How to customize Attachment Display Settings available Size?

  • I want to add 420×747 image size option to the Insert Media>Attachment Display Settings>Size. Then I changed “Media settings>Image sizes” medium image size as “420×747”. But still I can’t see the updated size in the “Insert media” window.

    How do I add my own size?

    Thanks!
