The overall design refers to the general layout, structure or appearance of something. It is an all-encompassing term that describes how different elements come together in a cohesive and harmonious manner to create a final product or outcome. In other words, it's about the big picture - the way everything fits into place to form a complete whole.
In terms of graphic design, overall design refers to the visual style, color scheme, typography, layout, and other elements that contribute towards creating an identity for a brand or product. It is how all these different components work together to create an impression on the viewer.
Overall design can also be applied in architecture, where it encompasses the entire building's structure, layout, materials used, and overall appearance. In interior design, it refers to the way furniture, decor, lighting, and other elements are arranged within a space to create an inviting atmosphere.
In summary, overall design is about how all the different parts of something come together in harmony to form a cohesive whole that communicates its intended message or creates a desired effect.
