Most computers have a means of adjusting the size of the font displayed on the screen; you should view your website at the largest font sizes to see if text or graphics superimpose on one another. This is particularly important if websites have multiple columns. In Windows Vista, just "right-click" on the desktop, select "Adjust Font Size (DPI)" from the left-hand column and try each of the following settings (possibly at different screen resolutions as Discussed in Example Three):
First, try "Larger Scale (120 DPI)"
Then, try "Custom Scale" by clicking on the "Custom DPI" button; we would suggest viewing your website at the 200% setting at several different screen resolutions, on several different monitors, computers and/or operating systems.
Finally, just to be safe, we would suggest trying the 125% and 150% settings.
Be sure to check the functionality of the various pages of your website at different font sizes and different screen resolutions. If you have drop-down menus, java features, or other special effects, pay particular attention to how these appear on differently configured computers.
