How to measure the "size" of a webpage?

How do I go about measuring the total download size of a webpage? (complete with all of its pictures on that page, etc)?

They are very conservative when they say something has too much crap loading, just use your own judgment... but it will measure it for you

Web Developer Toolbar for FireFox, under "information" -> "view document size"

Safari's developer tools will also show you the total size of all files downloaded. I believe firebug/yslow also do the same thing.
