1. DON’T Don’t mix up your fonts just because you think it looks good .
2. DO Vary font for emphasis or to group words together .
3. DON’T Use serif fonts, like Times New Roman. They are harder to read on a screen.
4. DO Use non-serif fonts like Arial or Helvetica for the screen. They are easier on the eye.
5. DON’T Ever underline words for emphasis . People mistake underlined words for links. They are also harder to read. Don’t Use ALL CAPS in sentences. PEOPLE MIGHT THINK YOU ARE SHOUTING!
9. DON’T Fill up the screen with lots of small text which in fact you intend to read out word for word. People find it hard to listen to what is being said if they can read it at the same time. This is because we can read faster than we can talk. So, please avoid doing this in your presentations. Also of course small text on a screen is hard to read. There is nothing worse than being presented with a screen of too much information, the audience will feel overwhelmed and confused.
