One size doesn't fit all.

The decision about what size of font to use is tough. You'll find that the larger the text, the easier it is to see from the back of the room. On the other hand, you'll be able to fit less text on each visual (that isn't necessarily a bad thing). There are two rules of thumb to keep in mind:

• Use one visual to illustrate each concept. Here's a chance to learn more about using visual aids and the progressive disclosure of information to make learning a complex concept easier.
• We tend to see most fonts printed in a 10 - 12 point size, in textbooks and on computer screens. Larger text looks strange, and we tend to overestimate how big text sizes larger than 18 point will actually be when projected onto a screen. If the text looks big enough to be the right size (18-24 point), it's probably too small. Make the text so large that you feel it must be too big (36-48 point) - it will probably be just about right.
  
  

Another decision about text size has to do with the text format. There are no rules about whether to left, center, right, or fully justify blocks of text. On the other hand, a mixture of upper and lower case characters is easiest to read.

Now, what about the Color Scheme?
