Fonts & text size
The sky — your home screen — has its own text: star labels, region numbers, the clock and date, and the weather and battery readouts. This page sets the typeface and the size of that text, apart from the theme. It all lives in Settings › fonts & text size.
Font family
What it is. The typeface for all of the sky's on-screen text. Each choice shows as a chip drawn in its own face, so you preview it in place.
Options. The default (the theme's own face), plus "sans", "serif", "mono", "cursive", and the installed system faces "sans light", "sans thin", "sans medium", "condensed", "sans black", "serif mono", and "casual". A face your phone doesn't have falls back to the default.
Default. The theme default. Find it at Settings › fonts & text size › font.
Size — one master, then per-element
Size works in two layers. A master multiplier scales all the sky's text at once, and each element then multiplies on top of it. In every slider, 100% is the normal size.
Master. "master — all sky text" scales everything together. Default 100%; slider range 60–250%. Find it at Settings › fonts & text size › size.
Star labels. "star labels" sizes the text under stars. Default 100%; range 50–300%.
Clock & date. "clock & date" sizes the clock and date overlay. Default 100%; range 50–300%.
Weather & battery. "weather & battery" sizes the weather, battery, and next-event overlay text. Default 100%; range 50–300%.
Region numbers. "region numbers" sizes the 1–9 shown in each region — a zone of the sky that groups stars. Default 100%; range 0–300%. Set it to 0 to hide the region numbers entirely.
A separate accessibility text size
If you use a screen reader or need larger text for reading rather than styling, the accessibility page has its own "star label text size" and "clock & overlay text size" controls, separate from the sliders here. See Accessibility & motion.
