Wikipedia:Typography

Typography, i.e. the use of fonts, on Wikipedia can often be a source of heated debates. This is because Wikipedia has never set an explicit font in its default skin. This was true for Monobook, and still holds for Vector. The base font for these skins are simply defined as font-family: sans-serif. Likewise, the size of fonts are also subject to debates. Vector uses the definition of font-size: 0.875em;, which translates to 87.5% of the default fontsize set in a user's browser. Under Windows, the default fonts in browsers are normally defined as Arial at 16px for sans-serif, Times New Roman at 16px for serif and Courier New at 13px for monospace. 0.875 × 16 equals 14px exactly. However, all fonts shown here are 16px, the browser's default.

Below are some personal writings on web typography, and its potential use on Wikipedia. It focuses on fonts that are installed by default, as these provide a stable installed base. It also focuses heavily on Windows. Information relating to other platforms is very welcome.
