What is the traditionally accepted number of fonts for an ad layout?

Using two fonts in an ad layout is traditionally accepted because it strikes a balance between aesthetic appeal and functionality. This approach allows for the use of a primary font for the body text, which ensures readability, while a secondary font can be utilized for headings or emphasis, adding visual interest and hierarchy to the design.

Using just one font might create a stark and limiting design, lacking in variety and differentiation between text elements. On the other hand, employing three or four fonts can lead to visual chaos, making the advertisement harder to read and understand. Too many fonts can distract the viewer and dilute the message, thereby reducing the overall effectiveness of the advertisement. The use of two fonts helps maintain a cohesive and professional look, making it easier for the audience to engage with the content.
