What size font is recommended for optimal visibility on posters?

Using large font sizes on posters is essential for optimal visibility, particularly because posters are often viewed from a distance. The primary goal of poster design is to convey a message quickly and effectively to a broad audience, including those who may not be in close proximity. Large fonts ensure that the text is easily readable from afar, enhancing the chances that viewers will notice and understand the information being presented.

Large fonts also help in grabbing attention. They make the key messages stand out in a crowded visual environment, which is crucial in settings like conferences, events, or public spaces where many visual elements compete for viewers’ focus. In general design principles, ensuring legibility and clarity is paramount, especially in mediums where quick reading is necessary.

While medium, small, and extra large fonts may have their specific uses in different contexts, large fonts strike the best balance for posters as they can be seen clearly without requiring viewers to strain their eyes or move closer to the presentation.
