Some Perceptual Tips
for Better Presentations

Presentation Goals
• Convey information• Concisely & effectively• Support & complement verbal
• Illustrate what words cannot
Presentation Goals
• It is NOT a paper• Time is limited• Present your key points• Present in a logical order
• Stick to your topic• What’s your point !
Basic Rules• Make It Big• Keep it Simple• Make It Clear• Be Consistent
Make It Big• Gauge your room size• Gauge audience distance• Title font = 54 - 60 point• Text font = 32 - 48 point• Use bold face font• Move 6’ from your computer
Font Size• 14 point font size
• 18 point font size
• 24 point font size
• 32 point font size• 36 point font size
• 48 point font size
• 60 point font size
Keep It Simple• San serif - no squiggles • Block letters• No italics • Mix UPPER & lower Case• Times, Arial, Century, Univers
• Bold, underline & color for emphasis
Fonts Types• Impact• Letter Gothic plain text• Bookman Italics• SyndieSyndie shadowed shadowed• Curlz MT• Arial bold• Blackadder ATC underlined
Make It Clear• 6 - 7 lines text per slide• ~ 7 words per line• Leave spaces• Avoid lots of text• Points vs complete thoughts
• Avoid punctuation ! . ; , “ ?
Do Not Crowd This is how to crowd a slide with way too much text!
The goal of this demonstration is to show the audience-distressing effects of crowding way too much information on one slide using as many words as possible in a font size that is way too small to make a multitude of extraneous and unrelated points so that the reader gets cross-eyed trying to read every word I have written in as short amount of time as possible without ever stopping. I have used plain text font at 24 point so it is even more difficult. I have not emphasized a single word. I have used lots of punctuation marks. As the bumper sticker says - if you can read this you are too close! Are you still reading or have you given up already as you should have long ago?
Make It Clear• Progressive disclosure of information
• Use multiple slides • Include only necessary info
• Make content self evident
Illustrations• Picture says 1000 words• Graphs & Tables• No more than 2 - 3 per slide
• 2 - 3 colors max• Do not crowd illustrations• Keep things simple

Graphs• Label the axes• Show units• Provide a legend• Use color 2 - 3 / graph• Clearly differentiate lines• 2+ graphs - consistent within & between slides

Visual Balance• English is read left to right
• Eyes tend to land on center
• Balance your slides• Center graphs / pictures• Fill screen L to R with text
Using Color• Use complimentary colors• Dark background - light text • Maximize contrast• Blue/red & green/red = bad• Shading - looks nice, hides text
Choosing Colors
Maximize Contrast
Red & blue is very bad
Red & green is very bad
Black & blue are bad
Blue & yellow are very good
Dark colors & white are very good
Black & neon green are pretty good
Shading• Text across shades of grading less visible
• Reading left to right or up & down 1/2 obscured
• Contrast significantly reduced• Eye strain increased• Some of your message gets lost
Pictures & Clip Art
• Use moderately• Compliments text• Humor is good• Don’t overshadow the text
Laser Pointers
Laser Pointers• Use moderately• Point to specifics• Know your slides• Don’t wave around randomly
• Don’t point at audience• Use text overlays instead
Arrows & Text
Right Ventricle
General• Talk to the audience• Not your notes• Not the screen behind you• Speak clearly & loud• Know your time limit• Practice your timing
