Choosing Right Font Size
How do you choose the right font size for your presentation? It is very difficult to judge exactly how readable projected text can be to an audience when preparing a presentation on a computer. As a general rule of thumb, never use font sizes below 12 points. Ideally body/ bulleted text should be 18 points and above. Headings and important words/ phrases should be 30 points and above.
