Effective Slide Design

• When creating a slide be sure to have a font that can be easily read. Ex. Arial

• When selecting font colours try to stay away from light colours or yellows against light backgrounds.

• Also make sure the size of your font is legible from a decent distance so the back of your audience can read it.
