When outlining an interior design, the shapes you choose to fill each space are fundamental to the sense of balance and flow. As a leading Chicago interior design firm, we’re familiar with using the entire spectrum of geometric shapes, from gentle curves to more boxy mid-century modern forms. At the heart of every design is geometry, so even if your design includes organic forms or bold patterns, they often stem from fundamental geometric principles.

In this guide, we'll explore the significance of specific shapes and how various geometric elements can influence an interior space.

Circles

If you’re hoping to create serene living spaces without harsh edges, incorporating circular shapes is a must. Circular furniture like round tables and sofas not only look more inviting, but they take up less space than square or rectangular forms. For example, if you only have a small corner for a dining table, we recommend a circular table as it will allow more people to gather in a smaller area.

Squares

Squares are another popular choice for both large and smaller spaces. You’ll find them across tile patterns, furniture, and decor accessories. The sharp edges and right angles of this classically symmetrical shape lend a sense of order and stability to your surroundings. For example, a checkerboard pattern uses repeating squares to bring a sense of movement and energy to rugs, wallpaper, and upholstery.

Rectangles

With straight lines and sharp angles, rectangles are the most commonly seen shape in furniture design, windows, and flooring. They mimic the shape of most rooms, providing a traditional look that feels orderly. As a result, you'll often find rectangular furniture and home décor in functional spaces like the kitchen and home office.

Stripes

Stripes can change the perception of space, making a room seem either larger or more intimate depending on their orientation. We love using straight lines in wallpapers, fabrics, rugs, and more to introduce visual interest and direction into a space. Take a look at how we used sleek lines in this nursery to bring a modern twist to a classic stripe pattern.

Triangles

The triangular shape represents balance, providing a sense of harmony to any space. In fact, many designers follow the 'Triangle Principle,' which involves the careful placement of items to create a triangle shape. This principle helps focus attention toward the center of the triangle to highlight items like wall decor, a sofa, or a bathtub. Equilateral triangles can also be incorporated into art, textiles, upholstery, and light fixtures.

Herringbone Pattern

Many popular patterns blend interesting shapes, but one of our favorites is the subtle geometric pattern of herringbone. This pattern introduces a sophisticated texture and movement to interiors. Often used in flooring, backsplashes, and upholstery, herringbone adds a touch of elegance and an old-world feel.

Remember thinking you had left geometry behind in school? Not so! While the use of geometry is crucial in interior design, think of it as a fun and practical real-world application. By focusing on the science of shapes, you can create a modern, cohesive interior design that feels elevated. Using the existing architectural elements of your home combined with the purpose of the room and overall design aesthetic, you can create a space that has the right balance of style and functionality.

Our interior designers love taking geometric forms and making a bold focal point in a dining room, bedroom, or living room. For more inspiration on how to create a geometric design, view our latest design projects here!
