One very important question to ask when designing presentation slides is:
“Will the audience be able to read your text?”
It seems like an obvious question but it’s clear from many presentations that this question isn’t asked, there are presentations crammed with so much information that the presenter has to use smaller and smaller text just so that they can get everything onto the one page, there are graphs with tiny illegible numbers on the axes and there is the increasing use of infographics that are filled with information that is not always readable on screen.
What’s worse if that some presenters recognize that their text is too small, yet they keep it in and instead say something like “This may be a bit too small to read so I’ll read it for you”
Let’s make it simple: if your audience can’t read the words on your slides then there’s no point putting those words on the slides.
