About 9% of web visitors are still using 640x480 at 256 color screen resolution, and the website needs to look okay in this mode. It can be optimized for 800x600 (used by about 35% of visitors) but is best not requiring any higher resolution than this. Special websites or pages may be designed for 1024x768 (used by about 40% of web visitors).
