Interior design refers to the professional activity of planning, arranging, and decorating interior spaces to create comfortable, practical, and aesthetically pleasing living or working environments. Interior designers typically need to consider various aspects such as functionality, aesthetics, material selection, color coordination, and more when working on a project. To better meet the functional needs of users, improve space utilization, and create a comfortable environment, interior design often adheres to several effective principles.
This article will share with you seven common principles in interior design. While they are not strict rules, they serve as guiding principles during the design process, enabling you to comprehensively consider various factors to achieve a balance of functionality, aesthetics, and comfort in the created space. Now, check them out!
1. Balance
In interior design, balance refers to the rational distribution and organization of various design elements within a space to create a stable and harmonious overall look, avoiding the perception of an area being too heavy or empty. Spatial balance can be achieved through adjustments in color, shape, and texture, as well as the arrangement of furnishings and decor.
- Color Balance: Utilizing color to balance a space is a crucial method. Achieving balance on a larger scale can be done by using similar tones or color families throughout space. It is essential to avoid excessive use of bold colors in one area while using overly muted ones in another.
- Shape and Texture Balance: Incorporating elements with different shapes and textures in the interior adds depth and interest, preventing space from appearing monotonous.
- Distribution of Furnishings and Decor: When arranging furnishings and decor, it’s important to consider their size, height, shape, and distribution throughout the space. It’s better to their visual weight and avoid concentrating all significant elements in one area.
Balance can be symmetrical or asymmetrical, depending on the design goals and style. Symmetrical, asymmetrical, and radial balances are three common types of balance in interior design. They are flexibly employed in design to meet various objectives and style preferences.
Symmetrical or Formal Balance
Symmetry is perhaps the most straightforward and traditional form of balance in interior design. Symmetrical balance involves dividing the space into equal halves, ensuring each side has a similar quantity and type of furniture, decor, or other design elements to achieve an overall stable and symmetrical effect. This balancing approach is commonly employed in traditional and formal design styles.
To achieve a fast completion of symmetrical layouts in a space, designers can use the copy function within home design software, which allows them to effortlessly create elements on one side of the sketch that mirror symmetrically on the other side with just a click. This significantly reduces drawing time and enhances overall efficiency.
Asymmetrical or Informal Balance
In contrast to symmetrical balance, asymmetrical balance involves using different design elements in a space instead of creating a mirrored effect. Designers achieve overall balance by balancing the visual weight of these flexible items, such as using large or dark elements in one area and small or light elements in another. This type of balance is common in modern, artistic, and eclectic interior design styles, creating more creative and personalized spaces.
Radial Balance
Another classification is radial balance, a more complex approach involving the extension of design elements outward from a central point, forming a radial layout. For instance, making a fireplace the focal point in a space and placing other items facing towards it. Radial Balance is often applied in circular rooms, round dining tables, spiral staircases, and other designs, creating a unique visual effect.
2. Unity
In interior design, unity refers to creating a sense of completeness and cohesion throughout the entire space by incorporating coordinated and harmonious design elements. Various design elements, colors, materials, and styles within the space should complement each other, forming a unified whole rather than isolated parts. Achieving unity in interior space can be considered through the following aspects:
- Color Coordination: To achieve unity in interior design, it’s better to select one to two dominant colors and the others as complementary tones. This distribution ensures color coordination throughout the entire space, including walls, ceilings, modular sectional sofa, and decor.
- Consistency in Materials and Texture: Employing similar or identical materials and textures ensures a connection between elements within the space. For example, all rooms feature wooden flooring and furniture with a striped texture. This ensures coherence and creates a consistent overall feel.
- Consistency in Style: Choosing and consistently applying a specific design style, whether it’s modern, traditional, or artistic, is crucial. Elements from different styles may conflict within the same space.
3. Rhythm
In interior design, rhythm typically refers to the organized arrangement and repetition of elements within a space to create a visual dynamic and sense of balance. Rhythm helps make the interior space appear more organized and layered. As the human brain is naturally drawn to repeated and similar objects, rhythm also guides people to carry visual interest around the room. Rhythm is mainly classified into the following three categories:
- Repetition: Creating a sense of rhythm by repeating similar or identical elements within the space. For example, painting walls with a brown hue and choosing sofas or chairs in the same color. Repetition enhances the consistency and unity of space, making it more orderly, and neat, and providing a sense of familiarity.
- Transition: Introducing variations within the repetition can generate a more dynamic effect. Transition involves gradients or changes in color, shape, size, or other design elements, such as introducing a contrasting color within a similar color palette. Transition adds a sense of flow, making space more lively and avoiding monotony.
- Progression: Progression involves gradually increasing or changing the characteristics of an element to create a progressive effect. This can be achieved through gradual changes in color, size, shape, texture, and more. For instance, in a long corridor, gradually changing the height or color of lighting fixtures to create a progressive effect. This makes the entire space more interesting and captivating.
4. Scale and Proportion
Scale and proportion are two critical concepts in interior design. Designers must consider these factors to ensure a balance among elements and within the space.
Scale refers to the size of objects, emphasizing the relative dimensions of elements to the overall space or the internal proportions of elements, such as the size of a table, a sofa, a window, and so on. Scale is highly significant in interior design. For instance, envision placing a massive modular cabinet in a small room filled with items—it would make the already limited space feel even more cramped. Therefore, designers need to choose furniture that suits the size of the space, ensuring they neither dominate the entire area nor appear insignificant.
Proportion emphasizes the relative relationships between various parts within an element, ensuring harmony in their composition and proportions. For example, placing small chairs next to a large table may disrupt the proportion. In the design and art industries, the golden ratio, 1:1.618 — a concept originating from the Greeks — is often used to harmonize proportions. Designers employ this ratio to determine the size relationships of elements like furniture and wall decor, ensuring consistency in proportions and preventing elements from being excessively large or small.
5. Contrast
Contrast, as the name suggests, involves placing elements in a space that are opposite or markedly different. Contrast can be achieved through various means, including color, shape, texture, and more. The use of contrast makes certain elements in a space stand out, attracting attention. It also helps define boundaries and relationships between different elements, establishing a sense of hierarchy.
The simplest way to achieve contrast is through color, such as painting walls with white and choosing black furniture. Contrast can also be realized through different shapes, like introducing a square table in a circular room. However, it’s important to note that while contrast provides visual interest, too much of it can make a space appear chaotic, breaking the principles of harmony and unity mentioned earlier. Therefore, a balanced application of contrast is essential to maintain the overall aesthetic cohesiveness of space.
6. Emphasis
The principle of emphasis involves designating one or several important elements in a space as focal points, making them more prominent and eye-catching in the overall setting. A room without a focal point lacks a memorable aspect. A focal point can be a piece of artwork, a piece of furniture, or even a specific area within the room. In interior design, emphasis serves to convey design concepts, highlight the functionality of a space, or simply attract attention and create visual interest. When employing emphasis, designers need to ensure it aligns with the overall design style and theme, avoiding excessive use to prevent a chaotic or discordant effect.
There are various ways to achieve emphasis, such as using bright and contrasting colors in a relatively dim environment, hanging a uniquely designed pendant light in a dining area, or dedicating a wall in the room to showcase artwork. The key is to strategically incorporate emphasis to enhance the overall visual appeal while maintaining coherence with the overall design.
7. Details
The final principle is attention to detail. As the saying goes, “The devil is in the details.” As a designer, even the smallest elements in interior design should not be overlooked. Unlike the previous principles, the details principle reflects more of your personal preferences. From patterns on a vase to accessories on a refrigerator and the color of wardrobe door handles, these small yet intricate elements may not immediately catch the eye but contribute to showcasing your personal style, making your design space unique, and adding charm to your interior.
Final Words
These are the seven crucial principles in interior design. Understanding these principles provides a foundation for mastering interior design and following these principles in practice helps create a space that satisfies both you and your clients.
On the other hand, interior design, as a discipline that combines art and science, involves considerations beyond these principles, such as the selection of professional interior design software, client needs and expectations, budgeting, and cost control.
