I am a rookie learning to develop web sites. To this point I have been just making pages without any regard of screen resolutions. As I have been doing some research I see that everyone says to stay around 900 pixels wide.
With the size of monitors and screens today that seemed a little small. Am I making too much of this or should I be adhering to some type of screen resolution rules or nothing at all?
I do work for many media agencies and they prefer the rule of thirds in their designs so they tend to stick with the 960 pixels grid system. You can read more in Optimal width for 1024 pixels resolution?.
It flows better and allows for late adopters to see your full site without scrolling.. That said, what is your target and what are the usage stats for that group?
