It is often a good idea to give out any paper copy, like handouts of your outline or a glossary of key words or sources and any other visuals you plan to use so people can take them away, not waste time in taking notes on key concepts which you have put on the transparency and to avoid the problem of some people not being able to see the screen.

It is usual to put your name, the name of the conference or occasion, the date and the title of the presentation
together with any corporate or institutional logos.
Full sentences should not be used, unless a quote is given, try to keep text to a minimum.
Size - A4 Layout should be pleasant and easy to read. Landscape works better than portrait orientation as we are more used to reading information from screens.
are fine for text but may look weak for titles. Experiment a little to see for yourself.
Font size - maybe 20 or more depending on the size of the room you will be speaking in.
Use CAPITAL LETTERS, bold face, italics, underlining, reverse (white on black) or shading to highlight whenever necessary but only to give more clarity, not more variety. If possible it is usually a good idea to use color transparencies (unless you are just showing text).
One every two minutes is sufficient.
Visuals should be adjusted to the audience. Visual should supplement the spoken message. Large enough for everyone to see. (Good idea to give out a paper copy, not at the same time though as the audience may not be looking at you)
Ask yourself questions
Does the layout work?
Are there any spelling mistakes or grammatical errors? Remember they are going to be in plain view all the time of your visual so have them proof-read always.
It is not sufficient just to put up a transparency on the screen and expect the audience to move its attention to it, to understand it and make the link with what you are saying. (See Giving Presentations Unit. 4) I would suggest the following strategy:
1. Introduce subject. What does the visual show?
2. Transition. Let's turn to the visual.
3. Explain the visual in terms of the axes, key, and source.
4. Describe the visual (e.g. if it is a graph, describe the movement).
5. Comment and analyze.
6. Do not read everything. Do not explain every detail.
7. Use round figures and emphasise trends.
Finally it is important to prepare your audience for what they are going to see.This keeps the audience on their toes and gives you the opportunity to position your visual correctly.
Remember to draw the attention of the audience to the points that you wish to highlight but avoid redundancy by describing everything that is in the visual! A pause is very useful here!
You can also try to rephrase your point to give it emphasis, giving the audience time to absorb the information.
