Design/Typography

Typeface Selection
Wikimedia Foundation projects must provide a consistent experience to every user on the planet. The typographic goals for Wikimedia Foundation interfaces include: Pursuant to these goals, we have selected Arial as our global typeface for all content and interface elements. The primary reasons for this are: This selection may change as other typefaces develop ubiquity. However, in the near future, Arial will continue to serve as WMF's standard typeface with sans-serif as a fallback.
 * Readability: We must select typefaces that are screen-reader friendly.
 * Accessibility: We must not inhibit readability for users with visual impairments (including dyslexic individuals).
 * Availability: All typefaces we use must be already available, or made available, to our users.
 * Arial is freely available on nearly every computer and operating system on the planet.
 * Arial is a sans-serif, screen-friendly typeface.
 * Ubiquitous serif typefaces (e.g. Times New Roman) were excluded because they are not as readable to dyslexic readers.

Sizing Nomenclature
This document refers to font sizes in hard points. This is for demonstration and documentation purposes only. During implementation, font sizes should be described in em units.

Code Snippet Context
Each code snippet on this page is self-contained, unless stated otherwise. This is done to allow individual snippets to be pasted into Wikimedia Foundation projects on an experiment-by-experiment level. Eventually, each of these design standards will be integrated into our core CSS library. When this occurs, style names and additional guidelines will be updated on this page.

Note: Convert pt units to em units prior to utilizing these snippets.
