If you use this rule, you'll learn to just concentrate on the important points and leave the fluff out. Needless to say, it does depend on the type of presentation you're giving and the audience. Try to stick to 10 slides, its okay if you have to go to 12-14 slides. Read more at the original source:
- 20 Minutes to deliver the presentation
- 30 is the minimum font size you are to use.
A PowerPoint presentation should have ten slides, last no more than twenty minutes, and contain no font smaller than thirty points. While I’m in the venture capital business, this rule is applicable for any presentation to reach agreement: for example, raising capital, making a sale, forming a partnership, etc.
Ten slides. Ten is the optimal number of slides in a PowerPoint presentation because a normal human being cannot comprehend more than ten concepts in a meeting—and venture capitalists are very normal. (The only difference between you and venture capitalist is that he is getting paid to gamble with someone else’s money). If you must use more than ten slides to explain your business, you probably don’t have a business. The ten topics that a venture capitalist cares about are:
- Your solution
- Business model
- Underlying magic/technology
- Marketing and sales
- Projections and milestones
- Status and timeline
- Summary and call to action
Twenty minutes. You should give your ten slides in twenty minutes. Sure, you have an hour time slot, but you’re using a Windows laptop, so it will take forty minutes to make it work with the projector. Even if setup goes perfectly, people will arrive late and have to leave early. In a perfect world, you give your pitch in twenty minutes, and you have forty minutes left for discussion.
Thirty-point font. The majority of the presentations that I see have text in a ten point font. As much text as possible is jammed into the slide, and then the presenter reads it. However, as soon as the audience figures out that you’re reading the text, it reads ahead of you because it can read faster than you can speak. The result is that you and the audience are out of synch.
The reason people use a small font is twofold: first, that they don’t know their material well enough; second, they think that more text is more convincing. Total bozosity. Force yourself to use no font smaller than thirty points. I guarantee it will make your presentations better because it requires you to find the most salient points and to know how to explain them well. If “thirty points,” is too dogmatic, the I offer you an algorithm: find out the age of the oldest person in your audience and divide it by two. That’s your optimal font size. (c) источник
