New Minimum Font Size

The good people of Microsoft User Experience and Microsoft Typography have found that the minimum font size used on computer screen is too tiny for modern computer displays. The absolute minimum size used to be Tahoma 8pt (comparable to 11px on Mac OS X or on the web).

But, as the average screen display has moved from 640x480 to 1024x786 (and above) the font has simply become illegible for most people. Evidently, this is caused by the average screen resolution has increased more rapidly than the use of larger displays. It is a problem that has become profound on most laptops, and noticeable on many desktop systems.

To fix this Microsoft has developed a new font - Segoe UI (pronounced, "SEE-go"), and changed the minimum from 8pt to 9pt. But, that is not all. The new font has also been designed specifically for ClearType, and has been given a more human appearance than Tahoma.

Now you should use:
