handouts without an inch and a half of lost space at the bottom. First two pieces of advice for giving presentations:
(1) Never apologize (especially not at the beginning of a presentation). -- It sets the wrong tone for your talk and is more likely to make your audience disregard you as amateurish than to elicit tender sympathy.
(2) Don‘t try to cover too much material. -- You should strive for clarity not quantity and should cover at most two (maybe three) main points. Your audience will attend as many as 12 talks the day that they see yours. You want them to remember your main point and argument the next day.
Jason Riggle's theory of optimal handouts:
It can be tempting to try to impress your audience with the fact that you have nailed down every little detail of an analysis or to try to include a counterexample for every plausible alternative hypothesis or to make the handout a stand-alone document that contains your entire analysis. These are all mistakes. If you have all this worked out it should be in a paper on your web page and you should put a link to the paper on the handout. First and foremost, the handout is a visual aid for your talk that should help you get your audience excited enough about your work to go read the paper, invite you out for a colloquium/job talk, or give you a job. I personally think that you should never plan on skipping material on the handout. Even skipped data that merely fill out a paradigm you are discussing invite your audience to stop paying attention to you and to start reading the skipped material. You should also never run out of time during a talk (or run short by more than 30 seconds). This is easy to avoid if you plan on covering the right amount of material and practice giving your talk while watching timer ? a small timer that counts down to zero is ideal for this purpose. I think that one sheet of paper printed 2-up and double sided is ideal for a 20 minute talk but if you have graphs, trees, maps, or other such things you might need a little more space. In my opinion you should never exceed six pages for a 20 minute talk because if you do then you are either talking too fast or skipping too much material. If you decide to use six pages you can do it on two pieces of paper printed 2-up and double sided with the back of the second sheet (pages 7 and 8) devoted to references and an appendix. To keep your 2-up pages from being illegible follow these instructions:
*Printing 2-up in MS word* -
Click on [File] and then select [Page Setup] in the drop-down menu.
Click on the [Margins] tab and set the Top, Bottom, Left, and Right margins to 0.5 inches
Click on the [Paper] tab and change the width and height of the paper to 7.5” and 11.5”.
When you print the paper (i.e. click on [File] and select [Print]) the lower right corner of the print menu has a field called 想oom’. In this field are two boxes one labeled images per sheet” and the other labeled scale to paper size” - set the former to [2 pages] and the latter to [letter].
Under these settings 12 point fonts are legible and you have the same 6.5” wide column for your content on each page that you have on letter paper with 1” margins. Each page has 10.5 inches of vertical space for you content which is 1.5” more than you get on letter paper with 1 ” margins. The net result is that you get an extra 2/3 of a page of content in a 4-page handout (which should just be enough space for selected references and web links to appendices and or the full paper).
You play around with the paper size and margins to suit your needs but these settings are a pretty good place to start. Good luck with your presentations, and have a nice winter break.
