What are the 7 Elements of Interior Design

Before talking about the 7 basic elements of interior design we would like to make a small note. The problem with interior design is that many people confuse it with interior decoration.

In fact, the first one refers to the design of a complete living space from scratch . On the other hand, the second refers to decorating an existing living space with additional furniture and upholstery . Interior design is, in fact, a profession that is bound by its own elements and principles, and yes, it is not as simple as one imagines!

But don’t worry, we’ll cover the 7 elements of interior design in this article, followed by an article that explains the 7 principles .

Shall we start?

  1. SPACE

Space is one of the most important elements of interior design. The space acts as a foundation on which the entire interior design plan is built . Therefore, it is essential that the designer knows well the available space, its dimensions and its utilities. The space is divided into two types:

  • the two-dimensional space that covers the floor (includes length and width)
  • three-dimensional that forms the living space (includes length, width and height)

A balance must be maintained between positive and negative spaces . A space that is essentially full of furniture / decor elements is a Positive Space and an empty space is a Negative Space . Therefore, the abundance or scarcity of furniture / decoration elements will affect this balance.

  1. LINE

The lines give rise to forms and the forms are responsible for establishing a feeling of harmony. These define shapes and act as visual guides to an interior space. The lines are classified into three types:

  • Horizontal: those that add a sense of security to the space . They are used to decorate structures such as tables, chairs and beds
  • Vertical: they express a free and expansive nature . vertical lines can be found on windows and doors
  • Dynamic or angular lines, which are action- oriented , add drama and can be seen on structures like stairs.

An interior designer must know how to use these lines to define shapes, another important element of interior design.


A well- defined shape establishes harmony and additional shapes that add balance to the space. There are two types of shapes: geometric (artificial) and natural (organic) . They are also classified as open and closed ;

  • Open are those that can be examined
  • Closed are those that are enclosed by a surface

To achieve a proper shape, a combination of the space and line elements is required.

  1. LIGHT

Light is one of the most fundamental elements in interior design. Whether natural or artificial, no light, other elements like color, texture and pattern have no meaning. The light sets the mood and ambience in a living space and highlights all the other elements , including space, line, and shapes. Lighting is divided into three main types:

  • Task light, as the name implies, includes light sources such as table and bed lamps that have a defined purpose, dedicated to a specific task.
  • Punctual is intended to highlight a particular piece or an element of exhibition such as works of art, structures, sculptures, etc.
  • Ambient sets the mood of the living space and illuminates the space in general.
  1. COLOR

Colors establish an aesthetic connection between objects and create the environment . Colors should be chosen based on the psychology and mentality of the person. For example, red is an excellent option for the dining room, since it encourages appetite and green for the bedroom, since it is the color of tranquility and health. Each color has three distinct characteristics: Hue, Value, and Intensity , and an interior designer must know these characteristics to make various combinations.


Texture primarily deals with surfaces and determines how a surface looks and feels . This is generally classified into two types:

  • visual where the texture is only visible
  • real where the texture looks and feels

Everything that has to do with textiles like pillowcases, bedspreads or anything that has to do with covers like curtains, wall paint or wallpapers has a texture. While there must be a dominant texture to define a mood , a contrasting texture must also be included to avoid monotony.


The patterns add interest and life to interior design and work together with colors . In fact, they tell a story of their own and add continuity and smooth transition into a living space. The patterns can be any shape and mostly form attractive and repetitive designs .
