In addition to your post
How big is the ozone layer?
To me The average area of the hole observed since 1991 has been roughly 10 million square miles. In 2015 the ozone hole grew to 10.9 million square miles, 2 million square miles larger than this year, before returning to relatively normal summer levels.
