According to Ohloh, as of August 2011 the Chromium codebase consists of about five million lines of code, and 1.7 million lines of comments and blanks, though there's probably a lot of wiggle room depending on how you slice it (it includes third_party code, tests, chromeos-specific bits etc):

I'm pretty sure that number doesn't include WebKit (since the reported size of the WebKit codebase was bigger than the Chromium codebase in 2008), which is an additional 3.6 million lines (+1.5 million in comments and blanks):
