DPI (Fineness) of Displays
You can learn the fineness of the resolution in relation to the display size from the values of the following table.
The values are indicated in DPI (= dots per inch).
Following images show the relative display size and how much "space" remains at the screen with Windows XP (with the standard setting of 96 DPI).

Comment
Starting from approximately 110 DPI a display is for most users (with operating systems, which make the representation size dependent on the resolution, like Windows XP) too finely resolved (representation too small).
High DPI values especially are an advantage for the handling with images and tasks of programming (much place at the screen). In addition it must be considered with laptops, that the user sits usually much nearer at the screen (because of the close, fixed keyboard).
