Where is the font size setting?
Making text bigger is the most inconsistently named setting we have measured: nine different labels across the systems that offer it. We read the settings tree of all 43 systems in the catalogue and recorded where each one keeps it.
What each system calls it
19 of the 43 operating systems in our catalogue have this setting, and between them they use seven different labels for it:
| Name on screen | Systems |
|---|---|
| Text size | 5 |
| Display & Text Size | 3 |
| Text Size | 3 |
| Font Size | 2 |
| Text and display size | 2 |
| Font size | 1 |
| Display and Text Size | 1 |
| Font | 1 |
| Display size | 1 |
The most common is Text size, on 5 of the 19. If that is not the word on your screen, the table above is the rest of the vocabulary to try.
Some of those rows differ only in capitalisation — 9 spellings for seven actual names. We have kept them apart because that is what is printed on the screen, and a settings search that matches case will tell them apart too.
Where it lives on each system
These are the shortest paths from the first settings screen on the newest release of each system. 13 of the 19 are within two taps; the rest sit deeper, and the table shows how much deeper.

Why the names came out this way
The fragmentation comes from a genuine disagreement about what is being changed. Font size changes a typeface measurement. Text size changes what you read. Display size changes everything, including icons and layout. Three different promises, and some systems offer two of them on the same screen.
This matters more than most naming problems, because the people who need this setting are the least likely to enjoy hunting for it. It is the strongest argument in the catalogue for searching by what you want rather than by what it might be called.
Find it on your own device
If your system is not in the table, or the label on your screen is different again, there are three ways through it:
- Search every system at once for a setting by name — it looks inside all 43 trees, not just the one you are holding.
- Open your own system in the settings simulator and click to the screen without changing anything real.
- Follow the step-by-step guide to switching to dark mode, or see where that setting lives on every system.

Where is the font size setting on most systems?
On 13 of the 19 systems that have it, within two taps of the first settings screen. The most common label is “Text size”, used by 5 of them. The table above gives the exact path for each system.
Why can I not find it by searching my settings?
Because settings search matches the label your system uses, and there are seven different labels in use for this one setting. Searching for the word your previous device used is the single most common reason a setting appears to be missing.
How many systems have this setting at all?
19 of the 43 operating systems we catalogue. The rest either have no hardware for it or fold the behaviour into something else, which is why a feature that feels universal often is not.
