Which principle concerns the size relationships between elements to create balance?

• A. Movement
• B. Proportion and Scale
• C. Rhythm
• D. Contrast

Answer: (B)

Size relationships among elements are governed by proportion and scale. Proportion is about how the sizes of parts relate to each other within a design, while scale is about how those elements read in relation to a human size or the surrounding context. When these relationships are harmonious, the composition feels balanced and coherent because visual weight is distributed evenly and the eye can move naturally across the form. If one element is oversized compared to its neighbors, it can dominate and disrupt balance; if elements are too small, the composition may feel fragile or insignificant. Using consistent proportions—often guided by grids, modular systems, or human-scale references—helps achieve a stable, comfortable reading of the design. For example, façades whose window modules and wall panels follow a unified proportion read as orderly, and interiors arranged to (fit) human scale feel inviting and balanced. Movement, rhythm, and contrast influence how a design is experienced in other ways, such as the eye’s path, repetition, or differences in color and texture, but they do not fundamentally address the size relationships that create balance.
