Graphic design can use size to create visual hierarchy in a variety of ways. Scale, proportion, and typography are some of the most common and effective techniques. Scale is the relative size of an element compared to other elements or to a reference point, and it can be used to create contrast, drama, and perspective. Proportion is the ratio of one element to another or to the whole design, and it can be used to create balance, harmony, and rhythm. Typography is the art and technique of arranging text in a design, which involves varying the size of fonts as well as other attributes such as weight, color, alignment, and spacing. For example, you can use larger and bolder fonts for headlines and smaller and lighter fonts for subheadings. You can also use different font sizes within a text block to create hierarchy such as using a larger font for the first letter of a paragraph or using a smaller font for quotes, captions, or footnotes.
