You can see that once again I am being assertive. Why design for just this one monitor resolution? And, accepting my rule 1, exactly what fixed width ‘page’ does this imply?
The facts of monitor resolution are worth being aware of. In the year since I last analysed the statistics of visits to my small personal site, the variety of monitor resolutions has increased. There isn’t space here to list them. Look simply at the last 10 visits I received: 4 visitors had monitors set to 1024×768, 2 had monitors set to 1280×1024. The other 4 had monitors set to 1120×840, 1280×800, 1440×900, and 1680×1050 (1 each).
Apart from the variety, there are two things that can be learned even from this small example (and they are borne out by the total statistics). All of the visitors had monitors set to at least a width of 1024 pixels (most had more). And there isn’t one visitor with a monitor set to 800×600 (which some backward-looking people think we should still take as the norm).
I can imagine your response. Isn’t this a bit arbitrary? Might we not restrict our creativity this way? Hasn’t there been a long debate in the Web design community about the merits of fixed and fluid designs—and isn’t it still an open question?
