xaringan: Easy way to change aspect ratio?

I would like to change the aspect ratio of a xaringan presentation to 16:9. I guess it would be possible if I would create a custom css theme. However, this would be somewhat of an overkill for me.

So, is there any really simple way of doing that?

Solution

  • That is super easy since it is already implemented. Just include the following in the YAML (in addition to all the other stuff in your YAML):

    output:
  xaringan::moon_reader:
    nature:
      ratio: '16:9'

    Here's my default start YAML. Maybe you can tweak that to your desires.
