Recommended max-width for 1024x768

What is recommended width for wrapper blocks (main containe开发者_开发知识库rs) on 1024x768 resolution?

There should not be horizontal scroll on that width in most available browsers.

If you Google for browser chrome dimensions, you will find a number of sites that provide this information. E.g.:

http://webdesign.about.com/od/webdesignbasics/a/aa041607.htm

The max available width depends on the browser AND the OS. A width of 968px should fit in all system, but a width of 960px has become almost standard for many pages. There is also a page about 960px grid layouts you can find here: http://960.gs/

900px is the ideal one. Hopefully it should come up with scroll bar on opera 9 (It doesn't come up with scroll bar for other major browsers).
