Why Are Some Websites Different Widths?

by on December 22, 2006

Q: I upgraded from a 17″ to a 19″ monitor. When I go to some websites there is about a 4″ wide strip on the right of the screen that has nothing on it. However, when I go to other websites the screen is completely covered with information. Why does this happen?

A: All web pages are designed differently. Some web page authors will use % constraints (i.e. My page will take up 90% of available screen size) where others will hard set the resolution for viewing so they will take up X number of pixels no matter how large your screen is. With your newfound monitor you have a higher resolution, which means you can fit more data on your screen. This is why pages that are set to only show X number of pixels have extra space around them as you have seen.
