You’ve just been asked to give a project update to your colleagues at next
week’s lunch-hour seminar. Quick… How many slides will you use? 你要使用多少张PPT? Don’t know? Guy Kawasaki, a famous author and venture capitalist, has the
answers and they may surprise you.
What is the 10-20-30 Rule for PowerPoint? 10 slides are the optimal number to use for a
presentation. 20 minutes is the longest amount of time you should
speak. 30 point font is the smallest font size you should use on your
slides. 1: 10 Slides Constrains the Presenter to Choose
Wisely Sure, 10 may seem like an arbitrary number, but putting a limit on the number
of slides you are allowed is a valuable constraint. Most people probably have
20, or 30, or 100 slides for a 1-hour presentation. Trimming this number down to
10 forces you to evaluate the necessity of each and every slide. Just like every
element of your presentation, if the slide isn’t necessary, it should be
cut. It also encourages a presenter to design wisely. Often a single well-designed
diagram eliminates the need for 5 bullet-point slides.
2: 20 Minutes is Long Enough to Communicate Something
Big Just like the constraint on the number of slides, a constraint on your
speaking time will force you to edit mercilessly. Trim the sidebar jokes. Trim
the gratuitous “I’m happy to be here” pleasantries. Trim the stories which
aren’t essential to conveying your message. Trim the details that only 5% of the
audience cares about — send them out via email later. When you are able to trim
all the extras, you can communicate with precision and
concision. Martin Luther King Jr. only needed 17 minutes to share his dream. What makes
you think you need more? 3: 30-Point Font Guarantees
Readability Unless you have a very large audience and a very small projector screen,
30-point font should be readable by everyone in your audience. Bigger is
probably better, but this is a sensible lower threshold to adopt.While a
30-point font still allows you to put too many words on a slide, at least your
audience will be able to read
them. If everyone were to follow this advice, the overall quality of business
presentations everywhere would improve
dramatically. |
