There was a time when 800x600 resolution was used for websites because 14" monitors was IN but now they are used very less. Now 17" monitors have taken their place. So the usage of monitors will decide what website resolution to be used? or you will see the content of your site, if you have more content you will use 1024 resolution and if you have less content then you will go with 800 resolution. How do you decide that? I prefer setting the website resolution based on the size of the content. If you have less content and you use 1024 resolution then your site will have lots of empty space, vice versa for more content and less resolution. What is your thought about it?
I go with 950px most of the time. 90% of people that use the internet can view 850-950px without having to scroll left or right, so that's a fair size. Here's a page from Google that may help you out: http://browsersize.googlelabs.com/
Hello ! I personally use between 950px to 1000px. One thing that needs to be kept in mind that the viewer does not has to scroll left or right to view the page. That looks un professional. Now as far as length is concerned. That should be dependent on the content quality. Regards.
while doing page set up ,choose 100 % and for that you have to convert pixles or inches etc. into Percentage and it will be auto set .
