What is a common guideline for using visual aids during a presentation?

Ensuring that visual aids are visible to everyone is essential for effective communication during a presentation. When visual aids are used, their primary purpose is to enhance understanding and retention of the information being presented. If the audience cannot see the visuals clearly, whether due to poor lighting, distance, or inadequate size, the effectiveness of the presentation is significantly diminished.

Visibility ensures that all audience members, regardless of their seating position, can access the information being displayed. This accessibility fosters engagement and allows for a more interactive experience, as audience members can reference the visuals as the speaker discusses key points. In essence, the visibility of visual aids contributes to a smoother flow of information and helps maintain the audience's attention, leading to a more successful presentation overall.
