Use of type in the desktop: Semantic use of fonts in the interface

Registered by Iain Farrell

Most GTK themes, including Ubuntu’s Light themes, currently use a single font — one typeface in one size and one weight — for nearly all interface elements. This makes some things harder to see than they should be, some things larger than they should be, and generally looks monotonous.

To fix this, we should evaluate what exactly Ubuntu does, what other operating systems do, what would look most beautiful, and how we will achieve it.

There is a single system-wide application font option, which is used almost everywhere. At the moment, applications need to define fonts very manually. On the other hand, MacOS X and Windows have a huge variety of font styles that application developers can choose for particular cases.

We need to identify different font styles that would be useful across applications. Find a general set of styles. One approach is to collect screenshots from a variety of desktop applications in Ubuntu and make notes about how they can be fine-tuned. These styles should all build on a baseline font that the user can configure as usual.

From the baseline different siuations will scale up or down and users will be able to adjust around these baselines if they want to.

Should identify information hierarchy for a number of applications
 - Appearance prefs
 - Font prefs

Define Compact windows, which should have smaller font sizes than application main windows.

Actively discourage developers from using arbitrary, absolute values for fonts; we should make sure applications move towards font styles instead.

Controls like for example the choose font list box could be a lesser opacity so user is drawn more to content they want to interact with.

Baseline: Checkbox
Slider values: Smaller than baseline
Titlebar: unique case - leans towards larger
Control captions: smaller
Table headings: smaller, bolder
Button labels: Equal
Tab headings: larger - should explore this as may be a problem in other languages where tabs are long
menu: larger
Dialog section heading: same as baseline, bolder (maybe also larger, different colour)
