Discover all the ways geometric shapes can influence your home decor

Geometry is Interior Design’s Secret Weapon?

When it comes to interior design, people may not initially think of geometry, but it actually plays a crucial role in creating visually appealing spaces. The physical world is governed by rules of shape and form, from the most basic to the most elaborate. Furniture arrangements and rug patterns are all influenced by geometric principles. Even Gaspard Monge, a French mathematician, who was living 18-19 centuries, believed that geometry in design could inspire innovation and lead to new forms and applications. Geometry can be used to improve object functionality, bring order, and simplify environments. The geometric design is a powerful aesthetic technique that can have a significant impact, from creating shapes and lines to eliciting emotions and adding character to a room. In this article, we will explore the relationship between geometry and interior design, and how it can be used in innovative and creative ways to enhance our living spaces.

Types of geometric shapes

Geometry is an essential element of interior design, and understanding the different types of geometric shapes is crucial for designers to create visually appealing and functional spaces. The three basic forms for the study of structures, forms, modulation, and accumulation are the square, the circle, and the equilateral triangle, as Italian artist and designer Bruno Munari explained in his groundbreaking study, “The Square, The Circle & The Triangle”. However, there are also many other types of geometric shapes beyond these three basic forms, including regular and irregular shapes like parallelograms and cubes (in nature more complex shapes could be found but they are non-geometric). Contrary to common belief, geometric shapes in interior design don’t always consist of strong, cutting lines. Circles, ovals, and crescents are just as geometric as triangles, squares, and hexagons. So, if you want to add some geometric flair to your interior design, start with simple geometric patterns that feature any of these classic contenders.


The square's inherent geometry can be challenging to incorporate into the interior style, but it can be achieved through key pieces of furniture and accessories in the room. Side tables, mirrors, rugs, cushions, and even tissue boxes can all be designed with strong-sided squares or cubes in stature, creating a subtle yet effective geometric pattern in the space. These square-shaped elements express a sense of order and stability in the room, adding a touch of sophistication to any interior design. Whether used in isolation or in combination with other geometric shapes, squares are a powerful geometric shape that can create a strong impact on any apartment project.


Circles have always been a powerful symbol of unity, perfection, and infinity, making them a popular choice for interior design. From coffee tables and rugs to mirrors, circular shapes are widely used to create a sense of harmony and balance. Mixing circular shapes with bold geometric shapes like squares can add visual interest to a room, creating a dynamic interplay between soft and hard-lined shapes. Designers use circular shapes to infuse a room with a sense of fluidity and motion, adding dimension to an otherwise static space. Overall, adding circular shapes to an interior design plan can produce a unified, well-balanced appearance.


Triangles are one of the most inspiring forms in geometric design, having been utilized in architectural structures from the Renaissance to modern times. Their symmetrical and stable nature makes them a unique star of the show in interior design. Geometric patterns with triangles are dynamic and confident, but it's best not to mix too many types in the same space. To create a well-balanced design, it's best to stick with one or two types of triangles and use them sparingly. Incorporating the clean, minimalistic interpretation of triangles in your interior design can elevate the overall look and feel of your space.


The hexagon is an interesting and quite widespread shape in interior design, bringing a touch of excitement and modernity to any space. Created by the Ancient Greeks' love of geometric design, hexagonal forms can be found in everything from side tables to wall sconces to coasters. Their symmetrical shape adds structure and balance to a room while also providing a unique and eye-catching look. Use hexagons sparingly to create a subtle geometric pattern or incorporate them more boldly for a striking effect.

In The Golden Ratio

The golden ratio, a mathematical ratio of proportions that has been found aesthetically pleasing throughout history, is a perfect example of how geometry can be used in interior design. Many buildings, including the Parthenon and the Taj Mahal, were designed using this ratio. Similarly, modern structures such as the CN Tower in Toronto also follow this principle. In interior design, the golden ratio is often applied through the use of proportionate colors, furniture placement, and accent pieces. For instance, a space may utilize 60 percent neutral colors, 30 percent darkly colored furniture, and 10 percent warm-colored accents. This combination creates a harmonious balance that is both aesthetically pleasing and functional. When it comes to designing a space, geometry, and proportion are crucial factors to consider, and a golden ratio is a valuable tool that can guide designers in achieving an ideal look for any room.

In the Layouts of the Rooms

Geometry is an essential aspect when it comes to the layout of a room. The shapes, sizes, and placements of furniture, décor, and accessories play a vital role in achieving a balanced and visually appealing interior space. One of the fundamental elements of geometry in interior design is a symmetry which can be achieved through the right placement of furniture and decor pieces in a room. Other layouts, non-symmetrical, may be also necessary to make a room more functional, therefore designers consider the perspective of the room's purpose every time. For instance, in an office space, furniture placement can create natural synergies among staff, making them more productive, and thus, contributing to the company's profitability.

In Furniture

The furniture's look is significantly influenced by geometry. From the straight lines of a square dining table to the intricate curves of an upholstered armchair, there are many ways in which geometry influences furniture design. Shapes such as squares, rectangles, circles, and triangles are commonly used in furniture design as building blocks. For instance, a coffee table with square top and rectangular legs is an example of how geometry can be used in a simple yet effective way. Geometric patterns and motifs are also employed by furniture designers to enhance their creations. These patterns can be found in various elements such as the intricate carvings on a wooden cabinet or the repeating patterns on fabric upholstery. Moreover, the functioning of furniture is significantly influenced by geometry. A chair's comfort level can be determined by its angles and curves, and a table's size can affect how many people can assemble around it without feeling crowded.

In the Wall and Room Decor

Understanding how geometry affects a room's decor is important enough. Using geometric wallpaper or flooring is a popular way to bring patterns into a room. These patterns can create an illusion of height or add more space to a room. In order to provide a calming impression and a sense of order, it is crucial to pick modest geometric designs especially if you gonna cover a huge area. You can also incorporate interesting shapes in the smallest of details, such as hexagonal doorknobs or hexagonal patterned cushions, for example. Adding even a small geometric accent can make a big difference, and it is advised to echo one shape throughout a room.

In Patterns and Textures

Geometric shapes are a muse for many interior design options, from Art Deco to Contemporary styles. When it comes to creating a space with geometric shapes, it's essential to maintain balance. Using too many shapes or patterns can result in a cluttered and chaotic space, with no single shape or pattern receiving the attention it deserves. Instead, designers should focus on incorporating just a few shapes and spreading them across furniture and accessories in a way that works for their preferred style. Moreover, the use of color palettes and prints can help counteract the contemporary nature of squares, circles, and triangles, creating a more classic or country look, depending on your preferences. Also, it's important to consider the effect of architectural shapes already present in the room, such as floorboards, windows, staircases, and doorways, and integrate them into the design.
