Have you ever walked into a home and felt immediately at peace? Like somehow every choice just flows into a beautiful space. That’s the magic of interior design. While your space should reflect your aesthetics and desires, there are seven principles of interior design to follow for a more cohesive look.

The interior design consultants at Designer’s Mark are here to help you understand the key principles of creating an enviable space.

What Are Interior Design Principles?

Incorporating these principles is critical to designing a unique, inviting space. Not everyone has the same home decorating style but some methods and tools allow us to have a better grasp on the best techniques.

Here are the main seven principles to keep in mind while designing your home.


One of the most critical elements of design theory is to guarantee that there is a semblance of unity in the area. Unification can easily be achieved by having similar elements such as colors, patterns, and textures. Other great aspects include spacing and repetition of accessories and furniture. Applying this technique allows for a sense of visual continuation and a cohesive feel.


Balance means all elements have proper distribution and space. Colors, patterns, shapes, and textures all help to achieve equilibrium in your design. There are three main ways to achieve design balance. They are:

  • Symmetrical Balance: This traditional balance places objects at an equal distance from each other.
  • Asymmetrical Balance: This balance places dissimilar or oddly numbered objects of similar dimensions together.
  • Radial Balance: This balance places objects around a usually circular focal point like round tables or lighting.


Humans are inherently drawn to patterns of repetition and contrast. Rhythm allows you and others to move their eyes around a room with interest. One way to achieve this is by incorporating different sizes of objects in similar colors throughout the space. Another way to achieve a distinct rhythm is by incorporating the same color in different shapes. For example, try picking up your favorite color in different places like vases, paintings, and pillows.


The unification of your aesthetic vision and incorporation of interior design principles is the idea of harmony. While rhythm creates the excitement we crave, harmony provides the juxtaposition of peacefulness. Similarities in form, shape, texture, and color are some of the easiest ways to achieve a harmonious design. A cohesive space is easier to take in because it feels more welcoming.


Every space needs one definitive focal point. The principle of emphasis is to act as an anchor, so the room doesn’t feel chaotic or boring. One of the best aspects of emphasis is that, it is totally up to your personality. If you’re very musical, include a grand piano. If you’re artistic, include a unique piece of artwork. As many people have architectural focal points like fireplaces or windows, you may want to emphasize these by grouping your furniture around these features.

Scale And Proportion

The difference between these two can be confusing. While scale is the relative size of separate objects, proportion is the relative size of objects to a whole.

For example, scale would be the size of a chair compared to a coffee table. Proportion, on the other hand, would be the size of a vase compared to the entire room.

Both are essential to interior design, so objects don’t look awkward in your space. Designer’s Mark consultants are experts in implementing the golden ratio of the two in any area of your home.


As they say, the real big picture lies in the details. When it comes to showcasing your designer style, nothing is too small or unimportant. From the pattern on your curtains to the frames on your wall, every little touch is a brilliant example of personality and design.
