User:Dr pda developed a very helpful script that can list the length of good articles by prose size. This is the output of that script as of 1 September 2014. Note that this is not the size of the article you will see in the history, but the length of the text in the article minus blockquotes, references, etc. A list of good articles by sheer amount of wiki text is at User:The ed17/Good articles by wiki text. See also User:The ed17/Featured articles by prose size, User:The ed17/Featured articles by wiki text, and User:Dr pda/Featured article statistics.
