Design is not just about beauty. A good design will be simple, balanced and comfortable to use. Design principles are the foundation for any successful interior space layout. Interior designers are responsible for designing spaces that are functional, aesthetically pleasing and meet the needs of their clients. The first step in creating a great design plan is understanding what you want it to accomplish for you or your client so that you can create an atmosphere that brings out the best in people living there. Every aspect of a home has some sort of function or purpose. And some aspects have over one function at once (such as lighting). Your design should consider all these different functions while also considering how to arrange furniture and other elements within your space.

Whether you’re designing your first apartment or your tenth, the principles of interior design will always be important. There are many considerations to consider when designing a space. But what matters most is creating functional spaces that suit your desired lifestyle and needs. Here are the 7 principles of interior design basics on how to get started with interior design.

  1. Rhythm
  2. Emphasis
  3. Contrast
  4. Harmony & unity
  5. Scale & proportion
  6. Details
  7. Balance


Rhythm is all about movement. In design, this means that we need regularity with repetition to create a sense of continuity from one element to another for our space designs. The progression should have some sort or transition between it so as not to be too boring or stagnant. Keeping these principles will help you achieve rhythm within your interior decorating scheme at home.

  • Repetition

Repetition is the use of same element more than once throughout a space, such as having coat hangers in one closet and clothes on them. You can repeat patterns, colors and textures but also lines or other objects within your design to achieve the rhythm.

  • Progression

Progression is one of the most fundamental principles in design. It’s used to create interest, variety and mood by varying elements like size or color across an object/room, etc. You can even achieve this with your candles on a simple tray.

  • Transition

Transition is a little more difficult to define than repetition and progression. Transition has an easier flow, so the eye naturally glides from one area into another with less effort. One common form of transition would be using curved lines, like those found in arched doorways or winding paths that guide you through this space effectively without feeling too jarring for visitors’ eyes.

By including these 3 factors that are repetition, progression and transition, one can easily achieve rhythm in their project


Emphasis means creating a focal point. Every room or space has its own focal point. It can be an architectural object like the fireplace or oversized artwork in one’s home. Yet there are other ways to add emphasis, such as color use on wall surfaces. For example, using neutral tones with bold patterns will make them stand out more than if they were plain white walls throughout your entire house.

A great way designers accomplish this goal without overdoing it too much would involve highlighting specific features. Within their designs, by strategically placing accent pieces which can include anything from objects down to specially designed lighting fixtures.


A simple way to add contrast in your room is through color. Nothing creates a visual impact quite like using black and white. Another popular option for homeowners on a budget would be brown furniture with cream upholstery. Another technique you can use is having one large mirror above each sofa and side table as well. Two square ottomans sitting around below them at either end. Place an elegant roundabout stand-alone piece next time. This will give off more contrasting shapes while remaining eye catching.

The contrast in a room can be heightened by including areas that have both positive and negative visual activity. This will create more depth when arranging the contents of your living spaces.


The elements of design are always at work together to create a message. Harmony creates an atmosphere for relaxation and calmness with its soothing perfectionism in one color alone. Even though you vary in shape-size textures, etc., harmony is created when all the components act towards sending out unified energies.

Unity is necessary to link all interior spaces. Using various disparate styles throughout a home results in visual interruptions as you travel from one area to another. But it’s easy enough if each room works together with similar design elements such as complementary colors and shapes. This way, there will be no jarring transitions between areas because of different color schemes or textures used within them.


The importance of scale and proportion in interior design is a well-known fact. With these principles, it’s possible to create beautiful spaces that are both aesthetically pleasing and functional for their inhabitants’ needs. Which makes them an invaluable asset during any home renovation or addition. Let’s look at what the difference between them means:

  • Scale

A scale is a relative measurement of two objects. For example, the height of table and chair are determined by how many millimeters they differ from one another in size. While defining what an appropriate bathroom or shower should be. This concept applies to all scales except for exact measurements where we can determine both objects sizes with certainty.

  • Proportion

The relationship between two different objects in a room can be described in the term proportion. It’s important for designers to understand how they relate so that everything feels balanced and cohesive. In other words: your coffee table needs to be 2/3 as long as your couch – if not more. This is how scale and proportion work for interior design.


Interior design is more than just what you see on the surface, interior designers need to pay attention to details such as color and material selection for each room in order to create an atmosphere that makes it feel like home rather than just another boring building with no personality. This means paying close attention to every aspect, from paint colors down to door hardware so that everything has its own special touch while still maintaining functionality.


Interior design is all about balance. It’s the essence of visual composition, and it can apply to any number or aspect within your space, such as color schemes or furniture placement. There are three major ways you need to keep this in mind:

  • Symmetrical balance

In traditional interiors, symmetry is often used to create balance. Symmetry is an attribute of shapes that repeats the same image on either side and vertical axis. Like you might remember old rooms where there were mirrors across from each other, for example (think Poltergeist). This symmetry also reflects our human form so that we are innately comfortable with an environment that has been balanced out perfectly.

  • Asymmetrical balance

Asymmetrical balance is the more popular choice in design. In design, balance is achieved with equal visual weight or eye attraction. This means that the same amount of attention should be given to both sides of a page. But there are some dissimilar objects that give it an interesting look and feel. Which may lead you to move around more sensuously inside your home. Asymmetry suggests movement so dynamic interiors would appeal to most people’s senses.

  • Radial balance

While rarely employed in interiors, radials can be an interesting counterpoint if used appropriately. A spiral staircase is a great example of radial balance and symmetry. Because all elements revolve around their center point, with each turn being more intense than the last until reaching maximum intensity at its furthest extent before returning to begin again from where it left off.
