Wikipedia: Wikipedia statistics/Size of Wikipedia

The Wikipedia statistics referring to the size of Wikipedia; mostly page and article count. For interest's sake, the advertisements for Encyclopedia Britannica's 2002 edition proudly proclaim they have over 85 000 articles.

So far, most of this has been drawn from Wikipedia Announcements.

How it's measured

The general goal has been to make as conservative a count as possible, by excluding anything that may be considered a non-article.
