1.3.4 Orientation (Level AA)

Content should display in the orientation that works best for the user.

What you need to know

  • People with low vision will be able to view content in the orientation that works best for them.
  • Flexibility of orientation is especially important for people who have their phone or laptop mounted in a fixed orientation, for example on the arm of a scooter.

What you need to do

  • Unless absolutely necessary, make sure that your website or app and its content can display well in both portrait (vertical) and landscape (horizontal) mode on phones, tablets, etc.
  • Style your website so that it does not lock on or require a single display mode.
  • Don’t restrict content to view on a single display orientation (i.e., portrait or landscape) unless necessary.
