3 Most Important Interior Design Principles

It is said that Good design combines usefulness with at least one of the following: beauty, comfort, efficiency, economy, or durability. “Design is everywhere…It touches and affects everyone. Design is human-cantered.

Interior design is a multi-faceted profession in which creative and technical solutions are applied within a structure to achieve a built interior environment. These solutions are functional, enhance the quality of life and culture of the occupants and are aesthetically attractive. Interior design is the process of shaping the experience of interior space, through the manipulation of special volume as well as surface treatment.

An interior designer is someone who coordinates and manages such projects. Interior designer is a well paid person to get work according to the needs n space. Interior designers make sure that the interior spaces they are designing are always functional, safe, and beautiful for every type of buildings. Now as we have grasped about the basic information of interior designing n its substance so we can talk about the 3 main principles of the Interior Designing.

  1. Harmony and Unity
  2. Balance
  3. Rhythm


Harmony and Unity.

A beautifully decorated interior space should be highly functional but also evoke a mood and show off the personality of its inhabitants. Harmony can be described as sameness, the belonging of one thing with another. The repetition of design elements like color, texture, shape, and form is one of the easiest ways to achieve harmony to create a composition.

Unity is when the elements in a space combine to make a balanced, harmonious complete whole. The space feels right and everything works together. The result is a pleasing feeling, that everything is right with the space. When doing interior design it is necessary to think of the house as a totality.



It is a state of equalized tension and equilibrium, which may not always be calm. Just as when we are off balance in various aspects of our lives, an unbalanced interior space can be uncomfortable. This is achieved by distributing the visual weight of objects within a space to achieve a feeling of equilibrium. The size, colour, texture, shape of an element can change its visual weight. For example, larger, darker, brighter, highly textured, complexly shaped objects typically feel heavier and require balance through the placement equally “heavy” items or multiple less heavy items. Balance can also be achieved in three ways: symmetrically, asymmetrically and radially.

Symmetrical balance is achieved when items are actually repeated or mirrored along a central axis. This type of balance is frequently seen in nature, our own bodies included. Symmetry is common in interior design and can portray a feeling of stability, calmness and dignity.

Asymmetrical balance relates very strongly to the visual weight of objects. Rather than repeating the same item within a space to achieve balance, in this case we are using different elements with a similar perceived weight to achieve balance on the opposing axis. Asymmetrical interiors tend to feel more dynamic and less rigid.

Radial balance is almost circular – distributed arrangement of items around a central point either extending outward or inward. Common examples of radial balance translated to the interior environment include chairs cantered around a table, the structure of a circular rotunda.



Rhythm in interior design denotes creating visual interest throughout your space by repeating and contrasting visual patterns. It carries the eye along a path at a pace that is comfortable for the viewer. In order to achieve rhythm in your own home’s design, you’ll have to think about repetition, progression, transition and contrast. Incorporating these mechanisms into your interior, you’ll be able to create a sense of movement, leading the eye from one design element to the next within your home.

Repetition is one of the easiest ways to create a sense of rhythm in a space. Simply put, it is using the same element more than once throughout an interior. You can repeat patterns, colors, textures, lines or any other element within a space.
Progression is taking an element and decreasing or increasing one of its qualities. For example, using a gradation of colors or using a series of objects that go from small to large in a gradual manner.
Contrast uses two elements in opposition to each other and alternates these in a pattern that creates a sense of rhythm. You can create contrast with patterns (light and dark) and with shapes (circles and squares). A common example is alternating black and white pillows on a sofa.

Transition Rhythm through transition gently leads the eye through a continuous, uninterrupted flow from one area within a space to another. For example, curved lines are generally used to lead the eye along a desired path.
