Don't put too much text on your slides. Use common Windows fonts Stick with the fonts that come installed with Windows. Using that option makes the file larger. However, it will also ensure your presentation looks like you intended it to. Be consistent Use the same background throughout.
Variety detracts rather than adds.
Use the same font throughout. Using a variety of fonts doesn't communicate information any better. For emphasis, use italics and bold. Make it readable. Use high contrast between text color and background.
