Which type of visual balance is defined by arranging all graphic design elements along the vertical center of a page?

The correct choice is defined as formal balance. Formal balance, often referred to as symmetrical balance, occurs when elements are arranged evenly along a vertical centerline of a design or page. This type of balance creates a sense of harmony and stability because the elements on either side of the centerline appear visually equivalent.

In graphic design, formal balance is commonly used to convey professionalism and order, making it a preferred choice for designs that require a sense of structure, such as corporate branding or formal announcements. The centered arrangement of elements helps guide the viewer's eye equally across the page, promoting even distribution of visual weight and creating a cohesive look.

Other options, such as asymmetrical balance, involve a more dynamic arrangement that does not depend on symmetry but still achieves visual harmony through different shapes, colors, and sizes. Dynamic balance refers to a movement within the design that creates interest and excitement, while informal balance typically implies a more relaxed arrangement of elements that may seem less structured. These approaches have their own merits, but they do not conform to the strict vertical centering that characterizes formal balance.
