Layout can have a great effect on how your audience perceives and follows the structure, flow, and hierarchy of your information. It can also influence the aesthetics, balance, and alignment of your visual aids. For instance, a grid layout can create a sense of order and stability, while a freeform layout can bring out creativity and dynamism. When selecting the right layout for your visual aids, take into account the type and amount of information, the format and orientation of your visual aids, as well as the elements and principles of design. Think about if you have a clear message supported by relevant data, if you are avoiding overloading your visual aids with too much text or images, if you have the right format and orientation that fits your presentation medium and space, if you are using elements such as shapes, lines, and images to create visual interest and variety, or if you are using principles such as contrast, repetition, and proximity to create visual coherence and harmony.
