Harnessing the Principle of Similarity: Interior Design Principles at Work
The symphony of an elegantly designed interior space often strikes a chord within us, capturing our hearts and minds as we appreciate the balance, rhythm, and harmony it exudes. But what drives this captivating harmony? The answer lies within the fabric of the interior design discipline itself: the subtle yet potent, “Principle of Similarity.”
The Principle of Similarity, grounded in the world of Gestalt psychology, states that it’s human nature to group similar elements together based on visual perceptions. As interior designers, we wield this principle like a conductor’s baton, orchestrating a perfect symphony of design elements. This harmony of color, pattern, scale, rhythm, natural light, and textures creates an inviting atmosphere that quietly whispers: “You belong here.”
The incorporation of similarity in design isn’t exclusive to the field of interior design, though. It’s a universal language, shaping the realms of product design, architecture, and even UX design. All these disciplines understand that the human brain intuitively searches for patterns, relationships, and symmetries. And when it finds them, it’s like the brain is singing along with a beloved, familiar song.
Consider the principles of closure and continuation, two siblings of the Principle of Similarity. They inform everything from the layout of a user-friendly website to the architectural blueprints of a visually pleasing building. In the interior design world, we use these principles to create spatial flow and a sense of closure, drawing upon our understanding of the human brain’s desire for continuity and completion.

Renowned researcher and author Colin Ellard, in his book “Places of the Heart: The Psychogeography of Everyday Life,” eloquently explores the profound effects our surroundings have on our emotions, behavior, and even health. This evidence-based approach to design underpins the importance of harnessing design principles for maximum positive impact. Without further ado, here are 15 ways to apply Gestalt’s principle of similarity in interior design:
- Color Palette: Utilize a monochromatic or analogous color scheme, using varying shades of a color, or colors that are close to each other on the color wheel, throughout your space. This approach can create a harmonious and aesthetically pleasing atmosphere.
- Patterns: Patterns are a compelling way to introduce similarity. Consider incorporating the same pattern or motif in different aspects of the room, such as upholstery, rugs, or even wall art. This creates a visual link between these elements and establishes a theme.
- Texture: Texture has a significant impact on the feel of a room. By using similar textures across different elements such as curtains, cushions, and carpets, you can create a sense of unity and sophistication. This could mean choosing textiles that have a similar weave or feel to them.
- Furniture Style: By selecting furniture pieces that share the same design style or period, you create a sense of harmony and cohesion in the room. For instance, choosing all mid-century modern pieces will establish a distinct, coordinated look.
- Scale: Scale is all about maintaining balanced proportions between furniture and architectural elements. By keeping a consistent scale—for instance, not pairing a large, overstuffed sofa with a delicate, petite coffee table—you ensure the room feels balanced and cohesive.
- Shapes and Forms: Repeating similar shapes and forms in your furniture and décor items can create a visual rhythm that draws the eye across the room. For example, circular forms could be echoed in everything from your coffee table, to lamps, to decorative bowls.
- Material: Using the same material in various elements of the room can tie the design together. This could be as simple as matching the wood of your furniture with the wood of your floors or as subtle as using metal accents that match the metal in your light fixtures.
- Artwork: Artwork is another excellent opportunity to utilize the principle of similarity. By selecting pieces that share a common theme, style, or color palette, you create a visually compelling narrative that ties the room together.
- Light Fixtures: Lighting not only serves a functional purpose but can also be a unifying design element. By choosing light fixtures that have a similar style or finish, you can contribute to the overall cohesion of the room’s design.
- Flooring: Using a consistent flooring type or color throughout your home can help different areas flow into each other, creating a sense of continuity and similarity that is pleasing to the eye.
- Architectural Elements: If your home has distinct architectural features like arches, columns, or exposed beams, repeating these throughout the space can help tie different rooms or areas together and create a sense of unity and harmony.
- Accessories: Even small details like accessories can play a significant role in creating similarity. For instance, repeating motifs or materials in items like cushions, vases, or picture frames can subtly tie the room together.
- Window Treatments: Window treatments are often a large visual element in a room, so keeping these consistent in style, fabric, or color can significantly enhance the sense of visual similarity.
- Wall Decor: Similar wall decor elements, such as a series of framed photos or mirrors with the same frames, can create a visual rhythm and consistency that adds to the sense of harmony in a space.
- Room Themes: By choosing a theme and using it in different rooms, you can create a harmonious and unified interior design. This can be achieved by using similar colors, materials, or styles that represent the theme throughout all rooms. For instance, a coastal theme might include light colors, natural materials, and accessories like shells or maritime artwork.
In my own journey as an interior designer, I have personally experienced the transformative power of these principles. I recall working on a project that had a particular challenge: a long, narrow living room that felt both cramped and disjointed. Drawing upon the Principle of Similarity, I chose a series of similar shapes, repeating them in the furniture and decor, creating a sense of unity and coherence. In the end, this “awkward” space blossomed into a cozy, inviting sanctuary for the homeowners.
Embracing similarity, however, doesn’t mean eschewing diversity. In fact, as we navigate through the exciting journey of design, we discover that the power of similarity is often amplified by its clever use with other principles. The balance between symmetry and asymmetry, the dance of continuity and contrast, and the rhythm of repetition and variety—all contribute to a vibrant symphony of design.
The interior design landscape is as varied as it is exciting. From creating pet-friendly homes that consider the comfort of our furry friends, to leveraging the psychology of colors for a restful sleep or an inspiring study room, the possibilities are boundless. It’s a joyous exploration, where we learn, adapt, and create, turning every space into a unique masterpiece.
A deeper dive into the Principle of Similarity, paired with a mastery of other design principles, brings out the designer in each of us. It’s a journey that beckons, promising not just aesthetic beauty, but spaces that resonate with our deepest emotions, subtly whispering in the language of design, making us feel understood, embraced, and truly at home.
As we immerse ourselves in this symphony, let us celebrate the power of similarity—a design principle that serves as the universal language of coherence, rhythm, and harmony. And in doing so, we master the art of crafting spaces that truly sing to the heart.
Final Thoughts
Designing a space that feels harmonious, coherent, and aesthetically pleasing can sometimes feel like a puzzle. But, with the principle of similarity in interior design, we, as designers, can skillfully craft environments that are a symphony of unity and order. This principle, which states that it is human nature to group similar elements together, is based on our visual perceptions. It’s the law of similarity at work, a fascinating principle that’s deeply rooted in the human brain’s architecture and processes.
The principle of similarity doesn’t exist in isolation. Instead, it’s one cog in the wheel of Gestalt principles, such as the principle of closure and the principle of continuity. These principles weave together to form the tapestry of design principles that guide our work as interior designers. This isn’t merely theoretical—it’s all about practicality, aesthetics, and psychology rolled into one.
As an interior designer, I’ve seen firsthand how deploying the principle of similarity can create spaces that inspire joy, comfort, and continuity. From a living room filled with analogous colors to a bedroom defined by repeating patterns, the joy of creating such harmonious spaces is truly unparalleled.
This principle is not just confined to our field of interior design. You’ll see it being applied by UX designers, product designers, and those involved in architecture and art. They all use the principle of similarity to create products, user experiences, and structures that are intuitive, harmonious, and aesthetically pleasing. This highlights the universality of these principles—they’re not just confined to our field but form the cornerstone of all design disciplines.
Our journey in this post covered a wide array of topics—from color theory to textures in interior design, from the magic of natural light to the power of biophilic design, and from the importance of symmetry to the creative possibilities of shapes and forms. These are the tools in our interior design toolkit, and the principle of similarity is the thread that stitches these tools together.
This principle doesn’t just result in spaces that look good—it creates spaces that feel good. Whether it’s the continuity provided by similar shapes, the calming effect of a coherent color palette, or the inviting ambiance created by matching textures, this principle leverages the power of similarities to create spaces that resonate with the human brain’s inherent design preferences.
In essence, the principle of similarity in interior design is about tapping into our innate desire for order and unity. It’s about creating spaces that not only please the eye but also provide a sense of comfort and harmony. It’s about recognizing the powerful relationships that exist between similar elements and using this to our advantage to create truly inspiring spaces.
To all budding designers, I encourage you to harness this principle in your designs. It’s the golden thread that has the power to tie your designs together, crafting a visually consistent and deeply satisfying experience for the users of your space. Let’s continue to explore and apply this principle in our work, using it to create spaces that feel as good as they look. Happy designing!
Similarity in Interior Design – FAQ
1. How does the principle of similarity in interior design impact the overall aesthetic of a space?
The principle of similarity in interior design plays a pivotal role in creating visual harmony. By grouping similar elements together, like colors, shapes, or textures, interior designers craft a sense of cohesion. The human brain naturally identifies these similarities, leading to an aesthetic that feels well-orchestrated and satisfying.
2. How can symmetry, a form of the principle of similarity, be applied in interior design?
Symmetry is a key component of the principle of similarity. For instance, a room can showcase symmetry through similar furnishings on either side of a central point, creating a mirrored effect. This balance imparts a sense of calm and orderliness, which is appealing to the eye and mind.
3. In what ways does the principle of continuity interact with the principle of similarity in interior design?
The principle of continuity and similarity go hand in hand. By maintaining similar elements across a space, designers create a sense of flow and connection. It might involve repeating a specific color, texture, or design element throughout different sections of a room to weave a continuous narrative.
4. Can you provide examples of how Gestalt principles are utilized in interior design?
Absolutely! The Gestalt principles, such as similarity, closure, and continuation, are integral to interior design. For example, using similar colors or shapes (similarity) in different areas of a room can create unity. The principle of closure might be utilized by arranging furniture to form an implied shape or area. Lastly, the principle of continuation could be achieved by aligning artwork or decorative elements in a way that guides the viewer’s eye around the room.
5. How does the principle of closure relate to similarity in the context of interior design?
The principle of closure works with similarity to create well-defined spaces in interior design. It suggests that our brains tend to fill in missing information to perceive a whole image. So, even if your furniture or decor isn’t perfectly similar or symmetric, the brain will find patterns and connections, creating a sense of completeness and uniformity.
6. Are there any popular design trends that explicitly use the principle of similarity in interior design?
Indeed, trends like minimalist design, Scandinavian design, and monochromatic color schemes heavily rely on the principle of similarity. These styles employ repeated patterns, colors, or shapes to establish a serene and cohesive atmosphere.
7. How does the principle of similarity play a role in product design, similar to its role in interior design?
In product design, the principle of similarity helps create intuitive and user-friendly experiences. Just like in interior design, similar elements are grouped to guide the user’s attention and expectations. For example, buttons with similar functions in software may share the same color to indicate their related purpose.
8. How is psychology, particularly the human brain’s perception of similarity, leveraged in interior design?
Interior designers often apply principles of psychology to enhance spaces. The human brain naturally seeks out patterns, so the use of similar elements can make a room feel harmonious and balanced. It’s about leveraging our natural tendencies to perceive and group similar items together to create aesthetically pleasing environments.
9. How can principles from UX design, like the principle of similarity, be applied to interior design?
Just like in UX design, the principle of similarity in interior design aims to create intuitive, user-friendly spaces. By using similar elements—be it color, shape, or materials—designers can guide the viewer’s eye and create visual hierarchies. This can help occupants intuitively understand the space and navigate it more easily.
10. How can I incorporate continuity and similarity in my living room design to create a cohesive look?
Creating a cohesive look in your living room can be achieved by thoughtfully incorporating elements of continuity and similarity. Begin by choosing a consistent color scheme or a unifying theme. Carry these throughout the room, be it in the choice of upholstery, curtains, rugs, or wall decor.
