Several factors, such as room lighting and room size, affect the readability of your slides during a presentation. When creating your slides, choose font colors, styles, and sizes that make it easy for your audience to read what's on the screen, no matter where they're sitting.

The image below is an example of a poorly designed slide in terms of readability.
When changing font colors, choose colors that contrast strongly with your background. When selecting a font and background color combination, you should also consider the room in which you will be giving your presentation. Light fonts on dark backgrounds are often easier to read in dark rooms. Dark fonts on light backgrounds, on the other hand, work better in rooms with some light.
In the case of font styles, avoid fancy fonts like script styles. These fonts are hard to read on a computer screen and are nearly impossible to decipher when projected onto a screen. Stick to standard fonts like Arial, Times New Roman, or Verdana.
