The title text is 36pt Segoe UI Light, the subheading text is 24pt Segoe UI, and the speaker info text is 14 pt Segoe UI.
Those font sizes alone make it very hard to read from the back of even the smaller rooms at the conference.
In addition to being too small, the gray text for the speaker info doesn’t have enough contrast from the white background. We want to get a contrast ratio of at least 4.5:1 (but 7:1 would be better). The contrast ratio for these colors is 4.0.
While sans serif fonts are generally thought to be easier to read in presentations, it’s better to use fonts with a stroke width that is not too thin – not necessarily wider characters, but thicker lines that make up each letter. So Segoe UI Light would not be my first choice for a title font, but Segoe UI or Segoe UI Bold might be ok.
Also, the red used on the right half of the slide is VERY bright for an element that is purely decorative, to the point that it might be distracting for some people. And the reason we need to squish our title into two lines of too-small text is because that giant red shape takes up half the page. What is more important: a “pretty” red shape to make our slide look snazzy or being able to clearly read the title of the presentation?
There’s a lot along these lines, and it’s great food for thought. Meagan includes a set of recommendations at the end, so be sure to catch those.
