Help Please

I was working on a draft when it suddenly turned into a narrow column in the center of the page with tiny type and I can’t seem to restore it to what it was. Can someone tell me what I did and how to restore/fix it?

Don’t have an answer for you but would suggest you post in the iOS Tech Support forum (viewforum.php?f=53) since the little OS indicator says you’re working in Scrivener for iOS. (If not so, please disregard.) Hope you get an answer soon. Good luck.
