What is the maximum width a website should be? I want to make a very wide website however I don't want it to have to scroll across on certain resolutions etc..
This is just an opion. Rather than having a fixed width site, why not use a fluid css layout. There a ton of templates for this on the web. In any event, my monitor is set to 1280 wide. I can't read it with much more resolution than that.
1024px is the minimum resolution a website should be build for, since there are still a lot of people out there using this resolution. Since you also have to watch out for browsers making this resolution a little smaller with their borders and scrollbars, a maximum width of 950 - 1000 px is suggested.
I agree with Masteroa. The number of people using 1024px resolution is still very high. Unless you know for a fact that most of your visitors will be using a higher resolution, you should stick with a width of around 980px for a fixed-width layout or a min-width of around 980px for a fluid layout.
The standard size to design for is 1024, which is stated above, For a fixed width using 960px is the best way to go about it.
IMHO, for fixed width, 960 is the safest choice. It will fit on most screen, and still readable on 800x600.
Take the lowest resolution you want to support and subtract 20px for the scroll bar on the right of the browser. 800x600(780px), 1024x768(1004px) etc
So only 1% of the world is using 800 x 600 now, I guess there is no need to make websites to fit that resolution then.
As of 2 March 2010, the Earth's human population is estimated by the United States Census Bureau to be 6,805,900,000. So approximately 68,059,000 people still use 800x600?
