Tips and techniques for effective PowerPoint presentations

Here is a consolidation of tips and techniques for making effectual PowerPoint presentations as related by experts like Nancy Duarte, Guy Kawasaki and Garr Reynolds.

Limit the amount of text and keep it simple

The first and foremost rule to making PowerPoint presentations is to make the slides as simple as possible. The focus of the audience needs to be on the speaker and not on the slide show, which merely works to assist the presenter. Your ability to convey a message can be disrupted by unnecessarily complicated slides, which will not supplement your presentation. Therefore, it is not necessary to fill all available space on a slide; rather one should not hesitate in leaving empty or blank spaces in the slides. An uncluttered slide will better convey the visual message that you intend to convey. Expert Guy Kawasaki has urged presenters to not have the font size smaller than 30 point font. Through this way only salient points of your presentation will fit into one slide and keep the presenter away from the temptation of muddling the slide with a colossal amount of information.
Slides are meant to support the words of the speaker and not make the presenter appear redundant. This will be the case if the slides contain a vast number of bullets and text with the speaker merely reading out text from the slide. The speaker needs to face the audience and know his content well so that he/does not depend on the slides for his speaking material.

This slide contains a colossal amount of text. Way more than necessary.


This one too contains too much text and will induce boredom


Something simple and classy like this slide conveys the complete message in a single sentence.


Thisis simpler, classier and conveys a complete message using the correct amalgamation of pictures and text.


Avoid using an excess of animations and slide transitions

There is a need for the prudent use of slide transitions and object buildups i.e. animations. An excess of the two will lead to boredom within the audience as the "Move" or "Fly" options are too slow and tedious. However, professional and artful animations can add to the efficiency of your slides. Therefore, the types of transitions should be limited to no more than three and should not be introduced between all slides.

Choosing of sensible fonts and use appropriate color combinations

Mostly people do not know the difference between different font types and what kind of font will be suitable for a PowerPoint presentation. Choosing of fonts has to be deliberate as they convey positive or negatives messages regarding your presentation slides. It is important to use the same type of font for the entire slide presentation and to use no more than two kinds of corresponding fonts e.g. (Ariel or Ariel bold). It is also imperative that we are able to distinguish between Serif and Sans Serif fonts. Serif fonts are more suitable for documents involving a large amount of text, however their use in PowerPoint slides will not allow for clarity as projectors have a low resolution. For PowerPoint presentations Sans Serif font is the most suitable. Regardless, of your font type it is essential that the text can be read from the back of the room.

Appropriate color combinations enhance the learning experience of the audience and help in retention. Colors can be categorized into either cool or warm colors. Warm colors include red, orange etc, which when used on a slide presentation seem to be coming at the audience. Therefore, the text of the presentation slides should be of the warm color category. Cool colors are to be used for the background of the presentations as they give the effect of receding away from the audience.

Use high quality graphics and a visual theme

Instead of using PowerPoint clip art it is better to include images in your slides that you might have taken from your own digital camera or the vast number of images available on the Internet. Usage of clipart does not give a professional touch to your presentation slides and the audience has probably viewed them repeatedly in many other PowerPoint presentations. Furthermore, to maintain a good quality resolution, rescaling of images to fit a certain space should be avoided. The Adobe Photoshop software should be used for modifying pictures so that they better fit the context of the slide.

Firstly, a visual theme common to all the slides is important so that the audience can maintain a sense of connection between all the ideas. The visual theme should be unique and new to the audience in order to hold their attention and interest. Therefore, it is advisable to design your own PowerPoint templates that have been modified to cater to the individual need of the presentation slides.

Use appropriate charts and graphs

For presenting statistical data, instead of stating a complex array of facts and figures, pie charts, vertical and horizontal bar charts and line graphs should be used.

A thorough explanation of the different types of charts as described by Garr Reynolds on his blog is as follows:

Pie Charts Used to show percentages. Limit the slices to 4-6 and contrast the most important slice either with color or by exploding the slice.


Vertical Bar Charts Used to show changes in quantity over time. Best if you limit the bars to 4-8.


Horizontal Bar Charts Used to compare quantities. For example, comparing sales figures among the four regions of the company


Line Charts Used to demonstrate trends. For example, here is a simple line chart showing that our sales have gone up every year. The trend is good. The arrow comes in later to underscore the point: Our future looks good!



The10/20/30 principle

The main principle of presentation making by Guy Kawasaki is the 10/20/30 Principle. This explains that the number of slides in any presentation should not be more than ten; the total duration of the presentation should be 20 minutes and the font size should not be less than 30 points. These principles are applicable mostly in a business environment. It stresses on the fact that an average human being cannot absorb a pool of ideas represented to him/her at one time; therefore a smaller number of slides limit the number of shared ideas.


Online slide sharing and searching

Coming towards slide sharing here are a few tips on how to upload PowerPoint slides on online slide sharing applications like SlideSix, myPlick, SlideShare and authorSTREAM. The online applications have a user friendly interface and first timers have no problem at all in uploading the required slides.
