Rhythm creates a sense of movement through repetition, contrast, or progression, and emphasis highlights focal points or areas of interest. Harmony is achieved by unifying the design through a consistent theme or style.

The elements of interior design consist of space, line, form, color, texture, and light. Space is the area within which the design takes place, and it can be divided into positive (occupied) and negative (empty) spaces. Lines define shapes and forms, and they can be horizontal, vertical, or dynamic (curved or diagonal). Form refers to the shape and structure of objects, which can be geometric or organic. Color is a powerful tool that can evoke emotions and set the mood of a space, while texture adds depth and interest through tactile and visual variations. Lastly, light is essential for enhancing the overall design, as it influences the perception of colors, forms, and textures (Ching, F. D. K., Binggeli, C., & Ballast, D. K. (2012). Interior Design Illustrated. John Wiley & Sons.).
