Make sure that learners can resize your eLearning resource up to 200% without loss of content or functionality, without using assistive technology such as a screen magnifier.

How do I comply?

  • This is often automatically achieved in eLearning resources depending on the authoring tool you are using. Check with your provider to see if this is the case.
  • You can also test the eLearning resource yourself using the zoom option in any browser. You should be able to enlarge the eLearning resource and therefore the text by 200%.
  • When you enlarge the resource, you should still be able to see all of the content and carry out all of the same functions as you could before you enlarged it.
  • Sometimes the ability to enlarge, can be affected by the publishing options you choose when creating your eLearning output. In Storyline for example, it is possible to choose a publishing setting Scale player to fill browser window which locks your eLearning to a particular size. This option should not be chosen as it will mean that the learner will not be able to resize the eLearning resource and the text.


  • This standard can help all learners who will benefit from enlarging the text, e.g learners with low vision.

eLaHub example

(No audio)

Storyline page enlarged using Chrome browser

Video shows:
An eLearning page viewed using the Google Chrome browser. The learner uses the zoom functionality in the browser to enlarge the slide from 100% to 200%. The video shows that it is still possible to read the text and see all the content at this size.

How can I test?

Use the zoom function in any web browser to check that you can enlarge the text in your eLearning resource, up to 200%, without loss of content or functionality.
