Size is arguably the most effective way to emphasize visual elements. Simply put, larger elements draw greater attention than smaller elements.

It’s the precise reason why newspaper headlines appear in larger fonts. In any design, larger elements—whether they be words or images—not only will be most noticeable, but they also will carry the strongest message.

Another important principle related to this concept is scale, the size of an object in relation to another. A large or small object, has no scale until it is compared. It allows us to create balance in design and focus on dominant elements.
