Font Examples
Below are some personal ramblings on web typography, and it's potential use on Wikipedia. I focus on fonts that are installed by default, as these provide a stable installed base.

Font comparison
Fonts that have the same cap height, do not always match in x-height, making them hard to mix inline without scaling. The most widely available fonts are:

Core fonts for the Web
Based on Arial as the base font, Comic Sans MS, Georgia , Trebuchet MS and Verdana are safe to use inline. Times New Roman is not safe to use inline without scaling. Although Courier New has a lower height, it remains eligable, and is the defacto monospace font. (Arial Black and Impact are not listed, as these are header fonts.)

The Core fonts for the Web have an installed base of 99% on the Windows (except Andale Mono) and 92–98% on Mac OS X platforms, as they are now part of the standard installation. Despite the necessity to install these fonts seperately, they still enjoy an installed base of 65% among Linux installation.
 * Availablility

Originally part of the Core Web fonts, Andale Mono is not installed with Windows (having been replaced by Lucida Console), resulting in only 4% of Windows installations having the font, as opposed to 92% on Mac OS X. It used to be shipped with Internet Explorer until version 6, and was only installed with Windows 98. As the fonts are stil available online, it does have an installed base of 65% on Linux. As it is similair and metric-compatible to Lucida Console, it is recommended to always combine Lucida Concole and Andale Mono in a font stack.

Common Windows fonts
All but Palatino Lynotype end Segoe UI have one major drawback: they all come without either bold and/or italic variants.

ClearType collection
The "new" Windows ClearType font family introduced in Windows Vista has consistent font metrics, but these do not match with the core web fonts listed above, so they need to be scaled when mixed.

Monospace fonts
When displaying code, a monospace font helps keep code readable and maintain formatting consistent, but there are caveats. Below are some common monospace fonts.

Not all monospace fonts come with a bold weight variant, causing bold text to mis-align with the rest of the text. Andale Mono and Lucida Console suffer badly from this. That leaves Courier New and Conslas as the only safe choices when bold and italic highlighting is used.
