble, brass and similar materials, while Bauhaus uses them to serve function with little decoration.
Is herringbone the same as chevron in flooring?
No. Chevron planks are cut at an angle so their ends meet in a continuous V, while herringbone uses rectangular blocks laid in an offset zigzag.
Both read as Art Deco, but chevron gives the cleaner arrow line.
Can Art Deco shapes work in a rental where walls and floors cannot change?
Yes. Rugs, mirrors, cushions and lamps carry the shapes without touching the structure.
A sunburst mirror or a chevron rug in an otherwise monochrome room delivers the look on its own.
How to Spot an Art Deco Reproduction
Geometric shapes in Art Deco interiors copy easily, so authenticity rests on provenance and maker’s marks, plus hidden construction, not on the pattern itself.
A reproduction in correct materials is a fair purchase, and the problem starts only when a copy is priced as an original (Vinterior).
Check the maker’s stamp and paperwork first, then the joinery and veneer on hidden faces. Hardware and finish wear come last.
Provenance goes first because ownership records and the Ruhlmann archive, held at the Musee des Annees 30 in Boulogne-Billancourt, are the external checks a buyer can trace (Galerie Marcilhac).
Machine-perfect veneer is a red flag (Vinterior), yet period veneer chips, as the Brooklyn Museum’s Ruhlmann chairs from about 1923 show. A flawless surface on a claimed 1920s piece needs an explanation.
A documented original costs more than an honest reproduction, and the paperwork is part of what the buyer pays for.
