Designing presentation slides
There is an art to designing effective presentation slides. Consider the following design features.
Use simple, contrasting background and text colors such as black on white, or white on dark blue. Elaborate designs and color schemes can overwhelm the content. Which of the following two slides is more effective?
Choose a clear font and make headings approximately 36 points in size and text at least 16 points.
Don’t try to include too much information on a slide. If there is too much content the audience will not be able to take it all in.
Animation and sound effects
Use animation and sound effects sparingly and only when they contribute to the point you want to make.
Choice of graphics
Choose the right type of graphics for your purpose. For example, bar graphs can be used to compare, line graphs to show changes over time and pie charts to show percentage of total.
There is an art to writing bullet points. They should:
- convey precise meaning as concisely as possible
- be written in the same grammatical form.
Don’t have so many slides that you have to race through them. Generally, one slide per minute is about right, but of course you can vary how long you spend on each.
