When it comes to creating effective presentations, one of the most critical elements to consider is font size. A well-designed font size can make all the difference in conveying your message and engaging your audience. However, choosing the right font size can be a daunting task, especially for those who are new to presentation design.

Understanding Font Size

Font size refers to the size of the text in a presentation. It is measured in points (pt), with 1 point being equivalent to 1/72 of an inch. The standard font sizes used in presentations are 12-point, 14-point, 18-point, 24-point, and 36-point.

The Smallest Font Size to Use on a Slide

So, what is the smallest font size that should be used on a slide? The answer is not as simple as it seems. While it may be tempting to use a small font size to fit more text on a slide, this can actually have the opposite effect. Using a font size that is too small can make your text difficult to read, especially for those who are seated in the back of the room or have vision impairments.

The American with Disabilities Act (ADA) Guidelines

According to the American with Disabilities Act (ADA) guidelines, the minimum font size for presentations should be 18-point. This is because font sizes smaller than 18-point can be difficult for people with visual impairments to read.

Why 18-Point is the Smallest Font Size to Use

Using an 18-point font size ensures that your text is clear and easy to read, even for those who are seated in the back of the room or have vision impairments. Additionally, using a font size that is too small can make your text appear cluttered and overwhelming, which can detract from the overall impact of your presentation.

The Drawbacks of Using a Smaller Font Size

Using a smaller font size can have several drawbacks, including:

Reduced readability: A smaller font size can make it difficult for your audience to read your text, which can lead to confusion and disengagement.
Increased eye strain: A smaller font size can cause eye strain and fatigue, which can detract from the overall impact of your presentation.
