Fluid page designs are supposed to be nice, at least in theory, but if you don't control the page presentation it is hard to maximize the advertising offer opportunity and to blend ads into the layout as best you can.
A page width set to 100% gives the ads a relatively small % of the screen width unless the ads are huge, and huge ads get ignored because they scream I AM AN AD.
If the content area is exceptionally wide it makes a page hard to read due to making the eye move further left to right on each line than is comfortable.
If you limit the page width but align it to the left the ads still may not get clicked as much because they may not be viewed as well if they are on either side of the content.
So, to make more bank per page view, it makes sense to set a page width and center the page. If you still want to make the page somewhat liquid but controllable to a maximum width you may want to use max width.
760 px is a common page width. People are migrating to bigger browsers, but more people will also be connecting to the web on mobile devices.
Another good AdSense tip is to match (or nearly match) your text size and font to that of the AdSense ads
Depending on your ad units sometimes the size may change. If you right click on an AdSense frame you can view the source of that frame to get that information.
Many designers recommends setting text sizes using em instead of pixels.
