This site: http://shoryuken.com/forum/index.php seems to have a 1250px width standard, but goes down to about 1000px if you scale your browser window. I don't know how to achieve this since width: overrides min-width:. Anyone?
I don't, but if you measure it it's 1250px (take or give a few px). I wasn't able to find where they set a width. In any case I solved it by using width: 100%, max-width: 1250px, min-width: 1000px.
