In today’s digital world, where communication primarily occurs through social media platforms, there has been a noticeable increase in mental health challenges. As communication increasingly relies on digital formats, understanding how typefaces contribute to the transmission of feelings is becoming fundamental. The first impression a text makes is not only determined by its content but also by its visual execution, emphasising the need for a deeper exploration into how typography can evoke specific feelings and moods. This study examines how three sans serif typefaces—Open Sans, Quicksand, and Tenor Sans—affect psychological responses to mental health-related content. Using eye-tracking measures with 24 participants viewing positive, neutral, and negative phrases, the analysis reveals the impact of typeface on attention and emotional reception. The heat maps were used to identify which typeface participants were most fixated on and how the different typefaces influenced their reading behaviour. The methodology consisted of presenting 18 different phrases related to mental health, each written in one of the three selected typefaces. Each phrase was displayed randomly for 3 s, changing only the typeface. In analysing the emotional tone of the phrases, it was interesting to note that Quicksand maintained its position as the most preferred font even when paired with negative phrases. Although the study could not conclusively determine the extent to which typography affects the perceived meaning of a message, it’s clear that typefaces with softer, more rounded forms may have a more positive and inviting effect on individuals interacting with mental health content.
